Block Type EMIFILr SMD Type !Caution/Notice
● Notice (Soldering and Mounting)
<Operating Environment>
Do not use products in a chemical atmosphere such as
chlorine gas, acid or sulfide gas.
Do not use products in the environment close to the
organic solvent.
<Storage and Handling Requirements>
1. Storage Period
BNX series should be used within 12 months.
Solderability should be checked if this period is
exceeded.
2. Storage Conditions
(1) Storage temperature: -10 to +40˚C
Relative humidity: 15 to 85%
Avoid sudden changes in temperature and humidity.
(2) Do not store products in a chemical atmosphere
such as chlorine gas, acid or sulfide gas.
1. Cleaning
Do not clean BNX series (SMD Type).
Before cleaning, please contact Murata engineering.
2. Soldering
Reliability decreases with improper soldering methods.
Please solder by the standard soldering conditions
shown in mounting information.
3. Other
Noise suppression levels resulting from Murata's EMI
suppression filters EMIFILr may vary, depending on
the circuits and ICs used, type of noise, mounting
pattern, mounting location, and other operating
conditions. Be sure to check and confirm in advance
the noise suppression effect of each filter, in actual
circuits, etc. before applying the filter in a commercial-
purpose equipment design.
● Rating
!Caution
● Handling
1. Resin Coating
Using resin for coating/molding products may affect
the products performance.
So please pay careful attention in selecting resin.
Prior to use, please make the reliability evaluation with
the product mounted in your application set.
Do not use products beyond the rated current and rated
voltage as this may create excessive heat and
deteriorate the insulation resistance.
● Storage and Operating Conditions
Notice
2. Handling of a Substrate (for BNX02p)
After mounting products on a substrate, do not apply
any stress to the product caused by bending or
twisting to the substrate when cropping the substrate,
inserting and removing a connector from the substrate
or tightening screw to the substrate.
Excessive mechanical stress may cause cracking in
the Product.
Bending Twisting

conditions shown in mounting information.
3. Other
Noise suppression levels resulting from Murata's
EMI suppression filters "EMIFIL" may vary,
depending on the circuits and ICs used, type of

1. Standard Land Pattern Dimensions
Soldering and Mounting
Block Type EMIFILr SMD Type
When reflow soldering the block type EMIFILr, the
printing must be conducted in accordance with the
following cream solder printing conditions.
If too much solder is applied, the chip will be prone to
damage by mechanical and thermal stress from the PCB
and may crack.
Standard land dimensions should be used for resist and
copper foil patterns.
BNX022

(1) A double-sided print board (or multilayer board) as shown in
the left figure is designed, and please apply a soldering Cu
electrode with a product electrode to a "Land Pattern", apply
resist to a "Land Pattern + Solder Resist" at Cu electrode.
(2) This product has large rated current of 10A/15A. Please
consider real current and make Cu electrode thick enough.
(Please design line resistance suitable for real current)
(3) Please drop CG on a ground electrode on the back layer
(the same also in a multilayer case) by the through hole. And
a surface grand electrode layer may also take a large area
as much as possible.
(4) It is recommended to use a double-sided printed circuit
board with BNX mounting on one side and the ground
pattern on the other in order to maximize filtering
performance, multiple feed through holes are required to
maximize the BNX's connection to ground.
(5) The ground pattern should be designed to be as large as
possible to achieve maximum filtering performance.

Do not clean BNX022/023/024/025 series. In case of cleaning, please contact Murata engineering.
(3) Reworking with Solder Iron
The following conditions must be strictly followed when
using a soldering iron.
Pre-heating: 150°C 60s min.
Soldering iron power output: 100W max.
Temperature of soldering iron tip / Soldering time / Times:
450°C max. / 5s max. / 1 time
Do not allow the tip of the soldering iron to directly
contact the chip.
For additional methods of reworking with a soldering iron,
please contact Murata engineering.
3. Standard Soldering Conditions
(1) Soldering Methods
Use reflow soldering methods only.
Use standard soldering conditions when soldering block
type EMIFILrSMD type.
In cases where several different parts are soldered, each
having different soldering conditions, use those
conditions requiring the least heat and minimum time.
Solder: Use Sn-3.0Ag-0.5Cu solder. Use of Sn-Zn based
solder will deteriorate performance of products.
Flux:
o Use Rosin-based flux.
In case of using RA type solder, products should be
cleaned completely with no residual flux.
o Do not use strong acidic flux (with chlorine content
exceeding 0.20wt%)
o Do not use water-soluble flux.
For additional mounting methods, please contact Murata.

This product effectively prevents undesired radiation and
external noise from going out / entering the circuit by
grounding the high frequency components which cause
noise problems. Therefore, grounding conditions may affect
the performance of the filter and attention should be paid to
the following for effective use.
(a) Design maximized grounding area in the P.C. board,
and grounding pattern for all the grounding terminals
of the product to be connected. (Please follow the
specified recommendations.)
(b) Minimize the distance between ground of the P.C.
board and the ground plate of the product.
(Recommend unsing the through hole connection
between grounding area both of component side and
bottom side.)
(c) Insert the terminals into the holes on P.C. board
completely.
(d) Don't connect PSG terminal with CG terminal directly.
(See the item 1. Terminal Layout)
(1) How to use effectively
Use a bilateral P.C. board. Insert the BNX into the P.C.board until
the root of the terminal is secured, then solder.

Though this product has a large rated current, localized
selfheating may be caused depending on soldering
conditions. To avoid this, attention should be paid to the
following:
(a) Use P.C. board with our recommendation on hole
diameter / land pattern dimensions, mentioned in the
right hand drawing, especially for 4 terminals which
pass current.
(b) Solder the terminals to the P.C. board with
soldercover area at least 90%. Otherwise, excess self-
heating at connection between terminals and P.C.
board may lead to smoke and / or fire of the product
even when operating at rated current.
(c) After installing this product in your product, please
make sure the self-heating is within the rated current
recommended.

4. Cleaning
Clean the block Type EMIFILr(Lead Type) in the following
conditions.
(1) Cleaning temperature should be limited to 60°C max.
(40°C max for alcohol type cleaner).
(2) Ultrasonic cleaning should comply with the following
conditions, avoiding the resonance phenomenon at the
mounted products and P.C.B.
Power: 20W/liter max.
Frequency: 28 to 40kHz
Time: 5 min. max.
(3) Cleaner
(a) Alcohol type cleaner
Isopropyl alcohol (IPA)
(b) Aqueous agent
Pine Alpha ST-100S
(4) There should be no residual flux or residual cleaner left
after cleaning.
In the case of using aqueous agent, products should be
dried completely after rinsing with de-ionized water in
order to remove the cleaner.
(5) The surface of products may become dirty after cleaning,
but there is no deterioration on mechanical, electrical
characteristics and reliability.
(6) Other cleaning: Please contact us.
(1) Use Sn-3.0Ag-0.5Cu solder.
(2) Use Rosin-based flux. Do not use strong acidic flux with
halide content exceeding 0.2wt% (chlorine conversion
value).
(3) Products and the leads should not be subjected to any
mechanical stress during the soldering process, or while
subjected to the equivalent high temperatures.
