Notes

• These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing over

operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime.

1. The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heatflow support of the

printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded. Furthermore, a

high level of ambient temperature or of power dissipation may raise the temperature of the solder joint, hence special solder alloys or board

materials may be required to maintain the reliability of the assembly.

2. Specified power rating requires dedicated heat-sink pads.

3. Film temperatures above the specified range may be permissible, e.g. 175 °C. Please contact the factory for details.

Note

1. Color code marking is applied according to IEC 60062* in four bands. Each color band appears as a single solid line, voids are permissible

if at least 2/3 of the band is visible from each radial angle of view. The last color band for tolerance is approximately, 50 % wider than the

other bands. A brown interrupted band between the 2nd and 3rd full band indicates the special carbon film type.

Note

2. Please select resistance values for ± 5 % and ± 2 % tolerance from the E24 series.

DESCRIPTION

Production of the CMB 0207 speciality MELF resistor is

strictly controlled and follows an extensive set of instructions

established for reproducibility. A homogeneous and dense

carbon film is deposited on a high grade ceramic body

(96 % Al2O3). Nickel plated steel termination caps are firmly

pressed on the coated rods. Products with a resistance of

15 Ω or lower are made without trimming, whereas a special

laser is used to achieve a target value of 16 Ω or above

by smoothly cutting a helical groove in the resistive layer

without damaging the ceramics. The resistor elements are

covered by a protective coating designed for electrical,

mechanical and climatic protection. The terminations receive

a final pure tin on nickel plating. Four color code rings

designate the resistance value and tolerance in accordance

with IEC 60 0623).

The result of the determined production is verified by an

extensive testing procedure performed on 100 % of the

individual resistors. Only accepted products are laid directly

into the blister tape in accordance with IEC 60 286-33).

ASSEMBLY

The resistors are suitable for processing on automatic

SMD assembly systems. They are suitable for automatic

soldering using wave, reflow or vapour phase as shown in

IEC 61760-13). Excellent solderability is proven, even after

extended storage in excess of 10 years. The encapsulation

is resistant to all cleaning solvents commonly used in the

electronics industry, including alcohols, esters and aqueous

solutions. The resistors are completely lead (Pb)-free, the

pure tin plating provides compatibility with lead (Pb)-free

soldering processes. The immunity of the plating against tin

whisker growth has been proven under extensive testing.

All products comply with the GADSL1) and the CEFIC-

EECA-EICTA2) list of legal restrictions on hazardous

substances. This includes full compliance with the following

directives:

•2000/53/EC End of Vehicle life Directive (ELV) and

Annex II (ELV II)

•2002/95/EC Restriction of the use of Hazardous

Substances Directive (RoHS)

•2002/96/EC Waste Electrical and Electronic Equipment

Directive (WEEE)
