NOTES ON CORRECT USE
(1) The space between PC board and root of the lead should be kept more than 1 mm to prevent undesired stress
to the lead and also should be kept less than 4 mm to prevent undesired parasitic inductance.
Recommended that space is 2.0 to 3.0 mm typical.
(2) Recommended torque strength of the screw is 59 to 78 Ncm.
(3) Form the ground pattern as wide as possible to minimize ground impedance.
(to prevent undesired oscillation)
All the ground pins must be connected together with wide ground pattern to decrease impedance difference.
RECOMMENDED SOLDERING CONDITIONS
This product should be soldered and mounted under the following recommended conditions. For soldering
methods and conditions other than those recommended below, contact your nearby sales office.
Soldering Method Soldering Conditions Recommended Condition Symbol
Partial Heating Peak temperature (pin temperature) : 350°C or below Note
Soldering time (per pin of device) : 3 seconds or less
−
Note The point of pin part heating must be kept more than 1.2 mm distance from the root of lead.

Subject: Compliance with EU Directives
CEL certifies, to its knowledge, that semiconductor and laser products detailed below are compliant
with the requirements of European Union (EU) Directive 2002/95/EC Restriction on Use of Hazardous
Substances in electrical and electronic equipment (RoHS) and the requirements of EU Directive
2003/11/EC Restriction on Penta and Octa BDE.
CEL Pb-free products have the same base part number with a suffix added. The suffix –A indicates
that the device is Pb-free. The –AZ suffix is used to designate devices containing Pb which are
exempted from the requirement of RoHS directive (*). In all cases the devices have Pb-free terminals.
All devices with these suffixes meet the requirements of the RoHS directive.
This status is based on CEL’s understanding of the EU Directives and knowledge of the materials that
go into its products as of the date of disclosure of this information.
