CAUTIONS
・All values mentioned in this datasheet are provided under ideal conditions. Please perform theconfirmation test before actual use.
・Reflow soldering is prohibited.
・Do not use relays in the atmosphere with sulfide gas, chloride gas or nitric oxide. Contact resistance
may increase.
・Do not use silicon or silicon-containing product or materials near relays. It may cause contact failure.

GENERAL INFORMATION
1. ROHS Compliance• All relays produced by FCL Components are compliant with RoHS directive 2011/65/EU, including
commission delegated directive 2015/863.

2. Recommended lead free solder condition• Lead free solder plating on relay terminals is Sn-3.0Ag-0.5Cu, unless otherwise specified.
•This material has been verified to be compatible with PbSn assembly process.
Recommended solder for assembly: Sn-3.0Ag-0.5Cu.

Flow Solder Condition:
Pre-Heating:Soldering:

Maximum 120˚C within 90 sec.
Eip within 5 sec. at 255°C±5°C solder bath

Relay must be cooled by air immediately after soldering

Solder by Soldering Iron:

Soldering Iron: 30-60W
Temperature: Maximum 340-360˚C
Duration:
Maximum 3 sec.

We highly recommend that you confirm your actual solder conditions
3. Moisture Sensitivity• Moisture Sensitivity Level standard is not applicable to electromechanical relays, unless otherwiseindicated.

4. Tin Whiskers• Dipped SnAgCu solder is known as presenting a low risk to tin whisker development. No considerable
length whisker was found by our in house test.
