Minimum switching loads mentioned above are reference values. Please perform the confirmation test with actual load before production
since reference values may vary according to switching frequencies, environmental conditions and expected reliability levels.
Care shall be taken on the heat generated on PC board when maximum carrying current exceeds 10A. Please perform the confirmation test withactual conditions.

CAUTIONS
・All values mentioned in this datasheet are provided under ideal conditions. Please perform the confirmation test before
actual use.
・Reflow soldering is prohibited for flow soldering type.

・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 commissiondelegated 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 beenverified to be compatible with PbSn assembly process.

•Recommended solder for assembly: Sn-3.0Ag-0.5Cu.

Important Notes for reflow Soldering•••

Temperature shall be measured at PC boartd uppler surface.
Temperature at PC board upper surface may be changed depending on size of PC board, components mounted
on the PC board and/or heating method. Please perform the confiramtion test with your actual PC board.
This reflow condition is applicable only for reflow-capable relays. Do not reflow reflow-incapable relays.

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

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.
