FBR53-HW SeriesCAUTIONS・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 mayincrease.
・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

Flow Solder Condition:

Pre-Heating:maximum 120˚C
within 90 sec.
Soldering:
dip within 5 sec. at 255°C±5°C
solder bath
Relay must be cooled by air immediately aftersoldering

Solder by Soldering Iron:

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

Reflow Solder Condition:(Applicable only for reflow capable type)

Recommended reflow soldering profileIRS (infrated reflow soldering)Temperature (°C)•

been verified to be compatible with PbSn assembly process.
Recommended solder for assembly: Sn-3.0Ag-0.5Cu.

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.
