Note: Electrical characteristics mentioned above are the values at JIS standard condition (temperature 15 to 35degC, relative humidity
25 to 75%, atmospheric pressure 86k to 106kPa) unless otherwise specified.
Note: Care shall be taken on the heat generated on PC board when maximum carrying current exceeds 10A.
Please perform the confirmation test with actual conditions.
*¹: 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 reliabilitylevels.
*² : Electrical life at resistive load mentioned above are the values when a varistor or zener diode or zener diode+diode is used as coilsuppression device. Using protection device other than these, the contact life expectancy may decrease drastically.
When using a varistor as a suppression device, varistor voltage shall be approximately twice the voltage applied to the coil andconnect it in parallel with the coil. When using a zener diode or zener diode+diode as a suppression device, please refer to theCIRCUIT DIAGRAM WHEN USING ZENER DIODE.

CAUTIONS• All values mentioned in this datasheet are provided under ideal conditions. Please perform the confirmation 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 mayincrease.
• Do not use silicon or silicon-containing product or materials near relays. It may cause contact failure.
• Please connect relay coils according to specified polarity.

Cautions for high voltage DC switching relays• There is a possibility that the relay is not able to switch off the load at high voltage DC load. Fail safe circuit must
be provided to prevent injury, fire or other harms resulting from failure occurred on relays.
• Relays are periodic maintenance parts. Do not exceed the specified life time and/or switching conditions.

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.

Flow Solder Condition:Solder by Solder Iron:

Pre-heating: Maximum 120℃
within 90 sec.
Soldering: Dip within 5 sec. at 255℃±5℃ solder bath

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

Relay must be cooled by air immediately after soldering

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 lengthwhisker was found by our in house test.
