n RECOMMENDED SOLDERING CONDITIONS FOR SMT (SEE PAGE 9)
(TEMPERATURE PROFILE)
Notes:
1. Temperature proles on page 9 show the temperature of PC board surface.
2. Please perform soldering test with your actual PC board before mass production, since the temperatures of PC board
surfaces vary according to the size of PC board, status of parts mounting and heating method.
n PRECAUTIONS
- For details on general precautions, refer to the section on technical descriptions.
- Since this is a polarized relay, follow the instructions of the internal wiring diagram for the ± connections of the coil.
- Note that the terminal layout and internal wiring of the surface mount relay are a top view.
- Characteristic data is not guaranteed value but measured values of samples from production line.

1. ROHS COMPLIANCE
All relays produced by Fujitsu Components are compliant with RoHS directive 2011/65/EU including
amendments.
Use of cadmium in electrical contacts is exempted as per Annex III of the RoHS directive 2011/65/EU. Please consider
expiry date of exemption. Relays with cadmium containing contacts are not to be used for new designs.
All relays are lead-free. Please refer to Lead-Free Status Info for older date codes at:
http://www.fujitsu.com/downloads/MICRO/fcai/relays/lead-free-letter.pdf
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 Sn-3.0Ag-0.5Cu.
General information
3. Moisture Sensitivity
SMT versions of FTR-B3 relays in Tape & Reel package will be shipped in Moisture Barrier Bag(MBB).
Moisture Sensitivity Level (MSL) of FTR-B3 relay is indicated on the packing caution label.
Relays must be stored in the unopened MBB at storage conditions <40C/90%RH for a maximum 1 year
SMT versions of FTR-B3 relays in tube packing will not be shipped in MBB. Therefore, these relays shall be dried by
baking before reflow soldering process according to IPC/JEDEC J-STD-033.
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.
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
after soldering
Solder by Soldering Iron:

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 through hole relays.
・
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.
Cautions for latching relays
・
Latching relays are shipped in the state set, but state may change due to shock during transportation or mounting. Before
using the relays, it is advisable to bring the relays in necessary state (set or reset) and program a circuit sequence.
Otherwise, it will or will not operate simultaneously with power activation.
・Please connect relay coils according to specified polarity.
・
Do not apply voltage to both set coil and reset coil at a time.
