Definition of Terms

Rated Functioning Temperature (Tf)
Rated functioning temperature is the operating temperature of the thermal link, measured using the method specified in the
safety standard.
As stated in the Electrical Appliance and Material Safety Law (PSE) of Japan (Appendix 3, Section 3), the thermal links should
operate within ±7°C of the specified operating temperature. In cases where Tf is greater than 200°C, the thermal links
should operate within ±10°C of the specified operating temperature.
In standards that comply with the IEC standard, it is indicated that the thermal links should operate within +0/-10°C of the
specified temperature range.

Lead Cutting

Lead Forming (SF/R, SFH/R)

Packing Quantity

Lead wire process

If using a SF-type thermal link, the lead on the resin-sealed side must not be allowed to touch the case. This would cause the
current to flow from the lead on the resin-sealed side to the opposite lead resulting in a non-functioning thermal link.
