Platinum Resistance Temperature Detector M-FK 1020
F series PRTDs are designed for large volume applications where long term
stability, interchangeability and accuracy over a large temperature range are
vital. Typical applications are Automotive, White Goods, HVAC, Energy Man-
agement, Medical and Industrial equipment.

Tolerance class A - 30 °C to + 350 °C
Tolerance class 1/3 B 0 °C to + 100 °C
Temperature coefficient : Tc = 3850 ppm/K
Leads : platinum clad nickel wire
Longterm stability : max. R
