M25SI Overview
Imperial size Metric size code Resistance range Resistance tolerance Temperature coefficient Rated dissipation, P70 (1) Operating voltage, Umax. ACRMS/DC Permissible film temperature, ϑF max. (1) Operating temperature range (1) Permissible voltage against ambient (insulation):.
M25SI Key Features
- Metal film on high quality ceramic
- Special protective top coat
- Flame retardant
- Sn solder contacts on Ni barrier layer
- Fusible resistor for constant voltage
- Material categorization: for definitions of pliance
- 55 °C to 125 °C
- A suitable low thermal resistance of the circuit board assembly must be safeguarded in order to maintain the film temper
