Product Name : FLAMEPROOF FUSIBLE RESISTORS
Description
INTRODUCTION:
FMF series is a low cost type resistor provides circuit protection for overload or component failure. The resistor will be opened quickly under continuous load, it prevents circuit board from damage and fire hazards.
FEATURES:
- Suitable to apply in transistor protection circuit.
- Small in sizes with low cost.
- Noncombustible insulating coat, solvent proof and excellent application in high temperature.
- Good TCR±100ppm/℃
- Uniform in fusing time
