Description:
2F Thermal Cutoff Fuse Resistors (Resistance fuses) are
similar in material and structure to fuses.Fuse resistors have two
functions.They are usually used as resistors.If the current is
abnormal, they can act as fuses to protect machinery and
equipment.Cost reduction due to dual function.Fuse resistance can
be divided into: metal film fuse resistance, fuse winding
resistance and fuse cement resistance.Power: 1/4 w, 1/2 w, 1W,
2W.With the increase of power, the appearance size of the product
will continue to increase.Working principle of resistance fuse:
there are fast acting fuse and slow bow fuse.The resistance of
the fuse resistor is usually small, mostly less than 1 ohm.It often
ACTS as a sampling resistor in the circuit.It also protects the
circuit when surges or other large currents occur.A fuse protects
the circuit breaker.
