Fuse Resistors

Fuse Resistors, Metal Film Fuse Resistors

1, Low temperature coefficient, high precision,low noise and good high frequency performance.

2,Can be Fusible during the stated time for protecting the circuit once wording at the required overload voltage.

3, Operating ambient temperature:-55 to +125.

4, The surface is brick red nonflammable coating and indicate a white ring at the behind of the precision color ring.

5, Resistance tolerance:±5%,±10%.
