MELF Resistors

Chip Resistors;Small size and light, High Precision Chip Resistors; Melf Resistors; Chip Array Resistors; Array Resistor

1,It can reduce the area and weight of the PCB for its small size and light.

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

3,High credibility:the thick metal film resistor body is added with glass protective layer and three layers of electrode composition.

4,The appearance dimension is symmetrical and accurate for easy assembly.

5,Resistance tolerance: ±0.1%,±0.25%,±0.5%
