Film Resistor Element
Meiwa provides low resistance metallic film elements with high thermal resistance or fusing resistor elements with high fusing function, backed up by superior plating technology. Both electrical and non-electrical plating are available.

In case of the same resistance value, the film thickness of our products has a tendency to be some more thin than that of our competitors. However there are no problems about film strength. Besides the chemistry is right between our film and a cutter knife. Therefore we can get a result of causing less damage against our film and the cutter knife.

Kind of film

  Cu-Ni, Ni-P, Ni-Cu-P, e.t.c. Pb-free

Specifications

Appearance No abnormalities (flaw, peering, stain, pin hole, irregularity, blister, crack, etc.)
Film strength No film peering after the cutter test
Characteristics Meets electric performance of fuse resistor and carbon film resistor and metal oxide film resistor and metal film resistor
