THIN FILM CHIP RESISTORS 

Epak Electronics Ltd offer the complete range of Mini-Systems Inc (MSI) Thin Film Resistors.

Thin film resistors are manufactured using sputtering technology to apply the resistive "film" and they are then etched using a process similar to making printed circuit boards. The the surface is coated with a photo-sensitive material, covered by a film, irradiated with ultraviolet light, and then the exposed photo-sensitive coating, and underlying thin film, are etched. Mini Systems use a laser trimming system to accurately manufacture the parts to the exact value required.

Depending on the series, typical values range upwards of 2 Ohms up to 1 Meg Ohm and tolerances range from 0.1% to 10%. The substrate metal is typically Alumina or Aluminum Nitride and with a range of termination pads from no solder to Indium and high temperature solders, RoHS compliant solders are now also available on request.
