Alpha Electronics
Since its founding in 1978, Alpha Electronics has been manufacturing precision resistors using unmatched bulk metal foil technology, and the ultra-precision metal foil ultra-precision resistors with overwhelming performance are resistors made by bonding flat rolled nickel-chromium alloy base metal foil to a smooth ceramic substrate. The metal foil ultra-precision resistors have a minimum temperature coefficient of resistance (TCR) of 0.14 ppm/C typical, a minimum resistance tolerance of 0.005%, and excellent long-term stability of 5 ppm/year and 10 ppm/3 years.
