High Precision Chip Resistor

Lineup of various chip resistors for highly reliable applications such as in-vehicle and industrial equipment
Thin-film type metal film resistors RN73H and RN73R support a standard high-precision resistance tolerance: ± 0.05% and temperature coefficient of resistance: ± 5 × 10−6 / K. The reliability test ⊿R has a extremely high accuracy of ± 0.1% (RN73R is ± 0.1% to ± 0.25%), minimal current noise, and improved moisture resistance by using a special protective film. Compatible with AEC-Q200. The thick film type highly reliable chip resistor RS73 series has a high accuracy (resistance value tolerance ± 0.1% ~, temperature coefficient of resistance ± 25 × 10−6 / K ~) and excellent long-term stability (⊿R of reliability test is ± 0.2% ~ ± 0.5%). The ultra-precision class chip resistor RK73G series is a high-precision product with a resistance value tolerance of ± 0.25% and a resistance temperature coefficient of ± 50 x 10−6 / K.
