Lineup of various chip resistors for highly reliable applications such as automotives 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. As the reliability test ⊿R shows extremely high accuracy of ± 0.1% (RN73R is ± 0.1% to ± 0.25%), the products achieve minimal current noise, and improved moisture resistance by applying a special protective film. AEC-Q200 tested.
The thick film type highly reliable chip resistor RS73 series has 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 resistance value tolerance of ± 0.25% and resistance temperature coefficient of ± 50 x 10⁻⁶ / K.

KOA's thick-film chip resistors have high performance and environmental resistance, used in a wide range of electronic devices.
SG73S/P series has excellent surge resistance, pulse resistance, and guarantees higher rated power than normal products. Our various lineup includes HV73 series that has a higher maximum working voltage and is suitable for high voltage use, as well as wide terminal type WK73 series with a power guarantee (0.33W to 3W).

We have a large selection of shunt resistors ideal for motor control, various power supplies such as inverters, power supply management for batteries, and overcurrent applications.
TLR series applies the unique non-trimming structure to achieve low inductance and enables accurate current detection. Size lineup includes 6332 size offering 3W, 2012 size with high power 1W type and high accuracy with T.C.R.50x10⁻⁶/K type is also available.
We have a wide variety of products such as low resistance (10mΩ ~), low T.C.R (75 × 10⁻⁶/K ~) and UR73 series suitable for high precision current detection.

We have a variety of lead wire type resistors, less supported by manufacturers in Japan.
