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.

KOA's thick-film chip resistors have high performance and environmental resistance, those are used in a wide range of electronic devices.
The SG73S/P series has excellent surge resistance, pulse resistance, and guarantees higher rated power than normal products. The HV73 long side electrode type series has a higher maximum working voltage and is suitable for high voltage use and high heat dissipation type . We have various lineup such as the WK73 series with a power guarantee (0.33W to 3W).

We have a large selection of shunt resistors that are ideal for motor control, various power supplies such as inverters, power supply management for batteries, and overcurrent applications.
The TLR series uses the company's unique non-trimming structure to achieve low inductance and enable accurate current detection. 6332 size 3W-2012 size 1W compact high power, high accuracy with T.C.R.50x10^-6/K.
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 resistors with leads that are less supported by manufacturers in Japan.
