KOA UR73V Low-Ohm Series – Wider Resistance Range, Improved Heat Resistance

KOA now offers its thick film low-ohm UR73V series in size 1206 with a significantly extended value range. While the resistance range previously extended from 10 mOhm to 100 mOhm, the UR73VH2B now allows for 10 mOhm to 1 Ohm. Furthermore, the terminal temperature at which derating begins has been increased from 95°C to 125°C (Ambient Temperature: 70°C). The rated power is also exceptional for a thick film resistor in size 1206, at 1 Watt. The TCR is specified as 100 ppm/K.

The UR73(V) series is available in a non-automotive version (UR73) and an automotive version (UR73V). The UR73 is available in sizes 0402 to 2512 with rated powers from 0.125 Watt to 1 Watt. The value range extends from 10 mOhm to 100 mOhm.
The UR73V is available in sizes 0805 and 1206, with powers of 0.5 Watt and 1 Watt. The value range extends from 10 mOhm to 100 mOhm, and up to 1 Ohm for the UR73VH2B. Naturally, the UR73V complies with AEC-Q200 requirements.
