WU73 from KOA – Wide Terminal Type with Low TCR

KOA is now offering the WU732B as an expansion of the WK73 series. This low-ohm resistor with wide terminals offers a power rating of 1 W in a 0612 package size with 1% tolerance. Manufactured using thick-film technology, this type is available in a resistance range from 10 mOhm to 100 mOhm. A key feature is the improved temperature coefficient. A TCR of 150 is specified for 10 to 12 mOhm, and a TCR of 100 for 13 to 100 mOhm. The temperature range is specified from -55 to +155°C, with derating starting at 105°C (terminal temperature). The component meets AEC-Q200 requirements.

The WK73 series is available in package sizes 0612 to 1225, with power ratings from 0.75 to 2 W. A distinction is made between the value ranges of 10 mOhm to 9.76 Ohm (WK73S) and 10 Ohm to 1 MOhm (WK73R). The series is available in tolerances of 1% and 5%, and the temperature range also extends from -55 to +155°C. All package sizes are tested according to AEC-Q200. The entire series is also available in a special anti-sulfuration version, the WK73-RT.
