WK73 from KOA – High Power Thick Film Wide Terminal Type

KOA now offers a more powerful version of its proven WK73 series. Based on the concept of Terminal Part Temperature, rated powers of 1.5 Watts (size 0612), 2 Watts (size 1020), and 3 Watts (size 1225) are now guaranteed. In all cases, derating starts at 95°C. The special features of this component are excellent temperature distribution, very good cycle stability, and long-term stability. The component can be used in a temperature range from -55 to +155°C, and the resistance range extends from 10 mOhm to 1 MOhm. The WK73 Power up version also complies with the requirements of AEC-Q200.

The standard version of the WK73 series is available in sizes 0204 to 1225, with rated powers from 0.33 to 2 Watts. A distinction is made between resistance ranges of 10 mOhm to 9.76 Ohm (WK73S – only in sizes 0612 – 1225) and 10 Ohm to 1 MOhm (WK73R). The series is offered in 1% and 5% tolerances, and the temperature range here also extends from -55 to +155°C. All sizes are tested according to AEC-Q200. The complete series also exists in a special anti-sulfuration version, WK73-RT.
