Product Description

WK73S Wide Terminal Type Flat Chip Resistors (Low Resistance)

The WK73S series are wide-side termination (reverse-geometry) type flat chip resistors designed for low resistance applications. These resistors offer high reliability and performance with a T.C.R. of 100 x 10^-6/K and resistance tolerance options as tight as 0.5%. They are suitable for both reflow and flow solderings and meet EU RoHS requirements for lead-free terminations. These resistors are AEC-Q200 tested, making them suitable for demanding automotive and industrial applications.
