WK73S2BTTD3R30F Description

Short technical summary and product information.

This KOA Speer WK73S2BTTD3R30F is a wide terminal type flat chip resistor from the WK73S series. It features a nominal resistance of 3.3 Ohms with a tight tolerance of ±1% and a power rating of 0.75W (3/4W). The resistor operates within a temperature range of -55°C to 155°C and has a temperature coefficient of ±100ppm/°C.

 

Designed for reliability, this component is AEC-Q200 tested and features moisture-resistant properties. Its thick film composition and wide-side termination make it suitable for both reflow and flow solderings. The component comes in a 1206 (3216 Metric) or 0612 package size, with dimensions of 1.60mm in length and 3.20mm in width, and a height of 0.70mm.

 

Products with lead-free terminations meet EU RoHS requirements. This resistor is ideal for applications requiring high reliability and performance in a compact surface-mount form factor.
