KOA Speer WN73H Metal Thin Film Chip Resistors

KOA Speer WN73H Metal Thin Film Chip Resistors are high-power, wide-termination, and high-precision resistors for automotive, medical, and industrial applications. These KOA Speer reverse geometry resistors pack power ratings of 0.3W into a 0603 package and 1W into a 1206 package. Resistance values for the WN73H series range from 10Ω to 100kΩ resistance. These metal thin film resistors also provide high-precision resistance tolerances as low as ±0.1% and a high-performance temperature coefficient of resistance (TCR) down to ±10ppm/°C.
