New WK73 Wide Terminal Resistor Ideal for High Power Applications
Bradford, PA - July 12, 2007 - KOA Speer Electronics introduces the WK73 wide terminal flat chip resistor providing high reliability and performance. This new flat chip resistor features higher power ratings as a result of its enhanced heat dissipation, as demonstrated by the WK73S3A type (1225 size) with a 1.5W rating vs. KOA Speer's RK73B3A type (2512 size) with a 1W rating. The WK73 offers current sensing for power supply circuits, which makes it ideal for automotive electronics, ECU's, anti-locking braking systems and air bag systems.
Its wide terminal construction gives the WK73 resistor superior thermal shock characteristics and high solder joint reliability. The resistance range of the WK73 is 22mW ~ 1MW and the T.C.R. is ±100, ±200, ±300, & ±800ppm/°C. The available tolerances are ±1% & ±5% with a high power rating of 1.0W & 1.5W @ 70°C. This wide terminal flat chip resistor sizes include 1020, 1218 & 1225 and it is RoHS Compliant.
Typical lead time is 10 weeks, packaging: 4,000 pcs/7" embossed plastic with small quantity pricing at $0.50 each. Samples and sample kits are available upon request.
