CSC04B03390RGEK Description

The CSC04B03390RGEK from Vishay is a high-performance thick film resistor network designed for precision isolation applications. This 390 Ohm, 2% tolerance network features two isolated resistors in a 4-pin SIP (Single In-line Package) with conformal coating for enhanced environmental protection. Rated for 0.6W total power dissipation (0.4W per resistor) and operating within a temperature range of 25°C to 150°C, it delivers stable performance in demanding conditions. The device boasts a ±100ppm/°C temperature coefficient, ensuring minimal resistance drift. Its through-hole pin termination and 2.54mm terminal pitch facilitate easy PCB integration, while the 100V maximum voltage rating makes it suitable for medium-voltage circuits.
