4608X-102-221 Description

The 4608X-102-221 from Bourns Inc. is a 4-resistor network in an 8-pin SIP (Single In-line Package), designed for through-hole mounting. This obsolete yet reliable component features 220Ω resistance per element with a tight ±2% tolerance, ensuring consistent performance in precision circuits. Its isolated circuit type allows independent resistor operation, making it versatile for diverse designs. The network operates within a ±100ppm/°C temperature coefficient, maintaining stability across varying thermal conditions. Encased in a compact 20.27mm x 2.49mm (0.798" x 0.098") footprint and a 5.08mm (0.200") height, it suits space-constrained applications. Rated at 300mW power per element, it balances power handling and miniaturization.
