4310M-102-121 Description

The 4310M-102-121 from Bourns Inc. is a high-performance resistor network designed for precision applications in electronic circuits. This through-hole mounted device features 5 isolated resistors, each with a resistance of 120 ohms and a tight tolerance of ±2%, ensuring consistent performance in demanding environments. The network operates within a ±100ppm/°C temperature coefficient, with a low resistor-ratio drift of 50ppm/°C, making it ideal for stable signal conditioning and voltage division. Encased in a compact 10-pin SIP package with dimensions of 0.984" x 0.085" (24.99mm x 2.16mm) and a seated height of 0.250" (6.35mm), it is suitable for space-constrained designs. The 400mW power rating per element and REACH compliance further enhance its reliability for industrial use.
