4310H-101-221 Description

The 4310H-101-221 from Bourns Inc. is a high-performance 9-resistor bussed network designed for precision applications in electronic circuits. With a 220Ω resistance per element and a tight ±2% tolerance, this through-hole-mounted array ensures reliable signal conditioning and voltage division. Its ±100ppm/°C temperature coefficient and 50ppm/°C resistor-ratio drift guarantee stable performance across varying environmental conditions. The compact 0.984" x 0.085" (24.99mm x 2.16mm) footprint and 0.350" (8.89mm) height make it suitable for space-constrained designs. Packaged in a tube, this 10-pin SIP device is part of Bourns' 4300H series, known for robustness and consistency.
