4310R-104-221/271L

4310R-104-221/271L Description

The 4310R-104-221/271L from Bourns Inc. is a high-performance 16-resistor network designed for precision applications in electronic circuits. Housed in a 10-pin SIP (Single In-Line Package), this through-hole-mount component features dual terminations with resistances of 220Ω and 270Ω, offering a ±2% tolerance and a ±100ppm/°C temperature coefficient. With a compact footprint of 0.984" x 0.085" (24.99mm x 2.16mm) and a low resistor-ratio drift of 50ppm/°C, it ensures stable performance in varying thermal conditions. The 200mW power rating per element and ROHS3/REACH compliance make it suitable for modern, environmentally conscious designs.
