L101S103LF

L101S103LF Description

The L101S103LF from TT Electronics/Welwyn is a high-reliability thick-film resistor network designed for precision applications. It features a 10KΩ resistance per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Encased in a conformal-coated SIP (Single In-line Package), this 9-resistor network offers a 1W total power rating (0.125W per resistor) and supports 100V maximum voltage, making it suitable for demanding industrial and commercial circuits. The 10-pin through-hole design with a 2.54mm terminal pitch ensures easy PCB integration, while its bulk packaging optimizes cost-efficiency for volume production.
