L-10-1S-103-LF Description

The L-10-1S-103-LF from TT Electronics/IRC is a high-performance 10K Ohm thick film resistor network designed for precision applications. This 9-resistor network features a 2% tolerance, ±100ppm/°C temperature coefficient, and a 1W total power rating (0.125W per resistor). Encased in a conformal-coated SIP package, it offers robust protection against environmental factors while maintaining a compact footprint (25.4mm length × 2.5mm depth × 5.08mm height). The 10-pin through-hole design with a 2.54mm terminal pitch ensures easy integration into PCB layouts. Compliant with EU RoHS (with exemption) and rated for 125°C maximum operating temperature, it is ideal for industrial and commercial electronics.
