L091S103LF

L091S103LF Description

The L091S103LF from TT Electronics/IRC is a high-performance thick film resistor network designed for precision applications. This 8-resistor bussed (BUS) network features a 10 kΩ resistance value per element with a tight 2% tolerance and a low ±100 ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Encased in a conformal coated SIP (Single In-line Package), it offers robust protection against environmental factors while maintaining a compact footprint (22.86 mm length × 2.5 mm width × 5.08 mm height). Rated for 100 V maximum voltage and 0.9 W total power dissipation (0.125 W per resistor), it is ideal for demanding circuit designs requiring reliability and space efficiency.
