L091S471LF

L091S471LF Description

The L091S471LF from TT Electronics / BI Technologies is a high-performance 8-resistor thick film network designed for precision applications. Housed in a conformal coated 9-pin SIP package, it offers a 470Ω resistance per element with a tight 2% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.125W power rating per resistor (0.9W total), a 100V maximum voltage rating, and through-hole pin termination, this network is built for reliability in demanding circuits. Its conformal coating enhances durability against environmental factors, making it suitable for harsh operating conditions.
