L083S221LF

L083S221LF Description

The L083S221LF from TT Electronics/IRC is a high-performance thick-film resistor network designed for precision applications requiring stable resistance values under varying conditions. This 4-resistor isolated network features a 220Ω resistance per element with a tight 2% tolerance and a ±100ppm/°C temperature coefficient, ensuring reliable performance across a -55°C to +125°C range. Encased in a conformal-coated SIP package, it offers 0.8W total power dissipation (0.2W per resistor) and supports 100V maximum voltage rating, making it suitable for demanding circuits. The 8-pin through-hole design with 2.54mm terminal pitch ensures easy PCB integration, while its RoHS compliance (with exemption) aligns with environmental standards.
