4611X-101-121LF Description

The 4611X-101-121LF from Bourns Inc. is a high-performance 10-resistor bussed network designed for precision applications in through-hole mounting configurations. Part of the 4600X series, this SIP (Single In-line Package) network features a compact footprint of 1.098" L × 0.098" W (27.89mm × 2.49mm) with a seated height of 0.200" (5.08mm), making it suitable for space-constrained PCB designs. Each resistor offers a 120Ω resistance with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The 200mW power rating per element and 50ppm/°C resistor-ratio drift further enhance reliability in demanding circuits.
