4308H-101-105 Description

The 4308H-101-105 from Bourns Inc. is a high-performance 7-resistor bussed network designed for precision applications. Housed in an 8-pin SIP (Single Inline Package), it offers a compact footprint of 0.784" x 0.085" (19.91mm x 2.16mm) with a seated height of 0.350" (8.89mm), making it suitable for space-constrained designs. Each resistor provides a 1MΩ resistance with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The 300mW power rating per element and 50ppm/°C resistor-ratio drift further enhance reliability in demanding circuits.
