4308R-101-472 Description

The 4308R-101-472 from Bourns Inc. is a high-performance 7-resistor bussed network housed in an 8-pin SIP (Single In-line Package). Designed for through-hole mounting, it features a compact footprint of 0.784" x 0.085" (19.91mm x 2.16mm) and a seated height of 0.195" (4.95mm), making it suitable for space-constrained applications. Each resistor offers a 4.7kΩ 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 precision circuits.
