4608X-102-821 Description

The 4608X-102-821 from Bourns Inc. is a high-performance resistor network designed for precision applications in electronic circuits. This 4-resistor array features isolated resistors, each with a resistance value of 820Ω and a tight tolerance of ±2%, ensuring consistent performance in demanding environments. Encased in an 8-pin SIP (Single Inline Package) with a compact footprint of 0.798" x 0.098" (20.27mm x 2.49mm), it offers a space-efficient solution for through-hole mounting. The device operates with a power rating of 300mW per element and maintains stability across temperature variations, thanks to its ±100ppm/°C temperature coefficient.

4608X-102-821 Features

• Precision Resistance: Four isolated 820Ω resistors with ±2% tolerance for reliable signal conditioning.
• Robust Construction: Through-hole mounting ensures mechanical durability in harsh environments.
• Thermal Stability: Low ±100ppm/°C temperature coefficient minimizes resistance drift.
