4609X-101-820LF Description

The 4609X-101-820LF from Bourns Inc. is an 8-resistor bussed network array housed in a compact 9-pin SIP (Single In-line Package). Designed for through-hole mounting, it features a resistance value of 82Ω per element with a tight tolerance of ±2%, ensuring reliable performance in precision circuits. The array operates within a ±100ppm/°C temperature coefficient, making it stable across varying environmental conditions. With a 200mW power rating per resistor and a 5.08mm max seated height, it balances power handling and space efficiency. The device is ROHS3 compliant and REACH unaffected, meeting stringent environmental standards.

4609X-101-820LF Features

• High-Density Integration: Combines 8 resistors in a 22.81mm x 2.49mm footprint, reducing PCB space.
• Bussed Circuit Design: Simplifies layout by connecting resistors in a common configuration, ideal for pull-up/pull-down networks.
