4608X-101-101 Description

The 4608X-101-101 from Bourns Inc. is a 7-resistor bussed network housed in an 8-pin SIP (Single In-line Package) configuration, designed for through-hole mounting. With a 100Ω resistance per element and a ±2% tolerance, this array ensures reliable performance in precision circuits. The device operates within a ±100ppm/°C temperature coefficient, making it stable across varying thermal conditions. Its compact 0.798" x 0.098" (20.27mm x 2.49mm) footprint and 5.08mm seated height allow for efficient PCB space utilization. Rated at 200mW power per element, it balances power handling with miniaturization. The REACH-unaffected, obsolete status indicates compliance with environmental regulations but limited availability for new designs.

4608X-101-101 Features

• Bussed Circuit Topology: Simplifies design by connecting resistors in a common configuration, reducing wiring complexity.
• High Power Handling: 200mW per resistor supports moderate power applications without derating concerns.
• Stable Performance: ±100ppm/°C TCR ensures minimal resistance drift under thermal stress.
