4608X-101-122 Description

The 4608X-101-122 is a 7-resistor bussed network from Bourns Inc.'s 4600X series, designed for through-hole mounting in compact electronic assemblies. With a 1.2kΩ resistance per element and a ±2% tolerance, this array ensures reliable performance in precision circuits. Its ±100ppm/°C temperature coefficient provides stability across varying thermal conditions, while the 200mW power rating per resistor balances efficiency and durability. The 8-pin SIP (Single In-line Package) configuration and 0.798" × 0.098" (20.27mm × 2.49mm) footprint make it suitable for space-constrained layouts. Although marked Obsolete, it remains REACH-compliant and MSL-exempt, ensuring compatibility with legacy designs.
