4608X-101-121

4608X-101-121 Description

The 4608X-101-121 is a 7-resistor bussed network from Bourns Inc.'s 4600X series, designed for through-hole mounting in compact electronic assemblies. This obsolete but reliable component features a 120Ω resistance per element with a tight ±2% tolerance, ensuring consistent performance in precision circuits. Its ±100ppm/°C temperature coefficient provides stable operation across varying thermal conditions. Encased in a 8-pin SIP package with dimensions of 0.798" x 0.098" (20.27mm x 2.49mm) and a 5.08mm seated height, it balances space efficiency with robust 200mW power handling per resistor. The REACH-unaffected design and MSL: Not Applicable rating make it suitable for legacy or low-risk environmental applications.

4608X-101-121 Features

• Bussed Circuit Configuration: Simplifies PCB layout by connecting resistors in a common-node topology.
• High Power Handling: 200mW per resistor outperforms many thin-film arrays in power dissipation.
• Stable Tolerance & TCR: ±2% tolerance and ±100ppm/°C ensure reliability in analog signal conditioning.
• Through-Hole Durability: Robust 8-pin SIP package resists mechanical stress in industrial environments.
• Legacy Compatibility: Ideal for servicing older equipment due to obsolete status but retained performance.
