4606X-101-181 Description

The 4606X-101-181 is a 5-resistor bussed network from Bourns Inc.'s 4600X series, designed for through-hole mounting in compact electronic assemblies. This obsolete but REACH-unaffected component features a 180Ω resistance per element with a tight ±2% tolerance, ensuring reliable performance in precision circuits. Its ±100ppm/°C temperature coefficient provides stable operation across varying thermal conditions, while the 200mW power rating per resistor balances efficiency and durability. Encased in a 6-pin SIP package with dimensions of 0.598" x 0.098" (15.19mm x 2.49mm) and a 5.08mm seated height, it suits space-constrained designs.

4606X-101-181 Features

• Bussed Circuit Topology: Simplifies PCB layout by connecting resistors in a common-node configuration.
• High Power Handling: 200mW per resistor outperforms many low-power arrays in its class.
• Stable Tolerance & TCR: ±2% tolerance and ±100ppm/°C ensure consistent performance under thermal stress.
• Robust Construction: Through-hole design with Not Applicable MSL rating, ideal for non-humidity-sensitive environments.
• Compact SIP Package: Saves board space while accommodating standard through-hole assembly processes.
