4606X-102-121 Description

The 4606X-102-121 from Bourns Inc. is a 3-resistor isolated network designed for precision through-hole applications. With a 120Ω resistance per element and a tight ±2% tolerance, this device ensures reliable performance in demanding circuits. Its ±100ppm/°C temperature coefficient enhances stability across varying thermal conditions. Encased in a compact 6-pin SIP package (15.19mm x 2.49mm), it features a 300mW power rating per resistor, making it suitable for moderate-power applications. The 4600X series is known for robustness, though this model is marked Obsolete, it remains relevant for legacy designs due to its REACH Unaffected compliance and Not Applicable MSL rating.

4606X-102-121 Features
