4606X-101-203 Description

The 4606X-101-203 from Bourns Inc. is a 5-resistor bussed network housed in a 6-pin SIP (Single In-line Package) configuration. Designed for through-hole mounting, this array offers a 20kΩ resistance per element with a tight ±2% tolerance, ensuring reliable performance in precision circuits. Its compact 0.598" x 0.098" (15.19mm x 2.49mm) footprint and 5.08mm seated height make it suitable for space-constrained applications. The ±100ppm/°C temperature coefficient enhances stability across operating conditions, while the 200mW power rating per resistor balances efficiency and durability. Although marked Obsolete, it remains REACH compliant and MSL-exempt, ideal for legacy designs or non-lead-free applications.
