4609X-AP1-273LF Description

The 4609X-AP1-273LF from Bourns Inc. is a high-performance 8-resistor bussed network designed for precision applications. With a 27kΩ resistance per element and a tight ±2% tolerance, this through-hole-mounted array ensures reliable signal conditioning and voltage division. Its ±100ppm/°C temperature coefficient guarantees stable performance across varying thermal conditions, making it suitable for environments with fluctuating temperatures. The device features a 9-pin SIP configuration and a compact footprint of 22.81mm x 2.49mm, balancing space efficiency with robust power handling (200mW per element). Packaged in Tape & Box (TB), it is ideal for automated assembly processes.
