4306R-102-124LF Description

The 4306R-102-124LF from Bourns Inc. is a high-performance 3-resistor network designed for precision applications in electronic circuits. Part of the 4300R series, this through-hole-mounted array features 120k Ohm resistance per element with a tight ±2% tolerance, ensuring reliable signal conditioning and voltage division. Its isolated circuit type allows independent operation of each resistor, making it versatile for complex designs. The device operates within a ±100ppm/°C temperature coefficient range, with a low resistor-ratio drift of 50ppm/°C, ensuring stability across varying environmental conditions. Encased in a compact 6-pin SIP package (14.83mm x 2.16mm), it offers a 300mW power rating per element and is RoHS3 compliant, meeting modern environmental standards.

4306R-102-124LF Features

• Precision Resistance: 120k Ohm ±2% tolerance for accurate signal processing.
• Stable Performance: Low TCR (±100ppm/°C) and resistor-ratio drift (50ppm/°C) ensure reliability in temperature-sensitive applications.
• Robust Construction: Through-hole mounting with a 0.195" (4.95mm) max height suits space-constrained PCBs.
• Isolated Design: Independent resistors enable flexible circuit configurations.
