4605M-101-121LF Description

The 4605M-101-121LF from Bourns Inc. is a high-performance 4-resistor bussed network designed for precision applications in electronic circuits. This through-hole-mounted device features a compact 5-pin SIP (Single In-Line Package) with a 120Ω resistance per element and a tight ±2% tolerance, ensuring reliable signal integrity and minimal deviation. Its ±100ppm/°C temperature coefficient and 50ppm/°C resistor-ratio drift enhance stability across varying thermal conditions, making it suitable for environments requiring consistent performance. The 250mW power rating per element and ROHS3/REACH compliance further underscore its suitability for modern, eco-conscious designs.

4605M-101-121LF Features

• Bussed Circuit Configuration: Simplifies PCB layout by sharing a common node, reducing wiring complexity.
• Robust Construction: Seated height of 6.35mm (0.250") and dimensions of 12.65mm x 2.49mm (0.498" x 0.098") ensure compatibility with standard through-hole designs.
• Low Drift & High Stability: 50ppm/°C resistor-ratio drift minimizes performance variance under thermal stress.
• Wide Operating Range: EAR99/ECCN classification and non-MSAL (Not Applicable) moisture sensitivity enable use in industrial and commercial applications.
• Bulk Packaging: Facilitates efficient handling and assembly in high-volume production.
