4309R-101-472LF Description

The 4309R-101-472LF from Bourns Inc. is an 8-resistor bussed network array housed in a compact 9-pin SIP (Single In-Line Package). Designed for through-hole mounting, it features a 4.7kΩ resistance per element with a tight tolerance of ±2% and a low temperature coefficient of ±100ppm/°C, ensuring stable performance across varying environmental conditions. The array operates at 200mW power per element and boasts a resistor-ratio drift of 50ppm/°C, making it suitable for precision applications. Its robust construction includes a RoHS3-compliant, REACH-affected design, and it is packaged in tubes for easy handling.

4309R-101-472LF Features

• High-Density Integration: Combines 8 resistors in a space-saving 0.884" x 0.085" (22.45mm x 2.16mm) footprint, ideal for PCB designs with limited real estate.
• Stable Performance: Low TCR (±100ppm/°C) and resistor-ratio drift (50ppm/°C) ensure minimal resistance variation under thermal stress.
• Reliable Construction: Through-hole mounting provides mechanical stability, while the 0.195" (4.95mm) seated height accommodates standard board layouts.
• Compliance: Meets RoHS3 and REACH standards, with an ECCN of EAR99 and HTSUS 8533.21.0050 for global compatibility.
• Bussed Circuit: Simplifies design by internally connecting resistors, reducing external wiring complexity.
