4309R-101-271 Description

The 4309R-101-271 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 resistance value of 270Ω per element with a tight tolerance of ±2%, ensuring consistent performance in precision circuits. The array operates within a ±100ppm/°C temperature coefficient and offers a resistor-ratio drift of 50ppm/°C, making it stable across varying thermal conditions. With a 200mW power rating per resistor and a REACH-compliant construction, this component is ideal for industrial and commercial applications requiring reliability and durability.

4309R-101-271 Features

• High-Density Integration: Combines 8 resistors in a space-saving 0.884" x 0.085" (22.45mm x 2.16mm) footprint, reducing PCB clutter.
• Stable Performance: Low ±100ppm/°C TCR and 50ppm/°C ratio drift ensure minimal resistance variation under thermal stress.
• Robust Construction: Through-hole design with a 0.195" (4.95mm) seated height for secure mounting in harsh environments.
• Wide Compatibility: EAR99/ECCN and HTSUS 8533.21.0050 classifications facilitate global supply chain integration.
• Reliable Power Handling: 200mW per resistor supports moderate power applications without derating concerns.
