4309R-101-471 Description

The 4309R-101-471 from Bourns Inc. is an 8-resistor bussed network array designed for precision through-hole applications. With a compact 0.884" x 0.085" (22.45mm x 2.16mm) footprint and a low-profile 0.195" (4.95mm) height, it integrates eight 470Ω resistors with a tight ±2% tolerance and a stable ±100ppm/°C temperature coefficient. The device operates at 200mW power per element and features a 9-pin SIP configuration, housed in a tube package for secure handling. Its 50ppm/°C resistor-ratio drift ensures consistent performance in varying thermal conditions, making it ideal for analog and digital circuits requiring reliable resistance matching.

4309R-101-471 Features

• High-Density Integration: Combines eight 470Ω resistors in a space-saving SIP package, reducing PCB footprint.
• Stable Performance: Low ±100ppm/°C TCR and 50ppm/°C ratio drift minimize resistance variations under thermal stress.
• Robust Construction: Through-hole mounting ensures mechanical durability for industrial environments.
• Wide Compatibility: REACH Affected and EAR99/ECCN compliant, suitable for global supply chains.
• Simplified Design: Bussed circuit topology streamlines layout in voltage divider or pull-up/down networks.
