4309R-101-394

4309R-101-394 Description

The 4309R-101-394 from Bourns Inc. is an 8-resistor bussed network array designed for precision through-hole applications. With a resistance value of 390kΩ per element and a tight tolerance of ±2%, this component ensures reliable performance in demanding circuits. The array operates within a ±100ppm/°C temperature coefficient, complemented by a low resistor-ratio drift of 50ppm/°C, making it stable across varying environmental conditions. Packaged in a 9-pin SIP (Single In-line Package) with compact dimensions of 22.45mm x 2.16mm, it balances space efficiency with robust 200mW power handling per resistor.

4309R-101-394 Features

• High-Density Integration: Combines 8 resistors in a single SIP package, reducing board space and assembly complexity.
• Stable Performance: Low ±100ppm/°C TCR and 50ppm/°C ratio drift ensure minimal resistance variation under thermal stress.
• Through-Hole Reliability: Robust construction suits industrial and automotive environments where vibration resistance is critical.
• Wide Compatibility: REACH Affected but EAR99/ECCN compliant, facilitating global supply chain integration.
• Non-MSIL Rated: Ideal for applications where moisture sensitivity is not a constraint.
