4310H-101-331 Description

The 4310H-101-331 from Bourns Inc. is a high-performance 9-resistor bussed network designed for precision applications in electronic circuits. Housed in a 10-pin SIP (Single In-Line Package), this array offers a 330Ω resistance per element with a tight ±2% tolerance, ensuring reliable signal conditioning and voltage division. Its compact 0.984" x 0.085" (24.99mm x 2.16mm) footprint and 0.350" (8.89mm) height make it suitable for space-constrained designs. The device operates with a 300mW power rating per resistor and features a ±100ppm/°C temperature coefficient, minimizing resistance drift across temperature variations. Compliant with REACH and EAR99 regulations, it is packaged in tubes for automated assembly.

4310H-101-331 Features

• Bussed Circuit Topology: Simplifies PCB layout by connecting resistors in a common-node configuration.
• Low Resistor-Ratio Drift (50ppm/°C): Ensures stable performance in temperature-sensitive environments.
• High Power Handling (300mW/Element): Supports demanding applications without derating concerns.
• Through-Hole Mounting: Robust mechanical stability for industrial and automotive systems.
• Wide Operating Temperature Range: Reliable performance under harsh conditions.
• MSL Not Applicable: Eliminates moisture sensitivity issues during storage and assembly.
