4308R-101-511LF

4308R-101-511LF Description

The 4308R-101-511LF from Bourns Inc. is a high-performance 7-resistor bussed network housed in an 8-pin SIP (Single In-line Package) configuration. Designed for through-hole mounting, this resistor array offers a 510Ω resistance per element with a tight ±2% tolerance, ensuring reliable signal conditioning and voltage division in precision circuits. Its compact dimensions (19.91mm x 2.16mm) and low-profile design (4.95mm max height) make it suitable for space-constrained applications. The device operates within a ±100ppm/°C temperature coefficient range, with a 50ppm/°C resistor-ratio drift, ensuring stability across varying environmental conditions.

4308R-101-511LF Features

• Bussed Circuit Topology: Simplifies PCB layout by connecting resistors in a common-node configuration.
• High Power Handling: 200mW per resistor enables robust performance in power-sensitive designs.
• RoHS3 & REACH Compliance: Meets stringent environmental and safety standards.
• Wide Operating Range: Stable performance across industrial temperature ranges due to low TCR and ratio drift.
• Non-MSIL (Moisture Sensitivity Level): Ideal for applications requiring extended shelf life or harsh environments.
• Tube Packaging: Ensures safe handling and automated assembly compatibility.

4308R-101-511LF Applications
