4309R-101-151LF

4309R-101-151LF Description

The 4309R-101-151LF 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 150Ω 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 under thermal stress. With a power rating of 200mW per element and a REACH Affected/RoHS3 Compliant status, it balances reliability with environmental compliance. Its 0.884" x 0.085" (22.45mm x 2.16mm) footprint and 4.95mm height suit space-constrained designs.

4309R-101-151LF Features

• High Density: Integrates 8 resistors in a single SIP package, reducing PCB space and assembly complexity.
• Stable Performance: Low 50ppm/°C resistor-ratio drift and ±100ppm/°C TCR ensure minimal resistance variation across temperature fluctuations.
• Robust Construction: Through-hole mounting provides mechanical durability, ideal for harsh environments.
• Compliance: Meets ROHS3 and REACH standards, aligning with global environmental regulations.
• Wide Compatibility: EAR99/ECCN classification simplifies export compliance for international shipments.
