4309R-101-392

4309R-101-392 Description

The 4309R-101-392 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 3.9kΩ resistance per element with a tight ±2% tolerance, ensuring precision in circuit design. The array operates within a ±100ppm/°C temperature coefficient and offers a 50ppm/°C resistor-ratio drift, making it stable under thermal stress. With a 200mW power rating per element and a REACH-compliant construction, this component is engineered for reliability in demanding environments. Its non-MSL (Moisture Sensitivity Level) rating simplifies handling and storage.

4309R-101-392 Features

• High-Density Integration: Combines 8 resistors in a space-saving 0.884" x 0.085" (22.45mm x 2.16mm) footprint, ideal for PCB-constrained designs.
• Robust Performance: ±2% tolerance and low TCR (±100ppm/°C) ensure consistent signal integrity.
• Thermal Stability: 50ppm/°C resistor-ratio drift minimizes performance variance across temperature fluctuations.
• Simplified Assembly: Through-hole SIP package with 9 pins for easy soldering and mechanical durability.
• Compliance: Meets EAR99 and HTSUS 8533.21.0050 standards, suitable for global export.

4309R-101-392 Applications
