4309R-101-182LF Description

The 4309R-101-182LF from Bourns Inc. is an 8-resistor bussed network array housed in a compact 9-pin SIP (Single Inline Package). Designed for through-hole mounting, it features a 1.8kΩ resistance per element with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. With a 200mW power rating per resistor and a 50ppm/°C resistor-ratio drift, this component is engineered for precision and reliability in demanding circuits. Its ROHS3 compliance and REACH Affected status align with modern environmental standards, while its Not Applicable MSL rating simplifies handling and storage.

4309R-101-182LF 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 designs with constrained layouts.
• Robust Performance: Bussed circuit topology simplifies design by connecting resistors in a common configuration, reducing wiring complexity.
• Thermal Stability: Low ±100ppm/°C TCR and 50ppm/°C ratio drift minimize resistance variations under thermal stress.
• Durability: Through-hole construction ensures mechanical stability, while the tube packaging protects during shipping and assembly.
• Industry Compliance: Meets EAR99 and HTSUS 8533.21.0050 classifications for global trade compatibility.
