4420P-1-101

4420P-1-101 Description

The 4420P-1-101 from Bourns Inc. is a high-performance 10-resistor isolated network designed for precision surface-mount applications. Encased in a compact 20-pin SOIC package (12.95mm × 7.50mm), it offers a 100Ω resistance per element with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The array operates at 160mW power per element and features a 50ppm/°C resistor-ratio drift, making it ideal for circuits requiring matched resistance values. Compliant with REACH and ECCN EAR99, it is packaged in Tape & Reel (TR) for automated assembly efficiency.

4420P-1-101 Features

• Precision Network: 10 isolated resistors with 100Ω resistance and ±2% tolerance for consistent performance.
• Stable Thermal Performance: Low ±100ppm/°C TCR and 50ppm/°C ratio drift minimize resistance variation with temperature fluctuations.
• Compact Design: 0.114" (2.90mm) profile and 0.510" × 0.295" footprint save PCB space in dense layouts.
• High Reliability: MSL 1 (Unlimited) moisture sensitivity ensures durability in humid environments.
• Automation-Friendly: Tape & Reel packaging streamlines high-volume SMT assembly.
