4420P-2-271LF

4420P-2-271LF Description

The 4420P-2-271LF from Bourns Inc. is a high-performance 19-resistor bussed network designed for precision surface-mount applications. Encased in a compact 20-pin SOIC package with dimensions of 0.510" x 0.295" (12.95mm x 7.50mm) and a low-profile height of 0.114" (2.90mm), this resistor array offers a 270Ω resistance per element with a tight ±2% tolerance. Its ±100ppm/°C temperature coefficient and 50ppm/°C resistor-ratio drift ensure stable performance across varying thermal conditions. Compliant with ROHS3 and REACH standards, it is ideal for environmentally conscious designs.

4420P-2-271LF Features

• 19-resistor bussed network with 160mW power rating per element, ensuring robust current handling.
• Surface-mount (SOIC) package for space-constrained PCB layouts.
• Low moisture sensitivity (MSL 1) for extended shelf life and reliability.
• Tape & Reel (TR) packaging for automated assembly efficiency.
• Wide operating temperature range supported by a ±100ppm/°C TCR, outperforming generic arrays in thermal stability.
• 270Ω resistance with ±2% tolerance, ideal for precision voltage division and pull-up/down applications.
