4420P-T02-273 Description

The 4420P-T02-273 from Bourns Inc. is a high-performance 19-resistor bussed network designed for precision surface-mount applications. With a 27kΩ resistance per element and a tight ±2% tolerance, this device ensures reliable signal conditioning and voltage division in compact PCB layouts. Its ±100ppm/°C temperature coefficient and 50ppm/°C resistor-ratio drift provide stable performance across varying environmental conditions. Housed in a 20-pin SOIC package (12.95mm × 7.50mm × 2.90mm), it combines space efficiency with 160mW power dissipation per element, making it suitable for densely populated boards. Compliant with REACH and EAR99 regulations, it meets stringent industry standards for environmental and export compliance.
