Y4485V0074BA9R

Y4485V0074BA9R Description

The Y4485V0074BA9R is a high-precision 2-resistor network from VPG Foil Resistors' DSMZ series, designed for voltage divider applications with TCR-matched performance. This surface-mount device (SMD) features ultra-tight tolerances (±0.1% resistance, ±0.05% ratio matching) and an exceptional temperature coefficient of resistance (TCR) of ±0.2ppm/°C, ensuring minimal drift (±0.1ppm/°C ratio drift) across operating conditions. Encased in a compact 1610 package (4.06mm x 2.69mm) with a low profile (1.80mm height), it offers 50mW power handling per element and is available in 1kΩ and 5kΩ resistance values. Compliant with RoHS3 and rated MSL 1 (unlimited shelf life), it is supplied in tape-and-reel packaging for automated assembly.
