Y1485V0004AT9W

Y1485V0004AT9W Description

The Y1485V0004AT9W from VPG Foil Resistors is a high-precision, surface-mount resistor network designed for demanding voltage divider applications. Part of the DSM series, this device integrates two 1kΩ resistors with an ultra-tight tolerance of ±0.05% and a near-perfect resistor matching ratio of ±0.01%. Its compact 1610 package (4.06mm x 2.69mm) and low-profile design (1.80mm max height) make it ideal for space-constrained PCB layouts. The network excels in environments requiring minimal thermal drift, featuring a ±2ppm/°C temperature coefficient and a resistor-ratio drift of just ±0.5ppm/°C.
