Y4485V0640BQ9W

Y4485V0640BQ9W Description

The Y4485V0640BQ9W is a high-precision 2-resistor voltage divider network from VPG Foil Resistors' DSMZ series, designed for applications requiring ultra-stable TCR-matched performance. With a 250Ω/250Ω resistance ratio, this surface-mount device delivers exceptional accuracy (±0.1% tolerance) and minimal drift (±0.2ppm/°C TCR, ±0.02% resistor matching ratio). Its compact 4.06mm x 2.69mm footprint and low profile (1.80mm height) make it ideal for space-constrained PCB designs. The 50mW power rating per element and ±0.1ppm/°C resistor-ratio drift ensure reliability in demanding environments.
