Y1485V0011BA9R

Y1485V0011BA9R Description

The Y1485V0011BA9R from VPG Foil Resistors is a high-precision 2-resistor voltage divider network designed for applications requiring ultra-stable TCR-matched performance. Part of the DSM series, it features a compact surface-mount footprint (4.06mm x 2.69mm) with a low profile (1.80mm max height), making it ideal for space-constrained PCB designs. The network combines 1kΩ and 4kΩ resistors with an exceptional ±0.1% tolerance and ±2ppm/°C temperature coefficient, ensuring minimal drift (±0.5ppm/°C ratio drift) over temperature variations. Its ±0.05% resistor matching ratio and 50mW power rating per element deliver unmatched accuracy in signal conditioning and reference circuits.

Y1485V0011BA9R Features

• Precision TCR Matching: ±2ppm/°C TCR ensures stability in temperature-sensitive environments.
• Ultra-Tight Tolerance: ±0.1% resistance tolerance and ±0.05% ratio matching for critical applications.
• Low Drift: ±0.5ppm/°C resistor-ratio drift guarantees long-term reliability.
• Compact & Robust: Surface-mountable in a 3-pin strip package (MSL1, RoHS3 compliant).
• High Power Handling: 50mW per resistor for demanding circuits.
• Wide Compatibility: EAR99/HSUS8533.21.0020 classified for global deployment.
