UPCA – Ultra-Precision Chip Array

The UPCA164 is an ultra-precision chip array which incorporates four resistor elements in a compact 1206 footprint. This is a nichrome film precision part, like the existing PCA but with a threefold improvement in temperature stability.

UPCA and PCA arrays with convex terminations are the thin film equivalent of the thick film array BCN164AB, and are for use in applications which demand higher levels of precision.

As an integrated component, UPCA offers several advantages over discrete precision chip resistors of the same absolute precision, including matching tolerance to ±0.05% and tracking TCR to ±5ppm/°C.
