TT ELECTRONICS / WELWYN 10.2kΩ Thin Film Chip Resistor, ±0.1%, 0.1W, 0805

The TT ELECTRONICS / WELWYN PCF Series precision thin film chip resistor is an exceptionally accurate and stable 10.2kΩ (10K2) component, designed for demanding electronic applications. Featuring a low tolerance of ± 0.1% and a 0.1W (100mW) power rating, it ensures reliable performance in precision circuits where consistency is critical.

Constructed with advanced thin-film nichrome technology, the resistor element is selectively deposited onto a high-purity 96% alumina substrate. The manufacturing process includes heat treatment for optimal Temperature Coefficient of Resistance (TCR) and stability, followed by a precisely controlled laser trim to achieve the exact resistance value. A protective epoxy coating is applied, and the wrap-around terminations are plated with Nickel and a 100% Tin (Sn) matte finish for excellent solderability.

This 0805 2012 Metric sized component is part of the passivated range, offering superior performance in humid environments. Its rectangular shape and tight dimensional tolerances make it ideally suited for high-speed automatic placement equipment. Electrical connection to ceramic substrates or printed circuit boards (PCBs) can be easily achieved using standard reflow or wave soldering techniques.
