TT Electronics SMD Chip Resistor 56.2kΩ 0.1% 0603

The TT Electronics / Welwyn PCF Series Precision Thin Film Chip Resistor offers exceptional accuracy and stability for demanding electronic circuits. Constructed using a nichrome thin-film selectively deposited onto a 96% alumina substrate with metallic contacts, this resistor undergoes a rigorous heat treatment process to achieve the required temperature coefficient of resistance (TCR) and long-term stability. A precisely controlled laser trim process then adjusts the resistance value to ensure exact specifications are met.

Featuring epoxy protection and wrap-around terminations plated with nickel and tin, the PCF resistor is designed for reliability. It includes a passivated range for superior humidity performance and standard 100% Sn matte plated wrap-around terminations, making it highly suitable for soldering applications.

Handling and Installation

Thanks to its rectangular shape and small dimensional tolerances, this SMD chip resistor is ideally suited for handling by automatic placement methods. Electrical connections to a ceramic substrate or printed circuit board can be easily made using reflow or wave soldering techniques.
