TT Electronics Welwyn 100K SMD Chip Resistor 0805 0.1W
Precision 100K thin film SMD chip resistor by TT Electronics. 0805 case, ±0.1% tolerance, 100mW, 100V rating. Ideal for PCB assembly.
The TT Electronics / Welwyn PCF Series Precision Thin Film Chip Resistor offers high reliability and stability for demanding electronic applications. Featuring a precision thin-film nichrome element selectively deposited on a 96% alumina substrate, this resistor ensures consistent performance. The unadjusted resistors undergo a heat treatment process to achieve the required temperature coefficient of resistance (TCR) and stability, followed by a precisely controlled laser trim process to adjust the resistance value to exact specifications.
Construction and Protection
Epoxy protection is applied to the element, and wrap-around terminations are added, plated with Nickel and then Tin. The standard termination is 100% Sn matte plated wrap-around, which is highly suitable for soldering. A passivated range provides superior humidity performance, ensuring durability in challenging environments.
Assembly and Integration
Ideally suited for handling by automatic methods, the PCF resistor features a rectangular shape and small dimensional tolerances. Electrical connections to a ceramic substrate or printed circuit board can be made by reflow or wave soldering of the wrap-around terminations.
