Thin Film Pulse Withstanding Chip Resistor /WF.S Series


Pulse Withstanding
Size: 0402 ~ 1206
TCR: 25ppm ~ 50ppm
Tolerance: 0.1% ~ 1%
Power rating: 1/16W ~ 1/4W


Anti-Surge thin film resistor with limited resistant range from 1ohm to 30 ohm, low TCR, and tight tolerance, the best choice for smart meter and measuring instrument, etc,.
The resistors are constructed in a high grade ceramic body, and use sputter technology for thin film resistant layer. For environmental soldering issue, the outer layer of these end terminations is a Lead-free solder.
