Cyntec has developed a series of current sensing resistor which characterized with miniaturization down to 0201 size, high power up to 9W, high precision, and low TCR. Besides the thin film and thick film, we develop the new processing technology to bond metal foil and ceramic substrate together. Base on the new technical perform, we can keep the competitive strength of low TCR. Otherwise, we also designed 4Pin-4Wire Kelvin's measurement on pad directly to decrease the measurement error.
