The CH0402-50RGF is a 50R 50mW SMD Chip Resistor with SnAg over nickel barrier termination. The high frequency thin film chip resistor is made with thin film microwave and pure alumina substrate (99.5%). These miniaturized components are designed in such a way that its internal reactance is very small. When correctly mounted and utilized, it functions as almost pure resistor on a very large range of frequency up to 50GHz.
