CH0402-100RJF
Thin Film Surface Mnt Resistor 0402 Case 100Ω +/-5% 0.05W1/20W +/-100ppm/degC
Those miniaturized components are designed in such a way that their internal reactance is very small. When correctly mounted and utilized, they function as almost pure resistors on a very large range of frequency, up to 20 GHz.
