High pass filter of high-frequency circuit usually adopts ceramic capacitor. in the practical designing, the selection of capacitance is very important, the function is different according to the different frequency. so the high pass filter should be designed according to eleminating high freguency noise and reduceing the unneccesary radiation quantity. The high pass filter can get excellent performance by using the Three terminals capacitor . The structure and equivalent circuit of Three terminals capacitors is showed as the below chart. The electrode of the capacitor connects the U lead, and the anode of the capacitor is the input and output end. When working, the U lead connects the mainsside and the terminals for power supplies of the opposite lead near the electronic device connects human. If the connection is good, the attenuation performance can improve to 10dB.
