Type selection analysis of the capacitor

 

★ For products in the same product series and capacitance with different dimension, the bigger the dimension is, the higher the working voltage will be and the frequency range will be lower.

Product Dimension Capacitance Working Voltage First parallel resonant frequency

DLC75D100 0805 10pF 250VDC 5.2GHz

DLC75B100 1210 10pF 500/1000VDC 4.2GHz

 

★ For products in the same product series and dimension with different capacitances, the bigger the capacitance is, the lower the working voltage will be and the frequency range will be lower.

Product Dimension Capacitance Working Voltage First parallel resonant frequency
