Features
High Frequency High Q Type 1005(in mm)/0402(in inch) Size Max.
GJM Series
This product improves the high frequency characteristics and contributes to a
reduction of power consumption by the High Q and low ESR.
Mainly ideal for mobile communication devices and temperature compensation of related modules.
1
High Q and low ESR in VHF, UHF and microwave frequency bands.
2
This product is ideal for temperature compensation of high frequency circuits, such as resonant circuits,
tuning circuits, and impedance matching circuits where the operating characteristics of the device are greatly
affected by the capacitance fluctuation.
High Q and low ESR were achieved at a high frequency by adopting ceramic material as the dielectric material
which enables an extremely low loss at high frequency, and base metal electrodes as the internal electrodes.
