CHIP TYPE FEED THROUGH CAPACITORS [ CTH Series ]
The CTH Series is made of ceramics on which low-resistance multilayer electrodes are formed. The simple structure and high
withstanding voltage are suitable for high-frequency noise control in large-current circuits.

ENERAL CATALOG
• The structure will hardly allow residual inductance, and the self resonant frequency extends to the microwave band. Ideal for
high-frequency noise control.
• The multilayer electrode structure excels in solder heat resistance and solderability. It is also applicable to Pb-free solder.
• RoHS Compliant.
