Ceramic Capacitors

Ceramic capacitors are fixed-value capacitors where ceramic materials act as dielectrics. When an electrical circuit is connected to a voltage source, the ceramic capacitor stores an electrical charge in an electrostatic field between its conductors. Inside every EMI filter is a ceramic feedthrough capacitor. EMI suppression ceramic capacitors eliminate RF noise generated by electronic devices by reducing the input impedance. These components provide very accurate results, and the capacitance values of these capacitors are stable concerning the temperature, applied voltage, and frequency.

The two most frequently used types of ceramic capacitors are multi-layer ceramic capacitors, generally the capacitor of choice for applications where small-value capacitances are needed, and ceramic disc capacitors, often used as safety capacitors in electromagnetic interference suppression applications such as discrete EMI filters, filtered d-sub connectors, and filtered circular connectors.

	Tubular Capacitors: Small, lightweight, high dielectric strength, and are impervious to moisture and contamination.
	Discoidal Capacitors: Low profile and rugged design offering an excellent alternative to ceramic tube designs.
	Planar Array Capacitors: Low profile and capable of meeting various geometric and electrical configurations.
	Switchmode Power Supply Capacitors: Multi-layer assemblies with low ESR/ESL and are ideal for DC-DC applications
NEW Product!	High Voltage Chip Capacitors: Surface mount chip capacitor for applications with high voltage requirements up to 2500VDC.
