Ceramic capacitors knowledge to bring you different capacitors

There are various types of ceramic capacitors. As shown in Table 1, it is a major feature of Murata to develop and supply products for various purposes according to customer needs.

General purpose capacitors for general electronic equipment

Standard ceramic capacitors. The product lineup is rich, ranging from 0.4×0.2mm to 5.7×5.0mm, the capacity is from 0.1pF to 100uF, and the various products with rated voltages from 4Vdc to 630Vdc are available. The amount used in ceramic capacitors is also the largest.

High frequency low loss capacitor

A product developed for high-frequency circuits such as mobile phones, communication modules, and mobile communication base stations. High frequency and low loss are achieved by using Cu having a small resistivity at the internal electrodes.

Miniature chip capacitor

A product developed for high-speed wireless communication circuits or ICs such as ICs in optical communication equipment. Since Au is used in the surface electrode, high frequency characteristics are good and adhesion is excellent.

Low ESL capacitor

A product developed to reduce the ESL value and achieve high-speed charge and discharge by a high-frequency circuit such as a CPU. Low ESL is achieved by shortening the current path or by configuring the electrodes to counteract the electromagnetic field.

Discharge capacitor

A product developed to increase component packing density and reduce assembly costs. The world's smallest specification - a 0.3 × 0.2mm size capacitor is available.

Medium and high voltage capacitor

The capacitor uses a ceramic dielectric with a high dielectric breakdown voltage and improves the internal electrode structure to achieve a rated voltage of kV units. In addition, Murata also has a primary side X capacitor and a Y capacitor that are certified by international safety standards.

Trimmer capacitor

A product developed to continuously change the capacitance value of a capacitor. Fine-tune the oscillation circuit frequency and the impedance matching of the circuit.
