Ceramic Capacitors

This Product Selection Guide contains information to help select products in the Ceramic Capacitors category on DigiKey.com

A capacitor is a passive electronic device that stores electric charge. Ceramic capacitors consist of two or more alternating layers of ceramic material as the dielectric and metal layers acting as the non-polarized electrodes. Applications include automotive, bypass, decoupling, filtering, RF, and ESD protection. Through-hole versions are often disc or “blob” shaped with two wire leads.


SelectionCharacteristics

Capacitance: A measurement of the device’s ability to store an electrical charge. It is measured in Farads (F) and uses the metric system for values.

Tolerance: Characterizes the extent of permitted variability of overall device value among samples of a given part number, resulting from variations in manufacturing.

Voltage - Rated: Typically this represents the maximum voltage rating to which a device will meet its given specifications. Exceeding this voltage rating may damage the device and other system components.

Temperature Coefficient: Identifies the temperature range and the variance in capacitance over that range. For more information see Understanding Ceramic Capacitor Temp-Coefficients.

Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.

Features: These are different capabilities or properties of the device such as flame retardant, non-magnetic, or high voltage.

Ratings: Minimum performance standards of the device, which are typically set by a third party.

Applications: Identifies the type of equipment, environment, or function for which the device is intended for use.

Failure Rate: A factor used for reliability calculations that accounts for initial production quality, per MIL-HDBK-217. Typically N/A for parts not manufactured to military specification.

Mounting Type: Identifies how the device is attached.

Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the supplier’s device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.

Size / Dimension: The physical dimensions of the main body of the device. Typically listed as length x width.

Height - Seated (Max): Indicates how far the device will extend above the surface to which it has been attached.

Thickness (Max): Primarily applicable to surface-mounted devices; indicates maximum device dimension in a direction perpendicular to a device’s mounting plane.

Lead Spacing: Indicates the center-to-center spacing between adjacent leads.

Lead Style: Describes the geometry or shape of a device’s terminals. This primarily applies to products designed for through-hole mounting.
