HCX5R

HCX5R is a designation used in electronic component catalogs to refer to a family of multilayer ceramic capacitors (MLCCs) that use X5R dielectric and are marketed as high-capacitance devices. The HC prefix is used by some manufacturers to denote a high-capacitance or general-purpose series.

Dielectric and performance: X5R is a ceramic dielectric class with moderate temperature characteristics, typically offering greater capacitance density than higher-stability types but with larger variation over temperature and voltage. In HCX5R parts, the series aims to combine relatively high capacitance values with compact form factors.

Construction and packaging: Available in standard surface-mount packages (chip sizes such as 0402 through 1210) and sometimes in radial formats; voltage ratings vary, commonly from a few volts up to 50V or more, depending on the size and manufacturer.

Applications and notes: HCX5R devices are used for decoupling, filtering, and energy storage in consumer electronics and power-management circuits where high capacitance in a small footprint is desired. Their temperature and voltage characteristics are less stable than X7R or C0G types.

Manufacturers and variability: Because HCX5R is not a universal industry standard, exact specifications differ by supplier. This can include differences in capacitance tolerance, ESR, inductance, and temperature coefficients. Always consult the specific datasheet for precise values.
