SMD Capacitor Code Calculator

Marking systems are compact identifiers. Dielectric, voltage rating, package and DC-bias behavior are separate component properties.

Capacitor marking

Format

—Numeric codes are interpreted in picofarads.

—Picofarads

—Encoded tolerance

Capacitance is only one component property

A compact marking can encode nominal capacitance and sometimes tolerance. Voltage rating, dielectric, ESR and DC-bias behavior are separate.

The value character may be uppercase or lowercase. Preserve the printed case before decoding.
