Cross-reference table

The CV series matches the Eurofarad (now Exxelia) HT series model-for-model: rated voltage, capacitance range, dimensions and axial leaded design are identical — replacement requires no PCB redesign or mounting changes.

Scope note (CV series takes precedence): the axial mica capacitor series of the organic–mica–ceramic catalog (CY, CY2/CY2C, CY8, CY9, CY10, C76, C78, C79, C86, CV8, CV81C/CV71, C12, GK41, etc.) are now supplied exclusively under the CV series. Where models overlap with the CV series, CV series specifications prevail (operating temperature −55 °C to +155 °C, up to +250 °C on special order). The CY5 chip mica capacitor (SMD) remains a separate model due to its different package form.
