Miniaturized X2-Film Caps from KEMET

X2-Film Caps for Harsh Environments

KEMET recently launched a new series of their X2 film capacitor portfolio for harsh environmental conditions, so-called THB-versions. With this R52 series, KEMET is first to market in terms of THB level, miniaturized dimensions and the highest capacitance value combined in one component.

Usually THB-version film caps have bigger dimensions compared to standard X2 caps due to their construction. KEMET has invested in a lot of research and long-term testing to improve this characteristic while retaining the other properties.

Miniaturized THB 500hrs 310VAC X2 Film Capacitors

R52 series is a miniaturized THB 500hrs 310VAC X2 film capacitor, which not only provides the same dimensions like the standard X2 310VAC version, but even smaller box sizes. Furthermore, KEMET reaches the small size of R46 275VAC “mini” series while retaining the same capacitance value. Thanks to this miniaturization, highest available capacitance is 22µF now.

The R52 series consists of metallized polypropylene film encapsulated with self-extinguishing resin in a box of material that meets the requirements of UL 94 V–0. It is ideal for harsh environmental conditions and meets the demanding AEC–Q200 qualification requirements.

For Electromagnetic Interference (EMI) Suppression

The series is intended for worldwide use in electromagnetic interference (EMI) suppression in across-the-line applications that require X2 safety classification, with special emphasis in automotive applications for severe ambient conditions. Typical applications as well include connection in series with the mains, capacitive power supplies and energy meters.
