KEMET has announced the release of its M55 Module Polymer Hermetic Seal (PHS) capacitor portfolio.
KEMET's M550 and M551 Modular Series are designed for mission critical high capacitance and voltage applications and are manufactured by placing T550 or T551 Polymer Hermetic Seal capacitors in parallel. The M55 Series is suitable for telecom, computer, defence and aerospace applications.
With its robust anode quality, benign failure mode, mechanically robust assembly and epoxy housing, the M55 Series of modules are suitable for use in high voltage power management applications such as buck boost converters, filtering, hold-up capacitors, and other high ripple or high in-rush current applications. The M55 Modular Series provides extremely low and stable ESR and enhanced capacitance retention at higher frequencies and low temperatures, resulting in the highest total capacitance and most economical solution for high power applications.
KEMET has qualified the discrete components used in the M55 Series to DLA Drawing 13030 to ensure these products are suitable for high reliability applications KEMET, in association with entities within the space community and several KEMET aerospace customers, has confirmed that the rigorous testing options included in this comprehensive drawing are applicable to standard and high reliability flight applications including space. Discrete parts qualified according this drawing are available options for this modular capacitance solution.
The M551 Series offers all of the performance benefits of the M550 Series but with an increased temperature rating of 125˚C. The M550 modular series is rated at 105˚C.
