Datasheet

Now available in Europe through TTI is KEMET’s M55 modular PHS (Polymer Hermetic Sealed) capacitor series designed for defense and aerospace applications requiring high power, filtering, hold-up and current pulse generation. KEMET's M550 and M551 modular series components are being manufactured by placing T550 or T551 PHS capacitors in parallel.

T550 and T551 series devices utilise KEMET’s exclusive F-Tech process and are 100% tested per KEMET’s patented Simulated Breakdown Screening process.

This configuration provides high and stable capacitance (up to 8,200μF), extremely low ESR (down to 15mΩ) and extremely low and stable leakage current, all in a mechanically robust package.

The M55 series modules are available in two temperature offerings: 105°C (M550 Series) and 125°C (M551 Series) and operate at up to 80% rated voltage. With reduced ESR and enhanced capacitance retention at higher frequencies and low temperatures, the modules provide the highest total capacitance and the lowest total cost of ownership for high power applications.

Further technical details of M550 and M551 modular series components include a high ripple current capability (17,500 mArms), high in rush current capability, excellent power dissipation capability, and a stackable packaging. Customised solutions as well as RoHS compliant terminations are available upon request.
