Tantalum Through-Hole Capacitors – Hermetically Sealed
M55 Module Polymer Hermetic Seal
Overview
KEMET's M550 and M551 Modular Series are manufactured
by placing T550 or T551 Polymer Hermetic Sealed
Capacitors (PHS) in parallel or series. The T550 and T551
Series are made utilizing 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 8,200 µF), extremely low
ESR (down to 15 mΩ) and extremely low and stable leakage
current, all in a mechanically robust package.
The M55 Modules are available in two temperature offerings:
105°C (M550 Series) and 125°C (M551 Series). With
reduced ESR and enhanced capacitance retention at higher
frequencies and low temperatures, KEMET modules provide
the highest total capacitance and the lowest total cost of
ownership for high power applications.
Benefits
Applications
• Extremely low and stable ESR (as low as 15 mΩ)
• Voltage Ratings from 6 to 180 VDC
• High frequency capacitance retention
• Low temperature capacitance stability
• High ripple current capability (17,500 mArms)
• High inrush current capability
• Excellent power dissipation capability
• Stackable packaging
• Mechanically robust assembly and epoxy housing
• Operates at up to 80% rated voltage
• Customized solutions available
• RoHS compliant terminations available
Designed for mission critical applications requiring high
power, filtering, hold-up, and current pulse generation.

Ripple Current/Ripple Voltage
Permissible AC ripple voltage and current are related to equivalent series resistance (ESR) and the power dissipation
capabilities of the device. Permissible AC ripple voltage that may be applied is limited by two criteria:
1. The positive peak AC voltage plus the DC bias voltage, if any, must not exceed the DC voltage rating of the capacitor.
2. The negative peak AC voltage in combination with bias voltage, if any, must not exceed the allowable limits specified
for reverse voltage.
The maximum power dissipation by case size can be determined using the below left table. The maximum power dissipation
rating stated in the table must be reduced with increasing environmental operating temperatures. Refer to the below right
table for temperature compensation requirements.

Using the Pmax of the device, the maximum allowable rms
ripple current or voltage may be determined.
I(max) = √Pmax /R
E(max) = Z √Pmax /R
I = rms ripple current (amperes)
E = rms ripple voltage (volts)
Pmax = maximum power dissipation (watts)
R = ESR at specified frequency (ohms)
Z = Impedance at specified frequency (ohms)
The maximum power dissipation rating must be reduced with increasing
environmental operating temperatures. Refer to the Temperature
Compensation Multiplier table for details.

Reverse Voltage
Solid tantalum polymer capacitors are polar devices and may
be permanently damaged or destroyed if connected with
the wrong polarity. A small reverse voltage is permissible
for time periods per the table at right. KEMET can offer
lower capacitance in this voltage with higher reverse voltage
capability. In addition, we continue to improve our capability
for this characteristic.

Mounting
The M550 and M551 Modular Series are suitable for stacking to the board. The use of a heat sink is recommended.
These products are not suitable for reflow soldering. For manual-soldering process with soldering iron, the maximum
recommended temperature is 350°C for no more than 3 seconds. Care should be taken to avoid contact of the soldering iron
to the epoxy housing. The iron should be used to heat the solder pad, applying solder between the pad and the terminal of
the module, until reflow occurs.

Storage
Polymer Hermetic Seal Modules should be stored in normal working environments. KEMET recommends that maximum
storage temperature not exceed 40°C and maximum storage humidity not exceed 90% RH. For optimal solderability, module
stock should be used promptly, preferably within three years of receipt.
Packaging
Modules shall be packaged in carton boxes. Packaging
methods and materials used shall prevent degradation of
physical and mechanical characteristics. MSL 1
