MPH series

     IC Type MPH series capacitors are designed to operate at the specified rated maximum DC Working Voltage over a temperature range of -55°C to +105°C.Operation at temperatures up to and including +105°C are permissible without derating.So MPH series are suitable for high frequency and high current applications.
      MPH series have four features.The first one is about high ripple current ratings.The second one is about low ESR.The third one is about stable capacitance versus frequency and temperature.
      The following is about specification of MPH series.Capacitance tolerance would be within ±10%(K) at 1000Hz and 20.Operating temperature range should be -55 to +105.The voltage range of MPH series is from 100 WVDC to 400 WVDC.Dissipation factor is less than 0.1% at 1kHz.Insulation resistance is more than or equal to 200,000 M x F,not to exceed 400,000M.Load life should be 1,000 hours at +85°C with 125% Rated WVDC when capacitance change±3%of initial readings at +25°C @ 1kHz,dissipation factor 0.1% of initial reading at 1kHz @ +25°C and insulation resistance 50% of minimum initial limit @ +25°C.Self-inductance is less than or equal to 1nH/mm along the capacitor body and leads.Capacitance drift factor would be within ±1.0% (after 2 years).Maximum Pulse Rise Time is 10 v/ sec.
      The following is a construction of MPH series.Type is extended metallized film.Dielectric is polypropylene film.Electrodes are vacuum deposited aluminum layers.Leads are Tinned copper wire(MPH or tinned copper lugs (MPL).Coating is made of Flame retardant polyester tape wrap (UL510) with epoxy end seals UL94V-0.
