MKP 1839 HQ  
AC and Pulse Metallized Polypropylene Film Capacitors  
MKP Axial Type  
Vishay Roederstein  
POWER DISSIPATION AND MAXIMUM COMPONENT TEMPERATURE RISE  
The power dissipation must be limited in order not to exceed the maximum allowed component temperature rise as a function of  
the free air ambient temperature.  
The power dissipation can be calculated according type detail specification “HQN-384-01/101: Technical Information Film  
Capacitors with the typical tgd of the curves”.  
The component temperature rise (ΔT) can be measured (see section “Measuring the component temperature” for more details)  
or calculated by ΔT = P/G:  
• ΔT = Component temperature rise (°C)  
• P = Power dissipation of the component (mW)  
• G = Heat conductivity of the component (mW/°C)  
MEASURING THE COMPONENT TEMPERATURE  
A thermocouple must be attached to the capacitor body as in:  
Thermocouple  
The temperature is measured in unloaded (Tamb) and maximum loaded condition (TC).  
The temperature rise is given by ΔT = TC - Tamb  
.
To avoid radiation or convection, the capacitor should be tested in a wind-free.  
APPLICATION NOTE AND LIMITING CONDITIONS  
These capacitors are not suitable for mains applications as across-the-line capacitors without additional protection, as described  
hereunder. These mains applications are strictly regulated in safety standards and therefore electromagnetic interference  
suppression capacitors conforming the standards must be used.  
To select the capacitor for a certain application, the following conditions must be checked:  
1. The peak voltage (UP) shall not be greater than the rated DC voltage (URDC  
)
2. The peak-to-peak voltage (UP-P) shall not be greater than the maximum (UP-P) to avoid the ionisation inception level  
3. The voltage pulse slope (dU/dt) shall not exceed the rated voltage pulse slope in an RC-circuit at rated voltage and without  
ringing. If the pulse voltage is lower than the rated DC voltage, the rated voltage pulse slope may be multiplied by URDC and  
divided by the applied voltage.  
For all other pulses following equation must be fulfilled:

T is the pulse duration.  
4. The maximum component surface temperature rise must be lower than the limits (see figure max. allowed component  
temperature rise).  
5. Since in circuits used at voltages over 280 V peak-to-peak the risk for an intrinsically active flammability after a capacitor  
breakdown (short circuit) increases, it is recommended that the power to the component is limited to 100 times the values  
mentioned in the table “Heat conductivity”.  
6. When using these capacitors as across-the-line capacitor in the input filter for mains applications or as series connected with  
an impedance to the mains the applicant must guarantee that the following conditions are fulfilled in any case (spikes and  
surge voltages from the mains included).
