Power Ring Film CapacitorsTM
SBE Part 700D158911-590
Thermal Specifications
Here are two representations of “Capacitor Surface
Temperature over Time” for two specific Thermal
Resistances of 1°C/W and 0.5°C/W.
Notes regarding these graphs:
• The thermal resistance is that from capacitor to
application.This is a function of the application
environment, not the capacitor itself.
• The capacitor can handle extreme current for small
duty ratios.Trise occurs very slowly.This is because
the capacitor has a high specific heat.
• These charts can be adapted for other currents by
multiplying y axis values for any time by (Iapp/254)²
• Internal capacitor Trise is added to the capacitor
surface/terminal temperature.
• Terminals are assumed to be at case temperature.
