Ripple Current and Power Load Capacitors are naturally limited by its capability to handle/dissipate ripple current and pulse energy load. The limitation may be significantly different by each capacitor technology but also within a specific product type individual series.
The maximum allowable ripple current is based on the capacitor’s power dissipation capability (as function of construction and case size) and expressed by maximum “self-heating” during the operation under ripple current load condition.
Continuous ripple current, power rating, transient/pulse capabilities etc. are the key parameters to consider for a proper capacitor selection in electric circuit design. Capacitors are naturally limited by its capability to handle/dissipate ripple current and pulse energy load.
Ripple Current and its Effects on the Performance of Capacitors The high immediate current spike is a typical short time ‘micro-seconds’ load zone during power switch ON/OFF of a high power, low impedance source circuit.
In longer time stamp, after all the transient events are over, the capacitor can be loaded up to its maximum specified continuous ripple current limit. The value is based on the capacitor’s ability to continuously dissipate the heat generated on its resistive elements.
Capacitors are naturally limited by its capability to handle/dissipate ripple current and pulse energy load. The limitation may be significantly different by each capacitor technology, dielectric type, its losses (and its characteristics), but also to a specific construction of the product type individual series.
