Either should work, at room temperature. The polypropylene ones will probably handle a warmer ambient a bit better. And cost more and be larger. Pick a unit that has a DC voltage rating about twice the peak voltage the PWM applies, to compensate for the high AC content of the voltage and internal temperature rise from ripple current.

Hi all,
Im after a bit of advise regarding the different types capacitors,
I need to "trick" a PWM circuit that monitors feedback from the solenoid = it controls, in order to give the solenid less current. [long story for = its purpose, the PWM circuit cannot be modified because it has been = potted)
My intentions are to use a resistor and capacitor in parallel with the = solenoid, and a resistor in series with the solenoid. (I have it = currently working the way I want it.) The unit that controls the solenoid will go into a fault mode if the = parallel resistance is too little (
