MDL XPP Polypropylene 4.7mfd 250V。Buy Jantzen Capacitor 12uF 800VDC Superior Z-Cap Series Metalized。Get Auricap Capacitor 2.7uF 200Vdc XO Series Metalized Polypropylene。s-l1200.jpg。This is a Helix capacitor.I've decided to sell it as I won't be building a new audio system.I estimate it was used for about 3 months.I barely drove the car with the audio system installed.It comes with a holder, but screws are not included.Thank you for your consideration
