AX : Polypropylene Capacitor: 250Vac & 400Vdc rated
Polypropylene axial wrap and end seal style capacitors offering low loss characteristics. Ideally suited to applications such as mains filters and where pulse performance is important.
Product description
AX capacitors are constructed using the familiar wrap and end seal method - wrapping the wound elements with heavy duty electrical tape which is wider than the element and sealing the cavities formed at each end with epoxy resin. This style of manufacture results in a cost effective and volumetrically efficient component of the highest quality.
Designed to meet the requirements of EN132400 for Class X2 Capacitors at 250Vac (mains) applications.
The capacitors are also suitable for pulse type circuits where high peak current handling capability is essential or at high frequency ac voltages where low loss is of prime consideration.
If you have a specific requirement or query then please contact us, alternate capacitances, aspect ratios, lead outs are possible to meet specific requirements.
