Evox-Rifa PHE 450 MKP 250VDC – 5% tolerance

Technical Specifications: Double metallized polypropylene film pulse capacitor intended for high frequency, high current stress applications. Typical Application: Protection circuit in SMPS and Electronic Ballasts. Encapsulated in self-extinguishing material meeting the requirements of UL94V-0. Only available in values up to 4,7mF.

Sound: The Evox-Rifa PHE 450 is a very transparent and clear sounding capacitor, some times a little too “fresh” sounding but this character can be compensated by adding a capacitor with a more round character – I had very good results with about 10% of the total value made up from Angela (Jensen) paper in oil. On its own I find the midrange a little under exposed and the treble has a slight “glaze” over it, which again can be removed by bypassing it with a Vishay MKP1837. Imaging is quite good with a nice sized sound stage but only average separation. Dynamics are nice and snappy and the treble is well detailed. It might seem that I am not too keen on the PHE 450 but this is just a way of trying to describe its character in words – I still find it a very nice little capacitor considering the price. This capacitor has a high price/quality ratio and matching it with other capacitors to create a custom capacitor gives very good results.

Verdict: 7
