Evox-Rifa PHE 426 MKP 250VDC – 5% tolerance

Evox-Rifa PHE 426 MKP 250VDC – 5% tolerance

Technical Specifications: “Single metallized polypropylene film pulse capacitor. Pulse operation in SMPS, TV, monitor, electrical ballast and other high frequency applications demanding stable operation. Polypropylene film capacitor with vacuum evaporated aluminium electrodes. Radial leads of tinned wire are electrically welded to the contact metal layer on the ends of the capacitor winding. Encapsulation in self-extinguishing material meeting the requirements of UL 94V-0. Two different winding constructions are used, depending on voltage and lead spacing”.

Sound: Similar to the Evox-Rifa PHE 450, the PHE 426 is transparent and clear sounding but less grainy. The treble still has a slight “glaze” over it, but it 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. Similar in character to the Obbligato aluminium dry type, only it misses the “analogue” feeling to it. Compared to a Mundorf RXF it is a little brighter. 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+
