AUDYN CAP MKP QS 400 VOLT & 630 VOLT RANGES A fast, audiophile MKP capacitor, featuring a lively reproduction of ... read moremusic. The MKP QS series of capacitors are highly recommended for use in quality loudspeaker crossovers, series connected to high-frequency drivers as well as mid-range drivers. MKP QS capacitors are also highly recommended for use in valve amplifiers. Two voltage ratings are available, 400 Vdc/250 Vac and 630 Vdc/400Vac. These capacitors offer a low loss-factor (Loss Angle Tan: 0.0003 at 1 kHz/20oC) as well as very good temperature related performance. Specifications: Loss Angle Tan: 0.0003 (1 kHz; 20oC) Tolerance: +/-5% Connecting leads: Axial, tinned copper, 35mm long. Operating temperature: -25oC - +85oC Diagram/Chart headings for both 400Vdc and 630Vdc charts MKPQS Part No./Value uf/Length/diameter/d2=diameter of connecting lead/Type Graph at bottom left of page shows capacitance accuracy (or deviation) at ambient temperatures between -40oC up to +90oC for both MKP and MKT capacitors. The graph on the bottom right of the page shows capacitance accuracy (or deviation) at ambient temperatures between -40oC up to +90oC for MKP and KPSN capacitors.
