Dear @jasbirnandra : This is the Vishay alternative to Wima and Kemet: chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/viewer.html?pdfurl=https%3A%2F%2Fwww.vishay.com%2Fdocs%2F28173%2Fmkp383.pdf&clen=164592&chunk=true R. |
Some general recommendations: - Do NOT change the capacitance value of your capacitor. The design calculations are based on its existing value. - DO change it as long as you are INCREASING its voltage rating. Never any harm in increasing its voltage rating. - Do NOT *EVER* replace a bi-polar capacitor with a polar one, otherwise it may blow up. |
You can change the value of an output coupling cap and do so safely and do so to better effect. But, as a general principal you want to stay near tolerances as designed. Sometimes people violate rule no 2 above because they want to better match impedance between amp and preamp. Manufacturers usually try to pick a level that will match with a larger number of combinations yet you can customize this so the gear mates better. There are good calculators out there for this purpose. |
Here’s a great calculator to use when matching output caps. http://www.v-cap.com/coupling-capacitor-calculator.php |
