WhatsAppThe above image shows a Mylar film capacitor. The top "683" marking indicates the capacitance value, which is 68,000 picofarads (pF). To get this value, you multiply the leading digits (68 in this case) by 10 raised to the power of the last digit (3), and the result is the capacitance in picofarads (in this case, we get 68×10 3 pF). There are …

WhatsAppAs we know the definition of Loss Tangent in capacitor which it is: When a sinusoidal alternating voltage is applied to an ideal capacitor, the current advances by pi/2 in phase. In the case of a practical capacitor, however, advance in phase is (pi/2 - delta), which is smaller than pi/2. "delta" is referred to as Loss Angle.
WhatsAppI am building a power supply circuit, and the switching regulator calls for a low-ESR output capacitor.The capacitor in question is C3 of the evaluation board circuit. What does "low" mean? How low? Also, how do I find or calculate the ESR for a capacitor whose datasheet does not have a parameter called ESR?
WhatsAppAt a frequency of 60 Hz, the 160 millihenrys of inductance give us 60.319 Ω of inductive reactance.
