Introduction to Capacitors, Capacitance and Charge
Practical capacitors are available commercially in many different forms. The type of internal dielectric, the structure of the plates and the device packaging all strongly affect the characteristics of the capacitor, and its applications. Values available range from very low (picofarad range; while arbitrarily low values are in principle possible, stray (parasitic) capacitance in any circuit is th…
When the lead spacing of a capacitor does not match the hole spacing on your PCB, the capacitor should have its leads formed to avoid exposing the capacitor to excessive mechanical stress. As Figure 1, if the angle of the leads is greater than 30°, lead forming will be required. Figure 1: If you need to reform the leads, please refer to the …
