While using an Electrolytic capacitor care should always be taken to connect the positive pin to the positive of the circuit and the negative pin to the negative of the circuit. Also the voltage appearing across the capacitor terminals should always be less than the rated capacitor voltage (V).
The Electrolytic Capacitors have polarity. Meaning they have a positive and negative pin. The pin which is long is the positive pin and the pin which is short is the negative pin. You can also identify the polarity using the negative strip on the capacitor label.
hing Circuits The Aluminum electrolytic capacitors for input smoothing circuits used on com cial voltages (100 VAC, 200 VAC) and commercial frequencies (60 Hz, 50 Hz) must have a high withstand voltage and a ripple current resistance complying with twice the commercial frequency (normally ful
Meaning they have a positive and negative pin. The pin which is long is the positive pin and the pin which is short is the negative pin. You can also identify the polarity using the negative strip on the capacitor label. As shown in the picture above the negative pin will be directly under the negative symbol.
nd a long life. Here we describe an example of an inverter application and the necessity of using an aluminum electrolytic capacitor in the inverter circuit a Use Inverter Electric motors are widely used in all types of matching equipment, building ventilator f
With non-solid electrolyte aluminum electrolytic capacitors the aluminum cases connect to the negative terminals by contact with electrolyte. The resulting isolation resistance may vary from a few ohms to a few thousand ohms. For axial leaded capacitors and flatpacks the case is connected to the negative lead.
