• DIY electronics projects

Use in Power Supply Circuits:

• Connect the capacitor across the DC supply rail where bulk filtering is required.

• Observe correct polarity when installing.

• The positive terminal connects to the positive DC rail and the negative terminal connects to the negative or ground rail.

• In rectifier circuits, the capacitor can be used after the bridge rectifier to smooth pulsating DC.

• In switching power supplies and converters, it can provide bulk capacitance on suitable DC rails.

• Ensure the circuit voltage remains below the capacitor's 100V rated voltage.

• Consider ripple current and ESR requirements when selecting capacitors for high-frequency or high-power applications.

Use in Inverter and Charger Circuits:

• The 470µF 100V capacitor can be used as bulk DC-link capacitance in suitable low-voltage DC bus sections.

• It can help reduce voltage fluctuations caused by switching loads.

• Multiple capacitors can be connected in parallel when additional capacitance is required, provided voltage and ripple-current requirements are properly considered.

• For high-power inverter applications, select capacitors based on required ripple current, ESR, temperature rating and expected operating life rather than capacitance and voltage alone.

Installation Instructions:

• Switch off and completely isolate the circuit before installation.

• Discharge existing capacitors before replacing or installing components.

• Identify the positive and negative terminals.

• Install the capacitor with correct polarity.

• Do not exceed the 100V DC rated voltage.

• Ensure sufficient PCB clearance for the 35mm diameter and 40mm height.

• Verify lead spacing and mechanical clearance before PCB installation.

• After installation, inspect polarity and connections before applying power.

Important Safety Notes:

• This is a polarized electrolytic capacitor.

• Reverse polarity can cause excessive leakage current, heating, venting or capacitor failure.

• Never intentionally operate the capacitor above its rated voltage.

• Always discharge the capacitor before handling a circuit containing it.

• For high-voltage DC applications, allow an appropriate safety margin below the 100V rating.

• When used in high-ripple or high-frequency circuits, verify the capacitor's ripple-current and ESR specifications for the actual application.
