33uf 25V 5*5.4 SMD Electrolytic Capacitor

Surface Mount Device (SMD) Aluminium Electrolytic Capacitors are passive components designed for Surface Mount Technology (SMT). They offer high capacitance in a compact size. These capacitors can be directly soldered onto Printed Circuit Boards (PCBs), making them ideal for high-performance electronic circuits with limited space.

Main Features:

1. Structure and Operating Principle:
   The electrical design of aluminium: A polarized component with anode (+) and cathode (-) terminals. SMD compatible: The flat base design allows for easy automated soldering using pick-and-place machines.
2. Advantages:
    
   • High capacitance: Wide range of capacitance (1µF to 1000µF and above).
   • Compact size: More space-efficient compared to traditional radial/through-hole capacitors.
   • Broad voltage range: Available in different voltage ratings (6.3 volts to 100 volts).
   • Handling high ripple currents: Suitable for pulsed current applications.
3. Technical Specifications:
    
   • Operating temperature: From -40°C to +105°C (varies by series).
   • Capacitance tolerance: Typically ±20%.
   • Lifespan: From 2000 to 5000 hours (depends on operating temperature and voltage).
   • Equivalent Series Resistance (ESR): Low to medium, with enhanced series for high-frequency applications.
4. Applications:
    
   • Power electronics: DC-DC converters, voltage regulators, SMPS (Switched-Mode Power Supplies).
   • Consumer electronics: LED drivers, TV and computer motherboards.
   • Industrial and automotive: Motor control units and industrial automation systems.
5. Packaging and Standards:
    
   • Sizes: Standard SMD footprints such as 5x5 mm, 6.3x7.7 mm, 8x10 mm (varies by manufacturer).
   • RoHS/REACH compliant: Environmentally friendly materials, compatible with lead-free soldering.
6. Main Considerations:
    
   • Polarity: Reverse connection may lead to explosion or leakage. (+) or cathode (cathode indicator) markings should be observed.
   • Thermal Management: High temperatures reduce product life; hence, proper ventilation and thermal design of the PCB are crucial.
   • Mechanical Stress: Excessive heat or physical pressure during soldering can damage the component.
