- Protective Housing: Metal or high-strength plastic casing offering IP44 protection.
- Identification Label: Printed with key parameters (model number, rated voltage, capacitance) for easy on-site identification and maintenance.
Typical Applications
- Power Factor Correction (PFC) circuits in distribution cabinets, frequency converters, and inverters.
- Power supply filtering and suppression in industrial automation control systems.
- Power systems requiring high reliability, such as rail transit, railway signaling, and avionics.
- Input filtering for renewable energy (solar PV, wind power) inverters.
- Any applications needing to improve power grid quality and reduce harmonics.
Installation & Maintenance Guidelines
- Pre-installation Check: Ensure PCB pads are clean and free of oxidation to guarantee soldering quality.
- Soldering Method: Reflow soldering or wave soldering is recommended. Control soldering temperature between 220 °C – 250 °C and duration within 30 seconds to prevent component overheating.
- Protective Measures: In humid or dusty environments, ensure the housing is intact to prevent moisture infiltration.
- Regular Inspection: Conduct visual inspections every 12 months to check for loose solder joints and damaged housings.
- Replacement Principle: Immediately replace the component if capacitance deviates by more than ±10%, leakage current is abnormal, or the housing is cracked.
- Storage Requirements: Store in a dry environment with temperature ranging from 15 °C – 25 °C, avoiding electrostatic discharge (ESD) damage.
