Key Features
- Genuine EPCOS Original: Fully traceable, factory-fresh units with authentic TDK-EPCOS markings and batch documentation.
- EMI Suppression Certified: Complies with IEC/EN 60384-14 Class X1/Y2 — suitable for across-the-line and line-to-ground noise filtering.
- High Surge Withstand: Robust design handles repetitive voltage surges up to 2.5 kV (impulse test per standard).
- Low Dissipation Factor: Typically tan δ ≤ 0.001 at 1 kHz and 20 °C for superior efficiency and minimal self-heating.
- Self-Healing Metallization: Automatically isolates localized dielectric faults — enhances reliability and longevity in industrial environments.
Typical Applications
The B32021A3104K is widely deployed in:
- EMI/RFI filters for motor drives, inverters, and power supplies
- Input stage filtering in industrial PLCs and control cabinets
- AC line interference suppression (X1-class across-phase, Y2-class line-to-ground)
- Renewable energy systems (e.g., solar inverters, wind turbine converters)
- Medical and laboratory equipment requiring certified safety capacitors
