Description
This is a high-reliability, radial-leaded ceramic disc capacitor designed for critical safety applications in AC line filtering. Rated for X1 (250V AC) and Y1 (400V AC) safety classifications, this capacitor is engineered to fail safely, preventing electrical shock hazards and fire risks.
With a capacitance value of 470 picofarads (pF) and a generous 10mm (0.4 inch) lead pitch, it is ideal for use across the mains input in power supplies, converters, and industrial equipment. Its robust ceramic construction ensures excellent performance, high insulation resistance, and stability across a wide temperature range.
Key Features & Benefits:
- Dual Safety Certification: Meets stringent X1 and Y1 safety standards, making it perfect for bridging and bypassing AC supply lines.
- Reliable Failure Mode: Designed to fail open-circuit, ensuring user safety and protecting downstream components.
- High Voltage Rating: Suitable for direct connection to 250V AC line voltages.
- Wide Lead Pitch (10mm): Provides easy mounting on standard PCBs and maintains proper creepage and clearance distances for high-voltage applications.
- Excellent High-Frequency Response: Ideal for filtering electromagnetic interference (EMI) and radio frequency interference (RFI).
Typical Applications:
- EMI/RFI Filtering in Switch Mode Power Supplies (SMPS)
- AC Line Filtering (across line and line-to-ground)
- Industrial Power Controls
- Consumer Electronics Power Input Stages
- Lighting Ballasts
- Appliances and Power Tools
Typical Applications:
- Capacitance: 470pF
- Voltage Rating: AC 250V
- Safety Class: X1/Y1 250/400V Peak
- Dielectric Material: Class II (e.g., X7R, X7S) or Class I (NPO)
