• Ripple Current Capability: Rated ripple current of 1.3 A at 120 Hz and 1.859 A at 50 kHz, enabling reliable handling of AC ripple in rectifier and converter applications.
• Temperature Range: Operating range from −25°C to +105°C to accommodate a wide span of industrial ambient conditions.
• Electrical Quality: Capacitance tolerance ±20% (at 120 Hz, 20°C) and leakage current specified as I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ max 0.15 for 200–400 V at 120 Hz, 20°C.
• Compact Footprint: Physical dimensions L: 4.5 × D: 2.5 cm for space‑constrained power designs.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).
• Polarized Design: Polar capacitor suitable for DC filter and smoothing applications.

Typical Applications

• Inverters: Bulk and filtering capacitor for rectifier and DC link stages in general inverter systems where high voltage and long life at elevated temperatures are required.
• Switching Power Supplies: Energy storage and smoothing for output and intermediate DC link circuits in industrial and commercial switching supplies.
• Rectifier Circuits: Smoothing and ripple reduction in AC‑to‑DC rectifier stages used in power conversion modules.
• Industrial Power Electronics: Support for high‑temperature, high‑stress environments common to industrial converters and power distribution equipment.

Unique Advantages

• Proven High‑Temperature Endurance: 5000 hours rated life at 105°C provides predictable aging characteristics for long service intervals.
• High Voltage Capability: 400 V rating enables use in higher‑voltage DC link and rectifier circuitry without multiple series parts.
• Effective Ripple Handling: Specified ripple currents at both 120 Hz and 50 kHz allow designers to size capacitors confidently for real‑world switching and rectification workloads.
• Compact Snap‑in Form Factor: Smaller‑sized radial can with snap‑in terminals reduces PCB area while providing robust mechanical retention.
• Measured Electrical Parameters: Clear leakage current and tan δ specifications (I ≤ 3√CV; tan δ ≤ 0.15 at 200–400 V) support accurate thermal and reliability modeling.
• Regulatory Compliance: RoHS compliance simplifies selection for applications requiring restricted‑substance conformance.
