• Snap-in Mounting — Snap-in terminal, radial can package for secure PCB assembly and high-current board layouts.
• Ripple Current Capability — Low-frequency ripple current of 1.87 A at 120 Hz and high-frequency ripple current of 2.674 A at 50 kHz to handle dynamic power loads.
• Endurance — Rated life of 3000 hours at 85°C under rated ripple current conditions.
• Electrical Loss — tan δ (DF) = 0.15 measured at 20°C, 120 Hz, supporting predictable dissipation characteristics.
• Leakage Current — Specified leakage current: 1010 µA (as provided in product data).
• Temperature Range — Operates from −25°C to +85°C per product specifications for 350 V and above ratings.
• Tolerance & Polarity — Capacitance tolerance of −20% to +20%; polarized electrolytic construction.
• Compliance & Packaging — RoHS compliant and available in tray packing; product is listed as mass production.

Typical Applications

• General-Purpose Power Filtering — Bulk smoothing and ripple suppression in general-purpose electronic power circuits where 350 V withstand and 330 µF capacitance are required.
• High-Ripple Current Power Assemblies — Snap-in mounting and specified ripple current ratings support use in power modules and assemblies with sustained ripple loading.
• PCB Mounted Power Components — Radial, snap-in can design for straightforward integration into board-level power designs that require robust mechanical retention.

Unique Advantages

• 350 V Rated Voltage: Supports higher-voltage DC applications without additional series stacking.
• Proven Endurance: 3000 hours at 85°C under rated ripple current provides a clear endurance specification for lifetime planning.
• Dual-Frequency Ripple Performance: Specified ripple current at both 120 Hz and 50 kHz enables predictable behavior across low- and high-frequency power environments.
• Compact Snap-in Form Factor: φ22 × 45 mm radial can with snap-in terminals delivers a compact, board-secure solution for high-voltage bulk capacitance.
• Low Loss Characteristic: tan δ = 0.15 at 20°C, 120 Hz helps quantify dissipation for thermal and reliability assessments.
• Regulatory Compliance: RoHS compliant to support regulatory requirements.
