Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance, providing high-voltage bulk energy storage for power conversion circuits.
• Snap-in Radial Can Package — Snap-in terminal mounting in a compact 22 × 25 mm can (D × L) simplifies PCB insertion and secure mechanical retention for power assemblies.
• High Ripple Handling — Rated ripple current of 1.1 A at 120 Hz and 1.65 A at 50 kHz supports continuous AC ripple conditions typical in rectifier and switching environments.
• Long-Life Endurance — Endurance specified to 5000 hours at 105°C under DC bias plus rated ripple current, with defined limits for capacitance change, dissipation factor, and leakage current after test.
• Operating Temperature Range — Specified for use from −25°C to +105°C to match elevated-temperature power electronics applications.
• Leakage Current — Initial leakage current characteristic provided (0.77 mA for the 330 µF, 22 × 25 mm variant), with limits maintained after endurance testing per the datasheet.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Inverter Rectifier Circuits — Bulk smoothing and ripple reduction for rectifier stages in general inverter designs.
• Switching Power Supplies — Energy storage and output filtering to support stable DC rails and transient handling in switching supplies.
• General Purpose Power Filtering — Polarized bulk capacitance for a variety of power conversion and conditioning circuits requiring 200 V class capacitors.

Unique Advantages

• Designed for Long-Term High-Temperature Use — 5000-hour endurance at 105°C provides predictable performance retention in hot power assemblies.
• Compact, Secure Snap-In Packaging — 22 × 25 mm radial can with snap-in terminals enables compact board layouts and reliable mechanical mounting for power modules.
• Measurable Ripple Performance — Specified ripple ratings at both low and high frequencies (1.1 A at 120 Hz; 1.65 A at 50 kHz) give designers quantifiable parameters for thermal and ripple budgeting.
• Clear Endurance and Shelf-Life Criteria — Datasheet-defined limits for capacitance change, tan δ, and leakage after endurance and shelf-life tests support robust design validation.
• RoHS Compliance — Meets current RoHS requirements for use in regulated markets and products.
