Designed for continuous operation between −40 °C and +85 °C, this polarized capacitor emphasizes high ripple handling, long ripple-load life and robust charge–discharge endurance for demanding industrial use.

Key Features

• Capacitance & tolerance — 3300 µF nominal with ±20% tolerance (measured at 120 Hz, 20 °C).
• Rated Voltage — 350 V DC rating, suitable for inverter and high-voltage power stages.
• Screw terminal mounting — Radial can with screw terminals for secure electrical and mechanical connection in power assemblies.
• High ripple-current capability — 13.6 A at 120 Hz and 19.04 A at 100 kHz, enabling effective smoothing under heavy AC ripple and high-frequency conditions.
• Long ripple-life endurance — Specified load life of 5000 hours when subjected to rated ripple current at 85 °C.
• Wide operating temperature — Rated for operation from −40 °C to +85 °C.
• Charge–discharge endurance — Endurance for high-speed charge–discharge cycles (50 million cycles specified in series datasheet under defined test conditions).
• Electrical robustness — Leakage current specified after 5 minutes’ rated voltage application (≤ 3√V µA or 5 mA, whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V for 1 minute between terminal and bracket.
• RoHS compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).
• Compact physical footprint — Package dimensions L: 11.5 × D: 5.1 cm, offering high ripple performance in a reduced size compared with previous LNX/LNK series designs.

Typical Applications

• Industrial inverters — Bulk energy storage and ripple smoothing in inverter power supplies and drive electronics.
• AC servomotor drives — Handling high-frequency regenerative voltages and smoothing during bidirectional energy flow.
• Regenerative power systems — Coping with high-speed charge–discharge cycles in systems that recover and redistribute energy.
• High-frequency power circuits — Filtering and energy buffering where elevated ripple currents at 100 kHz are present.

Unique Advantages

• Elevated ripple handling: Rated ripple currents of 13.6 A (120 Hz) and 19.04 A (100 kHz) enable sustained operation under heavy AC ripple and high-frequency stress.
• Long-life under ripple load: 5000-hour load-life specification at 85 °C with applied ripple current provides predictable service life for continuous industrial use.
• Designed for fast charge–discharge: Series-specified endurance for millions of charge–discharge cycles supports regenerative and dynamic power applications.
• Robust electrical safety margins: Insulation resistance and voltage-withstand testing between terminal and bracket add assurance for system-level isolation and reliability.
• Space-efficient design: Delivers 3300 µF at 350 V in a smaller package footprint (L: 11.5 × D: 5.1 cm), helping optimize board and chassis layouts.
• Regulatory compliance: RoHS compliance supports use in regulated industrial and commercial products.
