• Screw Terminal Package — Radial can with screw terminals for secure, low-impedance high-current connections suited to industrial assemblies.
• High Ripple Current — 26.3 A at 120 Hz and 36.82 A at 100 kHz, enabling sustained operation under significant AC ripple and high-frequency switching conditions.
• Temperature Range & Lifetime — Rated for –40 °C to +85 °C with a load life of 5000 hours when ripple current is applied at 85 °C.
• Smaller-sized, High Performance — Specified as smaller-sized and higher ripple current than LNX/LNK series components to save board space while maintaining performance.
• Charge–Discharge Endurance — Qualified for extensive charge–discharge stress (50 million cycles at ΔV = rated voltage × 0.3, 3 Hz) to withstand repeated high-speed switching.
• Leakage, Insulation and Voltage Proof — Leakage current after 5 minutes ≤ 3√V µA or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket.
• Tolerance & Polarization — Polarized capacitor with ±20% capacitance tolerance at 120 Hz, 20 °C.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Dimensions — Size dimensions L: 9 × D: 9 cm with a seated height maximum of 3.543 inch, facilitating layout planning for power assemblies.

Typical Applications

• Industrial inverter power supplies — Bulk energy buffering and ripple smoothing in inverter front-ends and DC bus applications.
• AC servomotor regenerative circuits — Handles high-frequency regenerative voltages and fast charge–discharge events in motor drive systems.
• General inverter systems — Supports high ripple and high-frequency switching found in general-purpose inverter topologies.
• High-speed charge–discharge loads — Suited to circuits that require frequent, rapid energy transfer cycles due to proven charge–discharge endurance.

Unique Advantages

• High ripple-current handling: Measured ripple specs (26.3 A at 120 Hz, 36.82 A at 100 kHz) reduce thermal stress and support heavy AC loading in power electronics.
• Compact for the class: Marketed as smaller-sized than LNX/LNK series alternatives, enabling tighter packaging without sacrificing ripple capability.
• Long load life under stress: 5000 hours at 85 °C with applied ripple current provides predictable service life for continuous industrial operation.
• Designed for fast switching: Endurance validated for 50 million charge–discharge cycles, matching the needs of high-speed switching and regenerative applications.
• Robust connection method: Screw-terminal radial can design offers secure electrical and mechanical termination for high-current assemblies.
• Standards-aligned safety margins: Defined leakage, insulation resistance and voltage proof specifications support reliable integration into industrial systems.
