LNUN7472MSEHBN

The LNUN7472MSEHBN is a screw‑terminal aluminum electrolytic capacitor in a radial can package designed for high‑voltage industrial power applications. It provides 4.7 mF (4700 µF) capacitance at a rated DC voltage of 525 V and is optimized for inverter and regenerative circuits that require high ripple handling and fast charge–discharge capability.

Built for elevated operating conditions, the capacitor is specified for –40 °C to +105 °C operation and a 5000‑hour load life at 105 °C when subjected to rated ripple current. The LNU series offers a high‑voltage, smaller footprint alternative to larger high‑voltage parts while maintaining robust electrical endurance.

Key Features

• Capacitance & Tolerance — 4.7 mF (4700 µF) with ±20% tolerance (measured at 120 Hz, 20 °C).
• High Rated Voltage — Rated for DC 525 V, supporting high‑voltage inverter and regenerative applications.
• Temperature & Lifetime — Rated for operation from –40 °C to +105 °C with a specified load life of 5000 hours at 105 °C under rated ripple current.
• Ripple Current Capability — 15.2 A at 120 Hz and 21.28 A at 100 kHz, enabling sustained performance under AC ripple loads.
• Screw Terminal Package — Radial can with screw terminals and M5 bolt nominal fastening for secure electrical and mechanical connections in field and factory installations.
• Charge–Discharge Endurance — Designed to withstand high‑speed charge–discharge cycles; the series is specified for endurance over millions of cycles per datasheet charge–discharge tests.
• Electrical Robustness — Leakage current limits after initial application are specified as not more than 3√(C·V) µA or 5 mA (whichever is smaller); insulation resistance and voltage‑proof tests are defined between terminal and bracket.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing for high‑voltage inverter front ends and DC link circuits.
• Inverter Drives — Support for motor drive inverter circuitry including AC servomotor systems that require regenerative handling.
• Regenerative Energy Circuits — Handling of high‑frequency regenerative voltages and rapid charge–discharge cycles in energy recovery applications.
• General High‑Voltage Filtering — Use where polarized, high‑voltage, high‑ripple capacitors are needed for filtering and decoupling in industrial electronics.

Unique Advantages

• High‑Voltage in a Compact Form: 525 V rating delivers high DC voltage capability while the LNU series is specified as smaller than comparable LNT parts, helping reduce space in power assemblies.
• Designed for High Ripple and Fast Cycling: Specified ripple current values at 120 Hz and 100 kHz and charge–discharge endurance make it suitable for inverter and regenerative loads.
• Robust High‑Temperature Life: 5000 hours at 105 °C under rated ripple current provides predictable performance and life in demanding thermal environments.
• Secure Termination for Field Use: Screw terminals with M5 fastening support reliable electrical connections and ease of installation or replacement.
• Measured Electrical Limits: Defined leakage current, insulation resistance, and voltage‑proof criteria provide verifiable performance parameters for design validation.
• RoHS Compliance: Meets applicable RoHS directives for environmental and regulatory compatibility.
