LNU2H272MSEHBB

The LNU2H272MSEHBB from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNU series, offering 2.7 mF (2700 µF) capacitance at a 500 V rating. Engineered for industrial power electronics, it targets inverter circuitry, high‑frequency regenerative circuits and other applications that require high voltage handling and robust charge‑discharge performance.

This radial can, screw‑terminal device is designed for demanding thermal and electrical environments: it operates from −40 °C to +105 °C, supports a rated voltage range up to DC 525 V, and provides long load life and high ripple current capability for reliable system operation.

Key Features

• Capacitance & Voltage — Rated capacitance 2.7 mF (2700 µF) with a nominal rated voltage of 500 V (rated voltage range up to DC 525 V).
• Temperature and Lifetime — Wide operating range from −40 °C to +105 °C with a specified load life of 5000 hours at 105 °C under applied ripple current.
• Screw Terminal, Radial Can Package — Robust screw‑terminal mounting and radial can construction for secure electrical and mechanical connections; brackets are supplied separately.
• High Ripple Current Capability — Supports 9.6 A ripple current at 120 Hz and 13.44 A at 10 kHz for demanding AC and high‑frequency load conditions.
• High‑Frequency and Charge‑Discharge Endurance — Designed to cope with high‑speed charge/discharge loading and high‑frequency regenerative voltage typical of inverter and servomotor systems.
• Leakage, Insulation and Voltage Withstand — Leakage current specification: after 5 minutes ≤ 3√(C·V) µA or 5 mA (whichever is smaller) at 20 °C; 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 Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies (Inverter Circuitry) — Energy storage and smoothing for inverter front‑ends and power conversion stages.
• AC Servomotor Regenerative Circuits — Handles high‑frequency regenerative voltages and frequent charge/discharge cycles in servo drives.
• General Inverter Systems — Bulk capacitance and ripple handling for inverters used in industrial motion control and variable speed drives.

Unique Advantages

• High Voltage in a Compact LNU Package — 500 V rating (series rated up to DC 525 V) provides the voltage headroom required by industrial inverter and regenerative systems while keeping package size smaller than comparable LNT options.
• Designed for High‑Stress Cycling — Specified endurance for charge‑discharge behavior (50 million cycles per datasheet conditions) and a 5000‑hour load life at 105 °C support long service in high‑cycle applications.
• Strong Ripple Performance — Dual ripple ratings at 120 Hz and 10 kHz allow designers to quantify thermal and electrical stress for both low‑ and high‑frequency usage scenarios.
• Robust Electrical Safety Margins — Defined leakage current limits, insulation resistance >100 MΩ, and AC 2500 V dielectric proofing between terminal and bracket give measurable safety and diagnostic criteria for system integration.
• Industry Compliance — RoHS conformity helps meet regulatory requirements for industrial equipment manufacturing and deployment.
