LNR1H684MSE

The LNR1H684MSE is a screw-terminal, radial can aluminum electrolytic capacitor offering 680000 µF capacitance at a 50 V rating. Designed for general-purpose bulk energy storage and high-current filtering, it pairs very large capacitance with a rugged screw-terminal package suitable for demanding power applications.

Key value points include high ripple-current capability, long endurance at elevated temperature, and a screw-terminal mounting system that supports secure high-current connections for industrial and power-electronics assemblies.

Key Features

• Very high capacitance — 680000 µF (680 mF) provides substantial bulk energy storage for smoothing and hold-up in power systems.
• Rated voltage — 50 V nominal rating for medium-voltage power rails and energy storage tasks.
• Rugged screw-terminal package — Radial can with screw terminals and M8 nominal bolt for the φ100 body diameter supports secure, high-current termination and robust mechanical fastening.
• High ripple current capability — 36 A at 120 Hz and 41.4 A at 100 kHz, enabling effective AC ripple handling in high-power supplies and converters.
• Wide operating temperature and endurance — Rated for –40 °C to +85 °C with an endurance specification of 5000 hours at 85 °C under rated DC bias plus rated ripple current.
• Leakage and tolerance specifications — Capacitance tolerance ±20% (at 120 Hz, 20 °C); leakage current after 5 minutes is ≤ 3√CV (μA) or 5 mA, whichever is smaller.
• Polarized construction — Designed for DC energy storage applications where polarity is observed.
• Large physical footprint — Body dimensions approximately φ100 × 250 mm (L: 25 × D: 10 cm) for high-capacitance, high-energy applications.

Typical Applications

• Industrial power supplies — Provides bulk capacitance and ripple handling for large DC bus and supply smoothing in industrial equipment.
• Power conversion and motor drives — Supports DC-link energy storage and transient buffering where high ripple currents and large capacitance are required.
• Energy storage and UPS systems — Used for hold-up and short-term energy delivery in uninterruptible power and backup systems.
• High-power electronics cabinets — Screw-terminal mounting and robust mechanical design simplify integration into rack-mounted and cabinet-level power assemblies.

Unique Advantages

• Massive energy capacity: 680000 µF delivers significant stored energy per capacitor, reducing the need for many smaller units and simplifying BOM and layout.
• High ripple handling: Rated ripple currents of 36 A (120 Hz) and 41.4 A (100 kHz) minimize heating and extend service life under demanding AC stress.
• Service life at elevated temperature: 5000 hours at 85 °C under rated bias and ripple provides predictable endurance data for reliability planning.
• Secure, high-current termination: Screw-terminal and M8 bolt hardware for the φ100 body enable reliable electrical and mechanical connections in high-current installations.
• Designed for wide thermal range: –40 °C to +85 °C operating window accommodates many industrial and commercial environments.
• RoHS compliant: Meets RoHS requirements for environmental regulatory preference.
