LNR1H224MSEN

The LNR1H224MSEN from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNR series designed for general‑purpose power applications. It provides very large capacitance (220,000 µF) at a 50 V rating in a radial can with screw terminals for secure, high‑current connections.

Key value is substantial bulk energy storage combined with high ripple handling and extended endurance: rated for operation from −40 °C to 85 °C with a 5,000‑hour endurance at 85 °C and RoHS compliance for environmental compatibility.

Key Features

• Electrical capacity & rating — 220,000 µF (220 mF) rated at 50 V with ±20% capacitance tolerance (120 Hz, 20 °C), delivering large bulk capacitance for power circuits.
• High ripple current capability — Ripple current ratings of 20.3 A at 120 Hz and 23.34 A at 100 kHz support demanding ripple conditions in power systems.
• Endurance & temperature range — Designed for operation from −40 °C to 85 °C with an endurance specification of 5,000 hours at 85 °C under rated bias and ripple current.
• Screw‑terminal, radial can package — Screw terminal mounting and radial can construction (φ90 × 140L, L: 14 cm × D: 9 cm) for robust mechanical and electrical connections; series documentation indicates M5 nominal terminal hardware for φ90 sizes.
• Leakage and loss characteristics — Specified leakage current of 5,000 µA and tan δ of 0.75 provide measurable dielectric performance for design planning.
• Compliance & packing — RoHS compliant and supplied in cardboard packing; available in mass production quantities.

Typical Applications

• General‑purpose power electronics — Bulk capacitance and 50 V rating make this capacitor suitable for general‑purpose filtering and energy storage in power circuits where large capacitance is required.
• Industrial power systems — Screw‑terminal mounting and high ripple current ratings support robust connections and continuous ripple handling in industrial power modules.
• Power supply bulk filtering — High capacitance with defined leakage and tan δ characteristics helps stabilize DC rails and smooth transient loads in power supplies.

Unique Advantages

• Substantial bulk energy storage: 220,000 µF at 50 V provides large capacitance in a single component, reducing part count for high‑capacity designs.
• High ripple tolerance: Rated ripple currents of 20.3 A (120 Hz) and 23.34 A (100 kHz) enable reliable performance under heavy AC ripple conditions.
• Extended endurance at elevated temperature: 5,000 hours at 85 °C under rated conditions supports longer service life in thermally stressed installations.
• Secure mechanical and electrical termination: Screw‑terminal, radial can construction (φ90 × 140L) facilitates robust, low‑impedance connections for high‑current applications.
• Measured dielectric characteristics: Specified leakage current (5,000 µA) and tan δ (0.75) provide predictable behavior for design validation and modeling.
• Regulatory compatibility: RoHS compliance supports use in regions and assemblies that require lead‑free, restricted‑substance control.
