LNR1E224MSE

The LNR1E224MSE is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNR series, offering very high capacitance (220,000 µF) at a 25 V rating in a radial can with screw terminals. It is intended for general-purpose power applications that require large bulk capacitance, high ripple handling and robust mounting.

Key value propositions include high ripple-current capability (specified for both low and high frequency), a 5000-hour endurance rating at 85°C, and a wide operating temperature range of −40°C to 85°C—delivering stable bulk energy storage and smoothing under sustained DC bias and ripple loading.

Key Features

• High Capacitance — 220,000 µF (220 mF) nominal capacitance with tolerance ±20% at 120 Hz, 20°C, providing substantial bulk energy storage.
• Rated Voltage — 25 V DC rated voltage suitable for mid-voltage power rails and DC-link applications.
• High Ripple Current Handling — Low-frequency ripple current 18.9 A (120 Hz) and high-frequency ripple current 21.73 A (100 kHz), enabling effective smoothing under significant AC ripple conditions.
• Endurance and Reliability — Life rating of 5000 hours at 85°C; after the specified life with DC bias plus rated ripple current, capacitance change remains within ±15%, tan δ remains within 175% of initial, and leakage current remains at or below the initial specified value.
• Electrical Loss Characteristic — tan δ (loss tangent) specified at 0.65 (measured at 20°C, 120 Hz), providing a verifiable dissipation factor for design calculations.
• Operating Temperature Range — −40°C to 85°C, supporting a broad range of ambient conditions for general-purpose equipment.
• Screw-Terminal Mounting and Mechanical Details — Radial can with screw terminals and standard 3-leg mounting bracket for body diameters φ51 or larger; body dimensions φ63.5 × 120 L (L: 12.0 cm × D: 6.35 cm). Nominal terminal bolt size for φ63.5 is M5.
• Leakage Current Specification — Specified leakage current up to 5,000 µA.
• RoHS Compliant & Packaging — RoHS-compliant device supplied in cardboard packing for bulk handling.

Typical Applications

• General-purpose power systems — Bulk energy storage and DC filtering where high capacitance and sustained ripple handling are required.
• Power supply smoothing — Buffering and smoothing of DC rails subject to continuous ripple current and DC bias at moderate voltages.
• Industrial and equipment power modules — Use in general-purpose industrial electronics that need durable, high-capacitance components with screw-terminal connections for secure wiring and serviceability.

Unique Advantages

• Substantial bulk capacitance: 220,000 µF provides extended hold-up and smoothing capability compared with lower-capacitance options.
• High ripple-current capability: Rated ripple currents at both 120 Hz and 100 kHz support designs with significant low- and high-frequency ripple content.
• Documented endurance: 5000 hours at 85°C under rated DC bias plus ripple gives predictable aging characteristics and post-life performance limits (capacitance, tan δ, leakage current).
• Robust mechanical mounting: Screw terminals with M5 bolt accommodation and standard 3-leg bracket for φ63.5 units simplify secure installation and maintenance.
• Measured loss characteristics: tan δ specified at 0.65 (20°C, 120 Hz) for accurate thermal and dissipation planning.
• Regulatory compliance: RoHS-compliant construction supports environmental requirements for commercial and industrial products.
