LNR1C224MSE

The LNR1C224MSE is an aluminum electrolytic, screw-terminal capacitor optimized for general-purpose power applications that require large bulk capacitance. It is a polarized radial can with screw terminals designed for robust panel or bracket mounting and provides high-capacity energy storage at a rated voltage of 16 V.

Key value propositions include very high capacitance (220000 µF), long-term endurance under elevated temperature, and mounting hardware suited to larger-diameter electrolytic cans — useful where high ripple handling and durable mechanical connections are needed.

Key Features

• High Capacitance: 220000 µF (220 mF) bulk capacitance for energy storage and smoothing in power systems.
• Rated Voltage: 16 V nominal working voltage for low-voltage DC bus applications.
• Screw-Terminal Construction: Radial can with screw terminals provides secure electrical connections and mechanical robustness for panel or bracket mounting.
• Endurance at Elevated Temperature: 5000 hours at 85°C with D.C. bias plus rated ripple current; after endurance the capacitance change remains within ±15% and leakage current stays at or below initial specified value.
• Operating Temperature Range: –40°C to +85°C suitable for a wide range of general-purpose industrial environments.
• Ripple Current Capability: 15.6 A at 120 Hz and 17.94 A at 100 kHz, enabling effective AC ripple handling when used with the appropriate DC bias.
• Leakage Current Specification: After 5 minutes’ application of rated voltage, leakage current is ≤ 3√(C·V) µA or 5 mA, whichever is smaller (at 20°C), per datasheet specification.
• Physical Size & Mounting: Body diameter φ51 mm by 120 mm length (L: 12 cm × D: 5.1 cm); φ51 units are furnished with 3-leg brackets as standard and use M5 terminal bolts per the series drawing.
• Tolerance & Polarization: Capacitance tolerance ±20% at 120 Hz, 20°C; polarized construction.
• RoHS Compliant: Meets RoHS requirements as specified in product data.

Typical Applications

• Power supply bulk storage: Large-capacitance energy reservoir for smoothing and bulk storage on low-voltage DC rails.
• Industrial power modules: Bulk filtering and ripple absorption where high ripple current capability and screw-terminal connections are required for reliable wiring.
• Energy buffering: Backup and hold-up applications that need high capacitance and endurance at elevated temperature.

Unique Advantages

• Exceptional bulk energy capacity: 220000 µF provides substantial charge storage in a single component, reducing the need for parallel arrays.
• Robust electrical and mechanical connections: Screw-terminal package and standard 3-leg bracket (for φ51) accommodate secure mounting and high-current terminations.
• Proven high-temperature endurance: Rated for 5000 hours at 85°C under DC bias plus rated ripple current with specified limits on capacitance change and leakage.
• High ripple handling: Specified ripple currents at both low (120 Hz) and high (100 kHz) frequencies support diverse power-conversion topologies.
• Design predictability: Datasheet-established leakage current formula and tolerance values enable engineers to model performance precisely.
• Regulatory compliance: RoHS status supports use in assemblies targeting restricted-substance compliance.
