LNR1H223MSE

The LNR1H223MSE is a screw‑terminal aluminum electrolytic capacitor by Nichicon, rated 50 V with 22,000 µF (22 mF) capacitance and ±20% tolerance. It is designed for general‑purpose applications that require large bulk capacitance in a rugged, screw‑terminal package.

Key performance attributes include a high permissible ripple current at both low and high frequencies, a long endurance specification of 5,000 hours at 85°C, low‑temperature operation down to –40°C, and RoHS compliance. The part is supplied in a radial can with screw terminals (φ35 × 100L).

Key Features

• High capacitance: 22,000 µF (22 mF) nominal capacitance provides substantial bulk energy storage and smoothing within a single component.
• Rated voltage: 50 V rating suitable for mid‑voltage power rails and general‑purpose DC applications.
• Ripple current capability: 6.1 A at 120 Hz (low frequency) and 7.015 A at 100 kHz (high frequency) to support sustained ripple handling across common switching and line‑frequency conditions.
• Endurance and temperature performance: 5,000 hours life at 85°C and an operating range of –40°C to 85°C for reliable operation in a wide range of thermal environments.
• Electrical characteristics: Specified leakage current of 3,140 µA and a tangent of loss angle (tan δ) of 0.25 for predictable electrical behavior.
• Screw‑terminal package: Radial can with screw terminals (φ35 × 100L) for secure, low‑impedance connections in chassis or power assemblies.
• Compliance: RoHS compliant, supporting regulatory requirements for restricted substances.

Typical Applications

• General‑purpose power systems: Bulk capacitance and ripple handling for general power supply and energy‑storage functions where a screw‑terminal mounting is preferred.
• Industrial assemblies: Use in equipment that requires a robust, serviceable terminal connection and long endurance at elevated temperatures.
• Chassis‑mounted power modules: Suitable where radial can screw terminals and high capacitance are needed for filtering and smoothing within a compact footprint (φ35 × 100L).

Unique Advantages

• Large single‑component capacitance: 22,000 µF reduces part count compared with multiple smaller capacitors, simplifying BOM and layout.
• High ripple current at multiple frequencies: Rated ripple current values at 120 Hz and 100 kHz address both line‑frequency and high‑frequency ripple scenarios.
• Long endurance at elevated temperature: 5,000 hours at 85°C supports extended service life in continuous‑operation environments.
• Secure screw‑terminal connections: Screw terminals provide low‑impedance, mechanically robust terminations suitable for higher current paths and field serviceability.
• Wide operating temperature range: –40°C to 85°C allows deployment across a broad set of thermal conditions without derating beyond the specified limits.
• Regulatory readiness: RoHS compliance assists in meeting environmental and procurement requirements.
