LNR2A224MSE

The LNR2A224MSE is an aluminum electrolytic capacitor in a screw-terminal, radial can package designed for high-capacitance, general-purpose power applications. It delivers 220,000 µF at 100 V with a rated operating temperature range of −40°C to 85°C and is specified for 5,000 hours of endurance at 85°C.

Its combination of very high capacitance, substantial ripple-current capability and screw-terminal mounting makes it suitable for bulk energy storage and power smoothing in industrial and heavy-duty electronic systems where secure electrical connections and long-term stability are required.

Key Features

• High Capacitance: 220,000 µF (220 mF) provides large bulk energy storage for smoothing and hold-up in DC power systems.
• 100 V Rated Voltage: Rated for 100 V operation to support higher-voltage power rails and DC link applications.
• Screw Terminal Mounting & Package: Radial, can style with screw terminals (φ100 body) for secure, low‑resistance connections and robust mechanical mounting.
• Ripple Current Performance: Rated ripple current of 32.7 A at 120 Hz and 37.6 A at 100 kHz, enabling handling of significant AC stress on DC bus capacitors.
• Endurance and Stability: Lifetime of 5,000 hours at 85°C with specified limits for capacitance change, tan δ and leakage current after endurance testing.
• Electrical Characteristics: Tolerance ±20%, tan δ up to 0.3, and leakage current specified (5,000 µA listed for this part) for predictable behavior in designs.
• Wide Operating Temperature: −40°C to 85°C rating for use across a broad range of ambient conditions.
• Manufacturing & Packaging: Supplied for mass production in cardboard packing suitable for bulk assembly processes.

Typical Applications

• Power supply bulk smoothing: Large capacitance and high ripple-current ratings make it suitable for smoothing DC rails and supplying transient loads in power supplies.
• DC link and inverter support: 100 V rating combined with high ripple capability fits DC link duties and energy buffering in industrial converters and motor drives.
• Standby and hold-up energy storage: Use where extended hold-up or energy reserve is required on higher-voltage systems.

Unique Advantages

• Substantial energy density: 220,000 µF at 100 V provides significant bulk capacitance in a single component, reducing the number of parallel capacitors required.
• Robust electrical connections: Screw terminal design enables reliable, low-impedance connections and easier installation or replacement in heavy-current systems.
• Designed for long-term operation at elevated temperature: 5,000-hour endurance rating at 85°C offers predictable lifetime performance in demanding thermal environments.
• Quantified ripple handling: Published ripple current values at 120 Hz and 100 kHz allow designers to size capacitors against expected AC stress with confidence.
• Wide ambient range: −40°C to 85°C operating range supports deployment across varied environmental conditions without derating beyond specified limits.
• Production-ready packaging: Cardboard packing and mass-production availability streamline procurement and assembly for volume programs.
