LNR1K333MSEB

The LNR1K333MSEB is an aluminum electrolytic capacitor in a screw-terminal, radial can package designed for general-purpose power applications that demand high capacitance at elevated voltage. It provides 33,000 µF of capacitance at an 80 V rating with a screw-terminal mounting style and robust mechanical dimensions (φ51 × 120L).

Key performance attributes include high ripple-current capability, a long endurance rating under elevated temperature, and a wide operating temperature range—features that support demanding power supply and energy-buffering designs.

Key Features

• High Capacitance — 33,000 µF (33 mF) nominal capacitance with ±20% tolerance (120 Hz, 20°C) for large bulk energy storage and smoothing.
• 80 V Rated Voltage — 80 V DC rated voltage suitable for higher-voltage power rails and DC-link applications requiring elevated working voltage.
• High Ripple Current Performance — Low-frequency ripple current of 9.2 A (120 Hz) and high-frequency ripple current of 10.58 A (100 kHz) to handle substantial AC ripple under load.
• Screw Terminal Package — Radial can with screw terminals (M5 nominal bolt for φ51 body) for secure, low-impedance connections in power assemblies; package size φ51 × 120L.
• Endurance at Elevated Temperature — Rated for 5000 hours at 85°C under DC bias plus rated ripple current; after endurance the capacitance change remains within ±15% and leakage current meets initial specification limits.
• Electrical Loss and Leakage — Measured tan δ 0.2 (120 Hz, 20°C) with a listed leakage current of 4,870 µA, providing predictable loss characteristics for design calculation.
• Wide Operating Temperature — Specified for –40°C to +85°C operation to accommodate a broad range of environmental conditions.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.
• Packaging & Availability — Supplied in cardboard packing and currently in mass production.

Typical Applications

• General-purpose power filtering — Bulk smoothing and energy buffering where 33,000 µF at 80 V is required to stabilize DC rails.
• Industrial power supplies — Use in power-supply output stages or input filters that demand high ripple-current capability and screw-terminal connections.
• DC-link and power conversion systems — Local energy storage for converters and inverters where high capacitance and elevated ripple handling are important.
• Backup filtering in control systems — Energy buffering and filtering for control electronics and auxiliary power circuits requiring long endurance at 85°C.

Unique Advantages

• Large energy storage in a compact package: 33,000 µF at 80 V provides significant bulk capacitance for DC-link and smoothing applications without complex parallel arrangements.
• Robust ripple handling: High low- and high-frequency ripple current ratings (9.2 A at 120 Hz, 10.58 A at 100 kHz) reduce thermal stress under heavy AC loading.
• Durability under thermal stress: 5000-hour endurance at 85°C with controlled capacitance shift (±15%) supports longer service intervals and predictable life modeling.
• Secure electrical and mechanical connection: Screw-terminal, radial can construction enables low-impedance connections and reliable mounting for power assemblies.
• Predictable electrical characteristics: Specified tan δ and measured leakage current provide data for accurate loss and standby current budgeting.
• Regulatory alignment: RoHS compliance supports deployment in regions requiring restricted-substance adherence.
