LNR1H333MSEB

The LNR1H333MSEB from Nichicon is a screw-terminal, radial can aluminum electrolytic capacitor in the LNR series designed for general-purpose power applications. It delivers 33,000µF capacitance at a 50V rating in a φ51×70mm package (radial can with screw terminals), combining high bulk capacitance with a robust screw-terminal mounting style.

This part is built for sustained operation up to 85°C with a rated endurance of 5,000 hours at 85°C under DC bias plus rated ripple current. It is RoHS compliant and supplied in cardboard packing for mass-production use.

Key Features

• Capacitance & Voltage — 33,000µF nominal capacitance at a 50V rated voltage with ±20% tolerance (measured at 120Hz, 20°C).
• Thermal Range & Endurance — Operates from −40°C to +85°C with an endurance specification of 5,000 hours at 85°C under rated bias and ripple current.
• Ripple Current Performance — Rated ripple current of 7 A at 120Hz and 8.05 A at 100 kHz, supporting AC ripple handling at both low and high frequencies.
• Leakage & Reliability — Leakage current guaranteed after 5 minutes at 20°C to be not more than 3√(C·V) µA or 5 mA (whichever is smaller); endurance limits cap change to within ±15% after the rated life test.
• Screw Terminal Mounting — Radial can with screw terminals (φ51 body) and M5 nominal bolt diameter for secure, low-resistance connections; standard 3-leg bracket mounting provided for φ51 size.
• Physical & Packaging — Body dimensions approximately 51 mm diameter × 70 mm length (L: 7 × D: 5.1 cm); supplied in cardboard packing for production handling.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk capacitance for smoothing and energy storage in DC power supplies and converters.
• Industrial power electronics — Energy reservoir and ripple absorption where high capacitance and screw-terminals are needed for reliable connections.
• Backup and hold-up circuits — Capacitor energy storage for short-term hold-up in control and auxiliary power modules.

Unique Advantages

• High bulk capacitance at 50V: 33,000µF provides substantial energy storage in a compact φ51×70mm package for designs requiring large capacitance without oversized enclosures.
• Screw-terminal robustness: M5 screw terminals and standard 3-leg bracket for φ51 ensure secure mechanical and electrical connections in production assemblies.
• Dual-frequency ripple ratings: Specified ripple current at both 120Hz and 100kHz supports designs handling low- and high-frequency ripple components.
• Endurance-backed performance: 5,000-hour endurance at 85°C under rated bias and ripple current with defined limits for capacitance change, tan δ and leakage current.
• Measured leakage specification: Leakage after initial application of rated voltage is bounded by 3√(C·V) µA or 5 mA (whichever is smaller), enabling predictable start-up behavior.
• RoHS compliant supply: Manufactured to meet RoHS requirements and supplied for mass-production in cardboard packing.
