LNR1V334MSEN

The LNR1V334MSEN is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNR series designed for general‑purpose power applications. It delivers very high capacitance (330000 µF / 330 mF) at a rated voltage of 35 V in a radial can with screw terminals for robust electrical and mechanical connections.

Engineered for continuous operation up to 85°C with a 5000‑hour endurance rating, this component is intended for designs that require bulk energy storage and high ripple current handling in a compact, mountable package.

Key Features

• Capacitance & Tolerance — 330000 µF (330 mF) nominal with tolerance of −20% to +20% at 120 Hz, 20°C.
• Rated Voltage — 35 V DC rating suitable for many medium‑voltage power circuits.
• Screw Terminal Mounting — Radial can with screw terminals provides secure, low‑impedance connections for heavy current paths.
• High Ripple Current Capability — Low‑frequency ripple current of 24.8 A at 120 Hz and high‑frequency ripple current of 28.52 A at 100 kHz enable effective handling of both LF and HF ripple loads.
• Endurance & Temperature — Rated for 5000 hours at 85°C; operational temperature range −40°C to +85°C.
• Loss Tangent & Leakage — tanδ (DF) specified at 0.75 (measured at 20°C, 120 Hz) and leakage current listed as 5000 µA.
• Package & Dimensions — Body diameter φ76.2 mm with length 140 mm (L: 14 cm × D: 7.62 cm); supplied with cardboard packing for shipment.
• Compliance — RoHS compliant.

Typical Applications

• General‑Purpose Power Filtering — Bulk capacitance for smoothing and energy buffering in general‑purpose power designs where high capacitance and screw‑terminal mounting are required.
• Ripple‑Intensive Circuits — Use where both low‑frequency and high‑frequency ripple currents must be managed reliably, leveraging the specified LF and HF ripple ratings.
• Industrial Power Modules — Suitable for industrial power electronics and modules that need long endurance at elevated temperature (5000 h at 85°C).

Unique Advantages

• Extremely High Bulk Capacitance: 330000 µF provides substantial energy storage in a single component, reducing the need for parallel capacitors.
• Robust Current Handling: Specified LF and HF ripple current ratings (24.8 A @120 Hz, 28.52 A @100 kHz) support applications with significant ripple and switching activity.
• Durability at Elevated Temperature: 5000‑hour endurance at 85°C supports long service life in warm operating environments.
• Secure Mechanical & Electrical Connection: Screw‑terminal radial can simplifies mounting and creates low‑impedance connections for heavy‑current paths.
• Measurable Performance Metrics: Specified tanδ (0.75 at 20°C, 120 Hz) and defined leakage current (5000 µA) allow predictable design tradeoffs for ESR and standby losses.
• Regulatory Compliance: RoHS compliance ensures conformity with lead‑free/regulated material requirements.
