LNR1K334MSEN

The LNR1K334MSEN from Nichicon is an LNR-series aluminum electrolytic capacitor in a screw-terminal, radial can package designed for general-purpose power applications. It provides large bulk capacitance (330,000 µF) at a rated voltage of 80 V with screw terminal mounting for robust electrical and mechanical connections.

Key value propositions include high ripple-current capability (31.8 A at 120 Hz / 36.57 A at 100 kHz), a 5000-hour endurance rating at 85°C, and a wide operating temperature range of −40°C to +85°C, making it suitable for demanding DC link, bulk energy storage, and power smoothing roles.

Key Features

• Core Capacitance & Voltage — 330,000 µF (330 mF) nominal capacitance with an 80 V rated voltage and ±20% tolerance for large bulk energy storage and DC filtering.
• High Ripple Current Performance — Rated ripple current of 31.8 A at 120 Hz and 36.57 A at 100 kHz to support high AC components on DC rails.
• Endurance & Temperature Range — 5000 hours rated life at 85°C and an operating temperature range of −40°C to +85°C for extended field reliability under elevated temperature conditions.
• Leakage and Loss Characteristics — Specified leakage current of 5000 µA and tanδ up to 0.4, providing defined loss and leakage behavior for system design and thermal planning.
• Rugged Mechanical Package — Screw terminal, radial can construction in a φ100 × 250 mm body size (φ100×250L) with M8 bolt terminals and 3-leg mounting bracket as standard for secure mounting and high-current connections.
• Compliance & Production — RoHS-compliant and available in mass production packaging (cardboard packing) to support volume procurement and manufacturing workflows.

Typical Applications

• Power Supplies and DC Link Filtering — Bulk energy storage and smoothing where 330,000 µF at 80 V and significant ripple current capability are required to stabilize DC rails.
• Industrial Power Electronics — Energy buffering and decoupling in converters and inverters that demand sustained ripple handling and long endurance at elevated temperatures.
• UPS and Energy Storage Systems — Bulk capacitance for hold-up and transient suppression in uninterruptible power supplies and energy-storage subsystems.

Unique Advantages

• Massive Bulk Capacitance: 330,000 µF delivers substantial energy storage in a single component, reducing the number of parallel capacitors needed for large DC-link requirements.
• High Ripple-Current Rating: 31.8 A (120 Hz) and 36.57 A (100 kHz) ratings enable this capacitor to handle significant AC stress, supporting robust power-conditioning designs.
• Long Endurance at Elevated Temperature: 5000 hours at 85°C provides predictable lifetime performance for designs exposed to continuous high-temperature operation.
• Robust Screw-Terminal Mechanical Design: M8 screw terminals and a 3-leg bracket (standard for φ100 body) ensure secure electrical connections and mechanical stability in high-current installations.
• Clear Electrical Characteristics: Defined leakage current (5000 µA) and tanδ (0.4) facilitate accurate thermal and loss budgeting in system-level designs.
• RoHS Compliance and Production-Ready Packaging: RoHS status and cardboard packing support regulatory needs and volume manufacturing logistics.
