LNR1H334MSEB

The LNR1H334MSEB is a Nichicon LNR series screw‑terminal aluminum electrolytic capacitor rated 50 V with 330,000 µF (330 mF) capacitance. It is a polarized, radial can design with screw terminals intended for general‑purpose power applications that require large bulk capacitance and secure, low‑impedance connections.

Built for continuous operation up to 85°C with a 5,000 hour endurance at 85°C, this part delivers high ripple handling and long‑term stability in systems operating between –40°C and +85°C.

Key Features

• High Capacitance & Voltage: 330,000 µF at 50 V provides substantial bulk energy storage and smoothing for power rails and DC bus applications.
• Screw‑Terminal Package: Radial, can‑style case with screw terminals (φ90 × 170 mm body) for robust, low‑resistance terminations and easy field installation.
• Endurance Specified: Rated for 5,000 hours at 85°C with limits on capacitance change (within ±15%), tan δ (≤175% of initial spec), and leakage current (≤ initial specified value) after endurance testing.
• Leakage Current Defined: Specified leakage current 5,000 µA; aligns with the series leakage criteria after 5 minutes’ application of rated voltage at 20°C.
• High Ripple Capability: Ripple current of 25.3 A at 120 Hz and 29.09 A at 100 kHz supports demanding AC ripple and transient workloads.
• Wide Operating Temperature Range: –40°C to +85°C for stable performance across common industrial environments.
• Capacitance Tolerance & Loss: ±20% tolerance at 120 Hz, 20°C; tan δ provided (0.75) for loss‑angle reference in filter and decoupling designs.
• RoHS Compliant: Conforms to RoHS requirements per product data.

Typical Applications

• Power Supply Bulk Filtering: Large bulk capacitance smooths DC bus voltage and reduces ripple in industrial and telecom power supplies.
• Energy Storage for Hold‑Up: Provides stored energy for short hold‑up intervals during transient events or brief input interruptions.
• Inverter and Motor Drive DC Link: High capacitance and rated ripple current support DC link smoothing in motor drives and power conversion equipment.
• Industrial Power Electronics: Suitable for general‑purpose industrial systems requiring durable, high‑capacitance components with secure screw connections.

Unique Advantages

• Large Bulk Capacity: 330 mF at 50 V reduces the need for parallel capacitors and simplifies BOM for high‑energy filtering.
• Secure, Serviceable Connections: Screw terminals offer reliable mechanical and electrical contact for heavy‑current applications and field servicing.
• Specified Endurance & Stability: 5,000 hour rating at 85°C with quantified limits on capacitance change, tan δ, and leakage supports predictable lifetime planning.
• High Ripple Handling: Measured ripple currents (25.3 A at 120 Hz, 29.09 A at 100 kHz) enable use in designs with significant AC ripple or switching transients.
• Wide Ambient Range: –40°C to +85°C operation covers a broad range of industrial environmental conditions.
• Clear Specification Basis: Leakage current and loss‑angle references follow the LNR series definitions for measurement conditions, aiding engineering validation.
