LNR1V334MSEB

The LNR1V334MSEB from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNR series, offering very high bulk capacitance for general-purpose power designs. It is a polarized, radial can with screw terminals designed for secure electrical and mechanical connections in systems that require large energy storage at 35 V.

Built for standard 85°C operation and mass-production supply, this part combines high capacitance (330,000 µF) with defined endurance and ripple-handling characteristics to support bulk smoothing and energy-buffering in industrial and general-purpose power electronics.

Key Features

• High Capacitance: 330,000 µF (330 mF) nominal capacitance to provide substantial bulk energy storage in compact screw-terminal packaging.
• Rated Voltage and Polarization: 35 V rated voltage; polarized construction suitable for DC bias applications.
• Operating Temperature Range: Specified for –40 °C to +85 °C (applicable for the 10–100 V rating range), supporting designs across common ambient conditions.
• Endurance and Reliability: Rated life of 5000 hours at 85 °C under DC bias plus rated ripple current; capacitance change guaranteed within ±15% after endurance test per series specification.
• Leakage and Loss Characteristics: Specified leakage current 5000 µA (5 mA); series datasheet limit references ≤ 3√CV (µA) or 5 mA after 5 minutes at 20 °C. Maximum tanδ specified at 0.75 (measured at 120 Hz, 20 °C).
• Ripple Current Capability: 24.8 A at 120 Hz and 28.52 A at 100 kHz, enabling effective handling of AC ripple in power-filtering applications.
• Robust Mechanical Package: Radial can with screw terminals and standard 3-leg bracket mounting for larger diameters; nominal bolt size for φ76.2 is M5 as specified for the series.
• Packaging & Production: Cardboard packing and listed for mass production supply; RoHS compliant.

Typical Applications

• General-purpose power systems: Large bulk capacitance and screw-terminal connections make this part suitable for DC power supplies and systems that require stable bulk energy storage at 35 V.
• Power filtering and smoothing (general-purpose): High ripple current ratings and large capacitance support AC ripple reduction and DC bus smoothing in general-purpose electronics.
• Energy buffering for general-purpose equipment: The long-life endurance rating (5000 h at 85 °C) and high capacitance allow use where sustained energy buffering is required in standard industrial and commercial designs.

Unique Advantages

• Exceptional bulk capacitance: 330,000 µF provides a high energy-storage density for applications needing large DC-side capacitance.
• Screw-terminal security: Screw terminals and M5 nominal bolt size for the φ76.2 body enable robust, low-resistance connections and secure mounting in larger assemblies.
• High ripple handling: Specified ripple current values of 24.8 A (120 Hz) and 28.52 A (100 kHz) support demanding ripple environments without immediate degradation.
• Defined endurance: 5000-hour life at 85 °C with limits on capacitance change (±15%), tanδ, and leakage current provides predictable long-term behavior under rated conditions.
• Temperature performance: Rated for –40 °C to +85 °C for the applicable voltage range, with defined impedance increase limits at low temperature per series specifications.
• Regulatory and production readiness: RoHS compliant and supplied in cardboard packing for mass-production environments.
