LNR1V334MSE

The LNR1V334MSE is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNR series, offering 330,000 µF nominal capacitance at a 35 V rating. It is a radial, can-style, polarized capacitor designed for general-purpose use, combining very large capacitance with robust screw-terminal mounting.

Key value propositions include high ripple-current capability, long endurance at elevated temperature, and a wide operating temperature range—features that address demanding power roles where high bulk capacitance and reliable terminal connections are required.

Key Features

• Capacitance — 330,000 µF (330 mF) nominal with ±20% tolerance (specified at 120 Hz, 20°C).
• Rated Voltage — 35 V DC rating for medium-voltage power designs.
• Screw-Terminal Package — Radial can with screw terminals; φ76.2 mm body diameter with M5 nominal bolt mounting per series dimensioning for large-diameter types.
• High Ripple Current — 24.8 A at 120 Hz (low frequency) and 28.52 A at 100 kHz (high frequency) for demanding ripple conditions.
• Endurance and Temperature Range — Rated for 5000 hours at 85°C; operating temperature −40°C to +85°C.
• Leakage and Loss Characteristics — Specified leakage current up to 5000 µA and a tangent of loss angle (tan δ) of 0.75.
• Form Factor and Packing — Large-format φ76.2 × 140 mm can; supplied in cardboard packing and in mass production status.
• RoHS Compliant — Conforms to RoHS requirements.

Typical Applications

• General-purpose power supply support — Provides large bulk capacitance for smoothing and energy buffering in general-purpose power systems where screw-terminal connections are preferred.
• High-ripple environments — Designed to handle elevated ripple currents at both low and high frequencies as specified (24.8 A at 120 Hz, 28.52 A at 100 kHz).
• Industrial equipment — Large-diameter screw-terminal construction and bracket options (3-leg standard for φ51 and larger) fit installations requiring secure mechanical mounting.

Unique Advantages

• Very high capacitance in a single component — 330,000 µF reduces the need for parallel capacitor arrays when large bulk capacitance is required.
• Robust screw-terminal connection — M5 nominal bolt terminals and radial can packaging provide secure, serviceable electrical connections for heavy-current applications.
• High ripple-current capability — Specified ripple ratings at both 120 Hz and 100 kHz support designs with significant AC stress across the capacitor.
• Designed for sustained elevated-temperature operation — 5000-hour endurance at 85°C supports reliable performance in continuous-duty environments.
• Wide operating temperature range — −40°C to +85°C accommodates a broad range of environmental conditions.
• Production-ready supply — Mass production status and cardboard packing support volume procurement and handling.
