LNR1H334MSE

The LNR1H334MSE is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNR series, specified for general-purpose applications requiring very high capacitance at a 50 V rating. It combines a large 330000 µF capacitance in a radial can with screw terminals and is offered in mass-production cardboard packing.

Key Features

• High Capacitance – 330000 µF (330 mF) nominal capacitance for bulk energy storage and smoothing in general-purpose designs.
• Rated Voltage – 50 V rated voltage suitable for medium-voltage power systems within its specified range.
• Screw Terminal Mounting & Package – Radial can with screw terminals for secure chassis or bracketed mounting; larger diameters are furnished with three-leg brackets as standard.
• Operating Temperature – Specified for –40 °C to +85 °C operation, matching the LNR series standard temperature range for 10–100 V parts.
• Endurance – 5000 hours at 85 °C with DC bias plus rated ripple current; capacitance change remains within ±15% after the endurance test.
• Ripple Current Ratings – 25.3 A at 120 Hz and 29.09 A at 100 kHz, enabling handling of substantial AC ripple under rated conditions.
• Leakage Current Specification – After 5 minutes’ application of rated voltage, leakage current is not more than 3√CV (µA) or 5 mA, whichever is smaller (at 20 °C).
• Tolerance & Polarization – Capacitance tolerance ±20% at 120 Hz, 20 °C; polarized design.
• Physical Size – φ90 × 170L form factor (approximately 9 cm diameter × 17 cm length) for high-density bulk capacitance installations.
• Shelf Life & Reliability – Shelf-life test: after storage at 85 °C for 1000 hours and voltage treatment, capacitance change within ±20% and tan δ within 175% of initial specified value.
• RoHS Compliant – Meets RoHS requirements.

Typical Applications

• General Purpose Electronics – Suited for general-purpose designs that require very large capacitance and a 50 V rating in a screw-terminal package.
• Power Modules and Chassis-Mounted Systems – Screw terminals and standard three-leg bracketing for φ51 or larger diameters support secure mounting in module or chassis assemblies.
• High-Ripple Environments – Use where elevated ripple current capability is required, with specified ripple ratings at 120 Hz and 100 kHz to guide thermal and ripple management.
• Production and Volume Deployments – Cardboard packing and mass-production availability make this part suitable for repeat production runs and volume procurement.

Unique Advantages

• Extremely High Bulk Capacitance: 330000 µF delivers substantial stored energy and smoothing capacity without requiring parallel arrays of smaller capacitors.
• Screw-Terminal Robustness: Screw terminals provide reliable mechanical and electrical connections for chassis- or bracket-mounted installations.
• Documented Endurance: 5000 hours at 85 °C with defined post-test limits (capacitance ±15%, leakage within initial spec) supports predictable long-term performance planning.
• Clear Ripple Current Ratings: Specified ripple current at both 120 Hz and 100 kHz helps designers size cooling and placement to meet application-specific ripple loads.
• Large-Format Mounting Options: Standard three-leg brackets for larger diameters simplify secure mounting; alternative two-leg brackets are available per series guidelines.
• Regulatory Compliance: RoHS compliance supports deployment where restricted-substance conformance is required.
