LNR1A334MSEN

The LNR1A334MSEN is an aluminum electrolytic capacitor in Nichicon's LNR series, configured as a screw-terminal, radial can for robust electrical and mechanical connections. It provides a nominal capacitance of 330000 µF (330 mF) at a rated voltage of 10 V and is intended for general-purpose applications that require high bulk capacitance in a screw-terminal package.

Key value propositions include high-capacitance energy storage, a wide operating temperature range of −40 °C to 85 °C, and a 5000-hour endurance rating at 85 °C under rated conditions.

Key Features

• High Capacitance — 330000 µF (330 mF) nominal capacitance for substantial bulk energy storage and smoothing at low voltage systems.
• Rated Voltage — 10 V rated voltage appropriate for low-voltage power rails and bulk storage applications.
• Screw Terminal Mounting — Radial can with screw terminals (φ63.5 body diameter) for secure electrical and mechanical connections; nominal bolt diameter for φ63.5 is M5 per series dimensions.
• Endurance — 5000 hours at 85 °C with DC bias plus rated ripple current; after endurance test, capacitance remains within ±15% of initial value and leakage current remains within initial specified limits.
• Leakage Current — Specified leakage current of 5000 µA (5 mA) and in-series datasheet guidance: after 5 minutes’ application of rated voltage leakage not more than 3√(C·V) µA or 5 mA, whichever is smaller.
• Ripple Current Capability — Rated ripple current of 15.9 A at 120 Hz and 18.29 A at 100 kHz to support substantial AC ripple on DC bus applications.
• Operating Temperature Range — −40 °C to 85 °C, supporting a broad range of ambient conditions for general-purpose use.
• Tolerance and Polarization — Capacitance tolerance ±20% (at 120 Hz, 20 °C); polarized device suitable for correct polarity installation.
• Compliance and Packaging — RoHS compliant and supplied in cardboard packing; part is in mass production.

Typical Applications

• General-purpose bulk energy storage — Where high capacitance at low voltage is required for hold-up, smoothing, or buffering in power assemblies; the screw-terminal package facilitates secure connections.
• High-ripple DC bus support — Suitable for designs requiring significant ripple current handling (15.9 A at 120 Hz, 18.29 A at 100 kHz) within the specified temperature and endurance limits.
• Panel or chassis-mounted power assemblies — Screw-terminal format and radial can packaging provide a mechanically robust solution for assemblies that require bolted electrical connections.

Unique Advantages

• Massive capacitance in a compact form — 330000 µF at 10 V provides large energy storage density for low-voltage systems, reducing the number of parallel components required.
• Secure screw-terminal connection — Screw terminals and M5 nominal bolt accommodation (for φ63.5 body) enable reliable, low-resistance terminations for high-current paths.
• Proven endurance specification — 5000-hour life at 85 °C under rated stress delivers measurable reliability data for long-term design planning.
• Designed for high ripple environments — Explicit ripple current ratings at 120 Hz and 100 kHz allow designers to match the capacitor to their AC ripple conditions with confidence.
• Wide ambient range and RoHS compliance — −40 °C to 85 °C operating range and RoHS compliance support environmentally regulated designs across diverse ambient conditions.
