LNR2D682MSEN

The LNR2D682MSEN from Nichicon is a screw-terminal, radial-can aluminum electrolytic capacitor offering 6800 µF capacitance at a 200 V rated voltage. It is a polarized, general-purpose power capacitor designed for applications that require high bulk capacitance and robust ripple-handling in a through-hole screw-terminal package.

Key value propositions include high capacitance for energy storage, substantial low- and high-frequency ripple current capability, and a long 5,000-hour endurance rating at 85°C, all supplied in a φ51 × 140 mm package with secure screw terminals.

Key Features

• Capacitance & Tolerance — 6.8 mF (6800 µF) nominal capacitance with a tolerance of −20% to +20%, suitable for bulk energy storage and smoothing tasks.
• 200 V Rated Voltage — Designed for higher-voltage DC systems that require a stable 200 V rating.
• High Ripple Current Capability — Low-frequency ripple current of 7.3 A (120 Hz) and high-frequency ripple current of 8.76 A (100 kHz) to handle AC ripple and switching noise.
• Electrical Loss and Leakage — Specified tanδ (DF) of 0.15 (measured at 20°C, 120 Hz) and a measured leakage current of 3490 µA for predictable performance under load.
• Screw Terminal, Radial Can Package — Robust screw-terminal mounting and radial can construction for secure electrical and mechanical connections in power assemblies.
• Temperature & Endurance — Rated for operation from −25°C to +85°C with a life/endurance rating of 5000 hours at 85°C.
• Physical Size & Packaging — Compact footprint for its capacitance: φ51 × 140 mm (L: 14 × D: 5.1 cm), supplied in cardboard packing; mass-production status ensures availability.
• Regulatory — RoHS compliant.

Typical Applications

• Power supply filtering — Bulk energy storage and smoothing in higher-voltage DC power supplies, leveraging 6800 µF capacitance and high ripple current ratings.
• DC link and energy buffering — Energy buffering in converter/inverter and power conditioning circuits where 200 V rating and robust ripple capability are required.
• Industrial power electronics — Use in general-purpose industrial power systems that demand durable screw-terminal connections and long-term endurance at elevated temperature.

Unique Advantages

• Large bulk capacitance: 6.8 mF provides substantial energy storage for smoothing and buffering in power circuits, reducing the need for multiple smaller capacitors.
• High ripple-handling: Specified ripple currents at both 120 Hz and 100 kHz (7.3 A and 8.76 A) allow the capacitor to address low- and high-frequency ripple from switching systems.
• Secure screw-terminal mounting: Screw terminals and radial can construction enable reliable, low-resistance connections for high-current paths.
• Endurance-rated: 5000 hours at 85°C endurance rating supports long-term operation in elevated-temperature environments when used within specified conditions.
• Measurable electrical characteristics: Published tanδ (0.15 at 20°C, 120 Hz) and specified leakage current (3490 µA) allow predictable design margins and validation in prototypes.
• Regulatory compliance and production readiness: RoHS compliant and listed as mass production, simplifying procurement and lead-time planning.
