LNR2A683MSE

The LNR2A683MSE is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNR series, rated 100 V with 68 mF (68,000 µF) capacitance. It is a polarized, radial can package designed for general-purpose power applications that require large capacitance and secure screw-terminal mounting.

Key value comes from its high capacitance at elevated voltage, defined endurance (5,000 hours at 85 °C), and measured ripple performance at both low and high frequencies—delivering predictable electrical behavior for system design and procurement.

Key Features

• Capacitance & Voltage: 68 mF (68,000 µF) rated at 100 V, providing substantial stored charge in a single component.
• Screw-terminal mounting: Radial can with screw terminals for robust electrical and mechanical connection; nominal bolt size M5 for φ76.2 body diameters (3-leg bracket furnished as standard).
• Endurance: Rated lifetime of 5,000 hours at 85 °C under DC bias plus rated ripple current, with defined limits for capacitance change, tan δ, and leakage current after endurance testing.
• Operating temperature: Specified from –40 °C to +85 °C for 10 to 100 V versions, enabling use across a wide ambient range.
• Loss and leakage: Tangent of loss angle tan δ specified at 0.3 (measurement at 120 Hz, 20 °C) and a leakage current value of 5,000 µA (5 mA) as characterized for this part.
• Ripple current performance: 18.2 A at 120 Hz and 20.93 A at 100 kHz, providing defined ripple-handling capability at both low and high frequencies.
• Tolerance & polarization: Capacitance tolerance ±20% at 120 Hz, polarized device—observe polarity in application.
• Form factor and packing: Body dimensions φ76.2 × 140 mm (L: 14 cm × D: 7.62 cm), supplied with cardboard packing and in mass-production status; RoHS compliant.

Typical Applications

• General-purpose power systems: Suitable where high bulk capacitance and secure screw-terminal connections are needed for power assemblies.
• Power filtering and smoothing: Large capacitance and defined ripple-current ratings support filtering/use in DC link and smoothing stages.
• Industrial equipment: Robust mechanical mounting and broad operating-temperature range make it applicable in industrial power modules and control cabinets requiring polarized bulk capacitors.

Unique Advantages

• High single-component capacitance: 68 mF at 100 V reduces the number of parallel parts required for large energy storage or bulk filtering.
• Defined ripple capability: Specified ripple currents at 120 Hz and 100 kHz enable predictable thermal and electrical design for both mains-frequency and high-frequency applications.
• Long-term endurance data: 5,000 hours at 85 °C with post-test limits on capacitance change, tan δ, and leakage current provides quantifiable lifecycle expectations.
• Screw-terminal robustness: Screw terminals and standard 3-leg bracket for φ76.2 bodies offer secure mounting and reliable electrical connection in heavy-current applications.
• Clear electrochemical characteristics: Specified tan δ (0.3) and leakage current (5,000 µA) provide measurable parameters for thermal and leakage budgeting in designs.
• RoHS compliant: Environmentally compliant manufacturing and materials status for regulatory considerations.
