LNR1V684MSE

The LNR1V684MSE is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose applications. It provides a very large capacitance of 680,000 µF (680 mF) at a rated voltage of 35 V, combined with screw-terminal mounting for secure electrical and mechanical connections.

Key performance attributes from the LNR series include an operating temperature range of −40 °C to +85 °C, an endurance rating of 5000 hours at 85 °C, defined leakage-current limits, and substantial ripple-current capability—making it suitable where high bulk capacitance and robust mounting are required.

Key Features

• High Bulk Capacitance: 680,000 µF (680 mF) nominal capacitance with ±20% tolerance at 120 Hz, 20 °C, providing large energy storage per unit for bulk capacitance needs.
• 35 V Rated Voltage: Rated for 35 V DC operation, specified as part of the product's core electrical ratings.
• Temperature and Endurance: Specified operating range −40 °C to +85 °C and endurance of 5000 hours at 85 °C with DC bias plus rated ripple current applied; capacitance change is within ±15% after endurance testing per the LNR series specification.
• Leakage and Dissipation: Specified leakage current 5000 µA; datasheet limit also references the standard leakage-current formula (not more than 3√CV (µA) or 5 mA, whichever is smaller). Tangent of loss angle (tan δ) specified at 0.9.
• High Ripple-Current Capability: Ripple current ratings of 35.2 A at 120 Hz and 40.48 A at 100 kHz support AC ripple handling for DC bus filtering and bulk smoothing applications.
• Robust Screw-Terminal Mechanical Package: Radial can with screw terminals (φ90 body, length 220 mm as supplied); screw-terminal design and standard mounting bracketing on φ51 and larger sizes provide secure electrical and mechanical connections.
• RoHS Compliant: Device is compliant with RoHS requirements as stated in the product data.

Typical Applications

• General-purpose power systems: For designs requiring very high bulk capacitance and screw-terminal connections in general-purpose power electronics.
• Bulk energy storage and smoothing: Where large capacitance and substantial ripple-current handling are required at up to 35 V and elevated temperatures.
• Industrial equipment power supplies: Suitable for systems that need long-duration endurance at elevated ambient temperatures (5000 hours at 85 °C) and reliable screw-terminal mounting.

Unique Advantages

• Exceptional capacitance density: 680,000 µF provides substantial bulk energy storage in a single component, reducing the need for multiple parallel capacitors.
• Designed for high ripple loads: Ripple-current ratings at 120 Hz and 100 kHz allow the capacitor to handle significant AC content on DC rails.
• Long-term endurance: 5000-hour life at 85 °C with defined post-test limits for capacitance, tan δ, and leakage current supports predictable life performance.
• Secure screw-terminal mounting: Screw terminals and radial can package enable robust, low-resistance connections suited to high-current bus installations.
• Clear electrical limits: Specified leakage current and tan δ values allow straightforward verification against system requirements.
• Regulatory compliance: RoHS compliance supports use in assemblies requiring restricted-substance conformity.
