LNR1K683MSEB

The LNR1K683MSEB is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications that require very high capacitance at an 80 V rating. Its screw-terminal radial can package and large 68,000 µF capacitance make it suitable where bulk energy storage, smoothing and high ripple handling are needed.

Key value comes from the combination of high capacitance (68 mF), elevated ripple-current capability at both low and high frequencies, long endurance at elevated temperature, and a broad operating temperature range of −40 °C to +85 °C.

Key Features

• High Capacitance: 68,000 µF (68 mF) provides substantial bulk energy storage for smoothing and hold-up applications.
• Rated Voltage: 80 V working voltage suitable for mid-voltage power rails and modules.
• Capacitance Tolerance: ±20% at 120 Hz, 20 °C to set expected capacitance window for design calculations.
• Low-Frequency and High-Frequency Ripple Performance: 15.5 A ripple current at 120 Hz and 17.82 A at 100 kHz to support both mains-frequency and high-frequency switching environments.
• Loss Tangent (tan δ): tanδ = 0.3 (measured at 20 °C, 120 Hz) to characterize dissipation for thermal and ESR considerations.
• Leakage Current: Specified leakage current up to 5,000 µA (5 mA), with datasheet guidance on measurement conditions.
• Endurance: Rated for 5,000 hours at 85 °C under DC bias plus rated ripple; after endurance test, capacitance remains within ±15%, tan δ ≤175% of initial spec, and leakage current ≤ initial specified value.
• Robust Mechanical Package: Radial can with screw terminals and a φ63.5 × 140 mm body (L: 14 × D: 6.35 cm) for secure electrical and mechanical connection in rack- or chassis-mounted power equipment. Standard mounting brackets provided for φ51 and larger diameters.
• Wide Operating Temperature: −40 °C to +85 °C for use across varied ambient conditions.
• Environmental Compliance: RoHS compliant.
• Packaging: Supplied in cardboard packing for standard bulk handling.

Typical Applications

• General-purpose power filtering: Bulk capacitance for smoothing DC rails and reducing ripple where 68,000 µF at 80 V is required.
• Power supply hold-up and energy storage: Provides reservoir capacitance to support transient load demands and short hold-up intervals.
• High-current switching power modules: Suited to systems that impose significant ripple currents at both line frequency and high switching frequencies thanks to specified ripple ratings.

Unique Advantages

• Large stored energy in a single device: 68 mF at 80 V reduces the need for extensive parallel capacitor arrays, simplifying BOM and layout.
• Designed for high ripple environments: Explicit ripple current ratings at 120 Hz and 100 kHz let designers quantify thermal and lifetime performance under real operating conditions.
• Long rated endurance at elevated temperature: 5,000 hours at 85 °C provides predictable aging characteristics and retention limits for long-term planning.
• Secure field connections: Screw terminal radial can and standard mounting brackets enable robust mechanical retention and ease of serviceability.
• Clear electrical characterization: Specified tanδ, leakage current, and tolerance values give engineers the measurable parameters needed for thermal, ESR, and reliability analyses.
• RoHS compliant: Meets environmental regulation requirements for lead-free assemblies.
