LNR1V684MSEN

The LNR1V684MSEN is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose applications. It provides 680,000 µF of capacitance at a 35 V rating in a φ90×220L package with screw terminals for secure, high-current connections.

Engineered for robust operation, this capacitor is specified for -40°C to +85°C operation, a 5000-hour endurance at 85°C under rated ripple and DC bias, and is RoHS compliant—making it suitable where large bulk capacitance and reliable long-term performance are required.

Key Features

• Very large capacitance: 680,000 µF (680 mF) bulk capacitance for energy storage and smoothing in power systems.
• Rated voltage and tolerance: 35 V rated voltage with ±20% capacitance tolerance (measured at 120 Hz, 20°C).
• Screw terminal construction: Radial can with screw terminals for secure mechanical mounting and high-current connections; body diameter φ90 with 220 mm length.
• Operating temperature and lifetime: Specified for -40°C to +85°C operation and endurance of 5000 hours at 85°C under rated ripple and DC bias; post‑test capacitance change is within ±15% per series endurance criteria.
• Loss characteristic: Tangent of loss angle (tan δ) specified at 0.9 for this part.
• Ripple current capability: 35.2 A at 120 Hz and 40.48 A at 100 kHz, supporting substantial AC ripple handling in power applications.
• Polarized, radial can package: Polarized electrolytic design in a radial can with screw terminals and standard bracket options for φ51 and larger sizes per series configuration.
• Compliance: RoHS compliant material and manufacturing status.

Typical Applications

• General-purpose power filtering: Large bulk capacitance and high ripple current ratings make it suitable for smoothing and reservoir tasks in DC power systems.
• Power supply bulk storage: Used where substantial energy storage is required at moderate voltage (35 V) to support transient loads or hold-up times.
• High-current DC applications: Screw-terminal connections and high ripple specs support secure, low-impedance connections in high-current environments.

Unique Advantages

• Massive bulk capacitance: 680,000 µF provides significant energy storage in a single component, reducing the number of parallel capacitors required.
• Secure screw-terminal interface: Mechanical screw terminals enable robust electrical and mechanical connection for high-current systems.
• Designed for long-term operation: 5000-hour endurance at 85°C with defined post-test limits on capacitance, tan δ, and leakage current supports predictable lifecycle performance.
• High ripple tolerance: Specified ripple currents at both low and high frequencies (120 Hz and 100 kHz) accommodate a range of switching and line-frequency environments.
• Broad operating range: Rated for -40°C to +85°C, covering typical industrial ambient conditions for general-purpose designs.
• Regulatory compliance: RoHS status provides assurance for environmental and material-signature requirements.
