LLS1H682MELB

The LLS1H682MELB is an aluminum electrolytic capacitor from Nichicon's LLS series featuring a snap-in terminal design and a rated voltage of 50 V with 6800 µF capacitance. It is specified for general-purpose use and is supplied in a radial, can-type snap-in package.

Engineered for sustained operation, this part offers a 3000-hour endurance at 85°C, measurable performance characteristics including specified ripple current and leakage current, and RoHS compliance for environmental compatibility.

Key Features

• High Capacitance: 6.8 mF (6800 µF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C, providing substantial bulk capacitance in a compact can.
• Rated Voltage: 50 V DC rated voltage suitable for medium-voltage applications requiring durable electrolytic capacitance.
• Ripple Current Performance: 3.930 A at 120 Hz (low frequency) and 4.519 A at 50 kHz (high frequency) ripple current ratings to support sustained AC ripple conditions.
• Electrical Loss and Leakage: tanδ (DF) of 0.3 max at 20°C, 120 Hz and a measured leakage current of 1740 µA, enabling predictable dissipation and leakage behavior.
• Endurance and Reliability: Rated for 3000 hours of operation at 85°C under specified conditions; endurance limits for capacitance change, tanδ and leakage conform to series specifications.
• Package and Mounting: Radial, can-type snap-in terminal construction (φ30 × 35L) for secure board installation and tray packing for production handling.
• Temperature Range: Operating temperature range –40°C to +85°C as specified for the LLS series.
• Regulatory Compliance: RoHS compliant, consistent with the RoHS directive cited for the series.

Typical Applications

• General-purpose electronic equipment: Provides bulk capacitance for designs that require a reliable aluminum electrolytic in a snap-in radial package.
• Power supply modules: Rated for 50 V and specified ripple currents, suitable where sustained ripple handling and energy storage are required.
• Industrial power systems: Designed for long endurance at elevated temperature (3000 h at 85°C), supporting continuous operation in industrial environments.

Unique Advantages

• Substantial bulk capacitance: 6800 µF nominal value reduces the number of capacitors needed to achieve required energy storage.
• Durability under thermal stress: Endurance rating of 3000 hours at 85°C provides predictable lifetime performance for sustained high-temperature use.
• Dual-frequency ripple capability: Specified ripple currents at both 120 Hz and 50 kHz clarify performance for low- and high-frequency ripple environments.
• Snap-in radial convenience: Can-type snap-in terminals simplify board mounting and mechanical retention for production assemblies.
• Measured electrical characteristics: Defined tanδ and leakage current values support deterministic design and thermal budgeting.
• RoHS compliant: Meets environmental restriction requirements listed for the series.
