LLS2D821MELB

The LLS2D821MELB is an aluminum electrolytic, snap-in terminal capacitor in Nichicon’s LLS series designed for general-purpose power applications. It combines high capacitance (820 µF) with a 200 V rating and a radial snap-in can package to deliver reliable bulk energy storage in a compact footprint.

Engineered for continuous operation up to 85°C, the LLS2D821MELB provides long-term ripple-current endurance and RoHS compliance, making it suitable for industrial and power-electronics designs that require stable filtering and energy buffering.

Key Features

• Capacitance & Voltage – 820 µF rated capacitance at 200 V with tolerance of ±20% (–20% to 20%).
• Snap-In Can Package – Radial, snap-in terminal type for secure PCB mounting; package dimensions L: 3 × D: 3 cm and seated height max 1.181 inch.
• High Ripple-Current Capability – Rated ripple current of 2.8 A at 120 Hz and 4.2 A at 50 kHz to handle continuous AC ripple stresses.
• Operating Temperature & Endurance – Specified for –40°C to 85°C operation with endurance of 3000 hours at 85°C under rated ripple current conditions.
• Electrical Characteristics – Polarized design; leakage current specified as I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ (loss tangent) max 0.15 at the 200 V rating per LLS series data.
• Regulatory Compliance – RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies – Bulk smoothing and input filtering where 820 µF at 200 V and high ripple capability support stable DC rails.
• Inverters and Motor Drives – DC-link smoothing and energy buffering applications that benefit from snap-in mechanical retention and long endurance at elevated temperature.
• Power Conversion Modules – General-purpose filtering and energy storage in power converters and power-electronics assemblies requiring RoHS compliance.

Unique Advantages

• Long-term endurance: 3000 hours at 85°C under rated ripple current provides predictable lifetime performance in continuous-use environments.
• High ripple handling: Specified ripple currents (2.8 A at 120 Hz, 4.2 A at 50 kHz) reduce thermal buildup and support demanding AC ripple conditions.
• Secure snap-in mounting: Radial snap-in can design simplifies PCB retention and mechanical stability for power assemblies.
• Compact, high-energy density: 820 µF at 200 V in a 3 × 3 cm can delivers substantial energy storage in a compact footprint.
• Predictable electrical limits: Defined leakage current and tan δ values enable conservative design margins and easier validation.
• Environmental compliance: RoHS conformity supports regulatory and sustainability requirements.
