LLS2C821MELB

The LLS2C821MELB is an aluminum electrolytic, snap-in terminal capacitor designed for general-purpose power applications. It provides 820 µF capacitance at a 160 V rating in a compact φ30 × 25 mm can with a snap-in mounting style.

Engineered for robust ripple handling and long-term operation, this part delivers defined ripple current capability, controlled dissipation factor, low leakage current, a –40 °C to 85 °C operating range, and a 3000‑hour endurance at 85 °C for demanding board-level power designs.

Key Features

• Electrical Performance — 820 µF nominal capacitance with ±20% tolerance and a rated voltage of 160 V, suitable for circuits that require high capacitance at elevated DC voltage.
• Ripple Current Capability — 2.64 A at 120 Hz (low frequency) and 3.96 A at 50 kHz (high frequency) to support continuous AC ripple in power conditioning and DC link applications.
• Loss and Leakage Characteristics — tanδ specified at 0.15 (max) at 20 °C / 120 Hz for the 160 V rating, and measured leakage current of 1080 µA; datasheet leakage current formula: I ≤ 3√CV (μA) after 5 minutes at 20 °C.
• Reliability and Lifetime — Endurance rating of 3000 hours at 85 °C when subjected to rated ripple and DC bias, with defined limits on capacitance change, tanδ, and leakage current after the test.
• Operating Environment — Specified operating temperature range of –40 °C to +85 °C for wide ambient compatibility.
• Package and Mounting — Radial, can-style snap-in package (φ30 × 25 mm) supplied in tray packing for straightforward PCB assembly using snap-in terminals.
• Compliance — RoHS‑compliant construction.

Typical Applications

• General-purpose power circuits — Use where 820 µF at 160 V capacitance is needed for bulk energy storage, smoothing, or decoupling in board-level power designs.
• Power conditioning modules — Snap-in mounting and specified ripple current ratings support integration into assemblies with continuous AC ripple and DC bias.
• Industrial power electronics — Electrical and thermal specifications (–40 °C to 85 °C, 3000 h at 85 °C) make the device suitable for long-life power subsystems in industrial equipment.

Unique Advantages

• High-voltage capacitance in a compact can — 820 µF at 160 V in a φ30 × 25 mm package provides substantial energy density for space-constrained PCBs.
• Defined ripple endurance — Rated ripple currents of 2.64 A (120 Hz) and 3.96 A (50 kHz) enable designers to size capacitors against real ripple loading conditions.
• Long-term stability — 3000-hour endurance at 85 °C under rated conditions supports predictable lifetime behavior in thermal stress environments.
• Controlled dissipation factor — tanδ specified at 0.15 (max) at 20 °C / 120 Hz for consistent AC loss characteristics at the 160 V rating.
• Low leakage behavior — Measured leakage current of 1080 µA and the datasheet leakage formula provide clear limits for leakage budgeting in power designs.
• RoHS compliance — Meets RoHS directive requirements for restricted substances.
