LAK2D821MELC35

The LAK2D821MELC35 is an aluminum electrolytic, snap‑in terminal capacitor rated at 820 µF and 200 V, sized φ35 × 35 mm. It is designed for general‑purpose power applications that require high capacitance in a robust, snap‑in can package.

Built for demanding thermal and ripple environments, this part delivers long endurance at elevated temperature and is suitable for equipment exposed to voltage fluctuations where reliable bulk energy storage and smoothing are needed.

Key Features

• Capacitance & Rated Voltage — 820 µF nominal capacitance at 200 V rating, with a capacitance tolerance of ±20% (120 Hz, 20°C).
• Snap‑in Can Package — Radial, can-style snap‑in mounting for secure board retention and high-current PCB installations; package size φ35 × 35 mm.
• High‑Temperature Endurance — Designed to withstand 2000 hours at 105°C when subjected to DC bias plus rated ripple current, supporting long service life in hot environments.
• Ripple Current Capability — Rated ripple current: 1.99 A at 120 Hz and 2.388 A at 10 kHz, enabling effective filtering and smoothing under high AC ripple conditions.
• Leakage and Loss Characteristics — Measured leakage current 1.21 mA and tangent of loss angle (tan δ) up to 0.20 max at 120 Hz, 20°C for predictable dissipation behavior.
• Safety Features — Series design includes improved safety measures for abnormally excessive voltage and a pressure relief vent to reduce hazardous failure modes.
• Compliance & Packaging — RoHS compliant and supplied in tray packing; part is in mass production.

Typical Applications

• Power Supplies — Bulk energy storage and output smoothing for linear and switching power supplies operating up to 200 V.
• Industrial Equipment — Filtering and energy buffering in industrial systems where elevated temperatures and voltage fluctuations are present.
• Energy Conversion & Inverters — DC link smoothing and ripple handling in converter and inverter modules that require robust ripple current capability.
• UPS and Backup Systems — Bulk capacitance for hold‑up and transient support in uninterruptible power supplies and standby power units.

Unique Advantages

• High Capacitance in a Compact Snap‑in Can: 820 µF at 200 V delivers substantial energy density in a φ35 × 35 mm form factor for space‑constrained power designs.
• Designed for Elevated Temperatures: 2000‑hour endurance at 105°C under rated ripple current reduces maintenance and replacement in hot installations.
• Strong Ripple Handling: 1.99 A (120 Hz) and 2.388 A (10 kHz) ripple ratings support demanding AC ripple environments and improve DC bus stability.
• Predictable Leakage and Dissipation: Specified leakage current (1.21 mA) and tan δ (≤0.20) help designers budget standby losses and thermal dissipation accurately.
• Safety‑Focused Series Design: Pressure relief vent and series‑level protections mitigate risk from abnormal overvoltage events.
• Production‑Ready Supply: RoHS compliant and available in tray packing with mass production status for reliable procurement and assembly.
