LAK2D471MELA35ZB

The LAK2D471MELA35ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAK series, rated at 470 µF and 200 V. Packaged in a radial can (snap‑in) with compact dimensions of 25 mm × 35 mm, it is designed for general‑purpose power applications requiring bulk capacitance, ripple handling and high‑temperature endurance.

Key value comes from its long‑life specification at elevated temperature, controlled loss and leakage, and safety features for abnormal voltage conditions—making it suitable for industrial and commercial power subsystems operating up to 105°C.

Key Features

• Capacitance & Rated Voltage — 470 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Package & Mounting — Snap‑in terminal, radial can construction with dimensions L: 35 mm × D: 25 mm for secure board mounting and compact footprint.
• Temperature Range & Lifetime — Operates from −25°C to +105°C with endurance specified as 2000 hours at 105°C under rated conditions.
• Ripple Handling — Rated ripple current of 1.3 A at 120 Hz (low frequency) and 1.56 A at 10 kHz (high frequency) to support smoothing and decoupling in power circuits.
• Leakage & Dissipation — Low leakage current listed at 910 µA and a maximum tan δ of 0.20 (120 Hz, 20°C) for predictable loss behavior.
• Safety & Abnormal Voltage Measures — Designed with safety features for abnormally excessive voltage and a pressure relief vent to mitigate hazardous failure modes under fault conditions.
• Regulatory & Packaging — RoHS compliant, supplied in tray packing, and available in mass production quantities.

Typical Applications

• General‑Purpose Power Supplies — Bulk energy storage and ripple suppression for 200 V class DC rails where sustained ripple endurance at elevated temperature is required.
• Industrial Power Modules — Filtering and DC link capacitance in industrial converters and power assemblies operating up to 105°C.
• Commercial Equipment — Energy buffering and smoothing in commercial power electronics that need reliable long‑term performance and safety measures for voltage anomalies.

Unique Advantages

• Long high‑temperature endurance: 2000 hours at 105°C provides predictable life performance in thermally demanding installations.
• Dual‑band ripple capability: Specified ripple ratings at both 120 Hz and 10 kHz cover typical low‑frequency and high‑frequency power environments.
• Safety‑oriented construction: Pressure relief vent and improved measures for abnormal voltage reduce risk in fault conditions.
• Low leakage and controlled loss: 910 µA leakage and tan δ ≤ 0.20 provide stable leakage and dissipation characteristics for design margining.
• Compact, serviceable form factor: Snap‑in radial can (25 × 35 mm) simplifies board mounting for bulk capacitance without excessive board area.
• Production ready: RoHS compliance, tray packing and mass production status support volume manufacturing and procurement.
