LAK2D471MELB25ZB

The LAK2D471MELB25ZB is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 470 µF capacitance at a 200 V rating in a compact φ30 × 25 mm can with a snap‑in mounting for secure board retention.

Engineered for reliability under ripple and elevated temperature, this part offers a 2000‑hour endurance at 105°C with built‑in safety features for use in equipment exposed to voltage fluctuation. RoHS compliant and supplied in tray packing for production handling.

Key Features

• Capacitance and Tolerance: 470 µF nominal with ±20% tolerance (at 120 Hz, 20°C), suitable for bulk energy storage and smoothing applications within its rated tolerance.
• Rated Voltage: 200 V DC rating for medium‑voltage power rails and converter circuits.
• Temperature Performance: Operating temperature range of −25°C to +105°C with endurance specified as 2000 hours at 105°C under rated ripple current.
• Ripple Current Capability: 1.35 A at 120 Hz and 1.62 A at high frequency (specification entry), supporting sustained AC ripple stress.
• Leakage and Dissipation: Typical leakage current listed as 910 µA; datasheet leakage-characteristic formula I ≤ 3√(C·V) µA (after 5 minutes at 20°C). Tangent of loss angle (tan δ) max 0.20 at 120 Hz, 20°C.
• Mounting and Package: Snap‑in radial can (φ30 × 25 mm) for secure mechanical retention and easy insertion into power assemblies; packaged in trays for production handling.
• Safety Features: Pressure relief vent design and series safety performance to mitigate abnormal overvoltage conditions as specified in the datasheet.
• Compliance: RoHS compliant.

Typical Applications

• Industrial Power Equipment: Suited for general‑purpose power modules and industrial electronics that require stable capacitance on medium‑voltage rails.
• Equipment in Voltage‑Fluctuating Areas: Designed for systems exposed to fluctuating supply voltages, leveraging the series’ enhanced safety features and endurance under ripple.
• Power Conversion and Filtering: Used where bulk storage, smoothing, and ripple handling are required at up to 200 V.
• Commercial and Utility Electronics: Appropriate for non‑automotive equipment requiring a robust 200 V electrolytic solution with snap‑in mounting.

Unique Advantages

• High‑Voltage Capability: 200 V rating enables use on medium‑voltage rails without series stacking.
• Long Endurance at Elevated Temperature: 2000 hours at 105°C under rated ripple current supports extended service life in hot operating environments.
• Robust Ripple Handling: Rated ripple currents of 1.35 A (120 Hz) and 1.62 A (high frequency) help manage AC stress in power supply and converter circuits.
• Safety‑Oriented Design: Pressure relief vent and series safety specifications reduce risk during abnormal overvoltage conditions.
• Production‑Friendly Packaging: Tray packing supports automated handling and board‑level assembly workflows.
• Clear Electrical Limits: Specified leakage current behavior and tan δ limit (0.20 max at 120 Hz) provide predictable performance characteristics for design validation.
