LAK2D471MELZ40ZB

The LAK2D471MELZ40ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAK series, specified for high-voltage, general-purpose power applications. It combines a 470 µF capacitance with a 200 V rated voltage in a φ22 × 40 mm can for snap‑in mounting.

Designed for endurance in demanding environments, this capacitor is built to withstand rated ripple current for 2000 hours at 105°C and includes safety features to tolerate abnormal voltage conditions—making it suitable for equipment operating where supply voltage can fluctuate.

Key Features

• Electrical Performance — 470 µF capacitance at a 200 V rating with ±20% tolerance; tangent of loss angle (tan δ) specified to 0.20 max at 120 Hz, 20°C.
• High Ripple Handling — Rated ripple current of 1.3 A at 120 Hz and 1.56 A at 10 kHz to support filtering and smoothing in power circuits.
• Low Leakage — Low leakage behavior with the unit specified at 0.91 mA, supporting stable DC performance after application of rated voltage.
• Thermal Endurance — Specified for operation from -25°C to +105°C and guaranteed to withstand rated ripple current for 2000 hours at 105°C.
• Safety and Abnormal‑Voltage Tolerance — LAK series design includes improved safety features and a pressure relief vent intended to operate under abnormal conditions without hazardous failure modes.
• Mechanicals & Mounting — Snap‑in terminal, radial can package (φ22 × 40 mm) suitable for through‑hole snap‑in installations; supplied in tray packing for mass production handling.
• Compliance — RoHS‑compliant per provided product information.

Typical Applications

• Power Supply Filtering — Bulk and smoothing capacitor for high‑voltage DC rails where stable capacitance and ripple handling are required.
• Industrial Power Equipment — Use in equipment exposed to supply fluctuations, leveraging the part’s endurance at 105°C and abnormal‑voltage safety features.
• General‑Purpose Electronic Systems — Suitable for a wide range of general‑purpose power and control circuits needing a high‑voltage electrolytic capacitor with snap‑in mounting.

Unique Advantages

• Long‑life High‑temperature Endurance: 2000 hours at 105°C under rated ripple current provides predictable lifetime performance in thermally demanding designs.
• Robust Ripple Capability: Dual ripple ratings (1.3 A at 120 Hz and 1.56 A at 10 kHz) enable effective filtering across different switching and line frequency conditions.
• Abnormal‑Voltage Safety Features: Series‑level design improvements and a pressure relief vent reduce the risk of dangerous failure modes under excessive voltage conditions.
• Snap‑In Mechanical Convenience: Radial, snap‑in can simplifies PCB mounting for through‑hole assemblies and supports automated tray handling for production.
• Low Leakage Characteristic: Measured leakage of 0.91 mA after voltage application helps maintain DC stability in power rails.
• Regulatory Compliance: RoHS compliance supports use in regulated electronic products and simplifies environmental compliance efforts.
