LAK2D470MELZ20

The LAK2D470MELZ20 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAK series, specified for general-purpose power applications. It features a 47 µF capacitance at 200 V in a compact 22 mm × 20 mm radial, can-style snap-in package.

Designed for equipment operating in areas with voltage fluctuation, this capacitor offers extended ripple endurance and safety-focused construction, making it suitable where sustained ripple current, elevated temperature endurance and reliable pressure-relief behavior are required.

Key Features

• Snap-in Radial Can Package Compact 22 × 20 mm snap-in can for robust board mounting and simplified assembly in power systems.
• Electrical Characteristics 47 µF nominal capacitance with ±20% tolerance and 200 V rated voltage for general-purpose power applications.
• High Temperature Endurance Rated for operation from −25°C to +105°C with endurance verified by 2000 hours application of rated ripple current at 105°C.
• Ripple Current Performance Specified ripple current of 350 mA at 120 Hz and 420 mA at 10 kHz, enabling stable filtering and smoothing under sustained AC stress.
• Low Dissipation Factor tan δ ≤ 0.20 (120 Hz, 20°C) to limit losses in AC-biased applications.
• Enhanced Safety Design Pressure relief vent designed to operate without producing flames, ignition or dispersion of case fragments under abnormal overvoltage conditions.
• RoHS Compliance Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for reduced hazardous substance content.

Typical Applications

• Power Supplies and Converters — Bulk filtering and smoothing in power supply rails where steady ripple endurance and 200 V rating are required.
• Industrial Equipment — Suitable for general-purpose industrial electronics and machinery operating in environments with voltage fluctuations.
• Stationary Power Systems and UPS — Energy smoothing and ripple handling in backup power and stationary systems that demand reliable high-temperature performance.
• General-Purpose Electronic Equipment — Use where compact, high-voltage-capable electrolytic capacitors with proven endurance are needed.

Unique Advantages

• Proven High-Temperature Endurance: 2000-hour rated ripple current endurance at 105°C provides predictable lifetime behavior under sustained thermal and electrical stress.
• Measurable Ripple Capability: Explicit ripple current ratings (350 mA at 120 Hz; 420 mA at 10 kHz) allow designers to size capacitors to real application ripple loads.
• Compact Snap-In Form Factor: 22 × 20 mm radial snap-in can reduces board space while providing secure mechanical mounting for power assemblies.
• Safety-Focused Construction: Pressure relief vent operation minimizes risk of hazardous failure modes during abnormal overvoltage events.
• Regulatory Compliance: RoHS conformity supports environmentally conscious designs and regulatory requirements.
• Stable Loss Characteristics: Low dissipation factor (tan δ ≤ 0.20) reduces internal heating and improves efficiency in AC-biased circuits.
