LAK2G471MELC50ZB

The LAK2G471MELC50ZB is an aluminum electrolytic capacitor in a snap-in terminal (radial can) package, offering 470 µF capacitance at a 400 V rating. It is designed for general-purpose power applications that require high-voltage bulk capacitance and rugged mounting.

Key value points include a 105°C operating range with 2000 hours endurance at 105°C under rated ripple conditions, improved safety features for abnormal voltages, and manufacturing-ready tray packing for mass production.

Key Features

• Capacitance & Rated Voltage — 470 µF nominal capacitance with a 400 V rated voltage suited for high-voltage power circuits.
• High-temperature Endurance — Rated to operate from -25 °C to +105 °C with a specified endurance of 2000 hours at 105 °C under D.C. bias plus rated ripple current.
• Snap-in, Radial Can Package — Snap-in terminal type (φ35 × 50 mm / L: 5 × D: 3.5 cm) provides secure board mounting and straightforward installation in power assemblies.
• Low Loss (tan δ) — Tangent of loss angle (tan δ) specified at 0.20 max (120 Hz, 20 °C), supporting predictable dissipation characteristics.
• Specified Ripple Current — Ripple current ratings of 1.45 A at 120 Hz and 1.667 A at 10 kHz are provided for proper thermal and electrical planning.
• Tolerance & Polarization — ±20% capacitance tolerance and polarized construction for correct circuit integration.
• Safety Design — Improved safety features for abnormally excessive voltage and a pressure relief vent designed to operate without producing dangerous conditions.
• RoHS Compliant — Meets RoHS requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering and bulk energy storage — High-voltage, high-capacitance bulk smoothing in power supplies and converters where 400 V capability is required.
• Equipment exposed to voltage fluctuations — Designed for use in systems operating in environments with fluctuating voltages thanks to enhanced abnormal-voltage safety measures.
• Industrial power electronics — General-purpose use in industrial control and power conversion modules that demand long-term thermal endurance.

Unique Advantages

• Long high-temperature life: 2000 hours endurance at 105 °C supports extended reliability in thermally demanding applications.
• High-voltage capability: 400 V rating enables use in higher-voltage power stages without series stacking.
• Robust mounting: Snap-in radial can simplifies mechanical retention and board-level stability for power assemblies.
• Measured electrical performance: Specified tan δ and ripple current figures allow accurate thermal and electrical design decisions.
• Built-in safety features: Pressure relief vent and improved abnormal-voltage behavior reduce risk of hazardous failure modes.
• Production-ready packaging: Tray packing and mass-production availability support efficient assembly and procurement.
