LAK2G560MELA20ZB

The LAK2G560MELA20ZB is a Nichicon LAK series aluminum electrolytic capacitor in a snap‑in terminal (radial can) package. It is rated 56 µF at 400 V with ±20% tolerance and designed for general‑purpose applications that require high voltage capability and robust thermal endurance.

Engineered for equipment operating in voltage‑fluctuating environments, this part combines elevated temperature performance (–25°C to 105°C) with series safety features and tray packing for mass production assembly.

Key Features

• Capacitance & Voltage — 56 µF nominal capacitance rated at 400 V DC with ±20% tolerance (specified at 120 Hz, 20°C).
• High‑temperature Endurance — Designed to withstand rated ripple current for 2000 hours at 105°C, supporting reliable operation in elevated ambient conditions.
• Safety and Abnormal Voltage Handling — LAK series includes improved safety features for abnormally excessive voltage and a pressure relief vent that operates without dangerous conditions.
• Ripple Current Performance — Specified ripple current: 380 mA at 120 Hz and 437 mA at 10 kHz, enabling effective smoothing and filtering under AC ripple stress.
• Leakage & Loss Characteristics — Leakage current defined by I ≤ 3√(C·V) μA after 5 minutes at 20°C; tangent of loss angle (tan δ) 0.20 max at 120 Hz, 20°C.
• Package & Mounting — Snap‑in radial can, footprint sized φ25 × 20 mm (D: 2.5 cm, L: 2 cm), supplied in tray packing suitable for volume production.
• Environmental Compliance — RoHS compliant per the directive cited in the series datasheet.

Typical Applications

• General‑purpose power electronics — Bulk capacitance and ripple suppression in equipment where a 400 V rating and robust thermal life are required.
• Equipment subject to supply fluctuations — Suited for systems operating in voltage‑fluctuating areas due to series safety features and abnormal‑voltage handling.
• Panel and assembly integration — Snap‑in radial can format simplifies mechanical mounting and board retention in production environments.

Unique Advantages

• Long high‑temperature life: 2000 hours at 105°C under rated ripple current reduces maintenance and replacement frequency in hot environments.
• High‑voltage capability: 400 V rating supports higher DC bus applications without needing larger form‑factor parts.
• Predictable leakage behavior: Leakage current specified by a clear formula (I ≤ 3√CV), aiding margin calculations during design and qualification.
• Manufacturing friendly: Snap‑in terminals and tray packing support efficient assembly and handling in mass production workflows.
• Safety‑oriented design: Pressure relief vent and series‑level abnormal voltage measures provide controlled response under stress conditions.
• Regulatory compliance: RoHS compliance simplifies regulatory review for end products.
