LAKW6151MELC25

The LAKW6151MELC25 is a snap-in terminal aluminum electrolytic capacitor designed for high-voltage, high-temperature applications. As a polarized, radial can snap-in type rated up to 420 V and specified for operation from -25°C to +105°C, it addresses demanding power and industrial environments where robust ripple handling and long-term endurance are required.

Key Features

• High Voltage Range — Rated voltage up to 420 V with extended availability at 200 V and 400 V, supporting a variety of high-voltage power designs.
• Capacitance and Tolerance — 150 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C), suitable for bulk energy storage and filtering.
• Thermal Endurance — Designed for 2000 hours of rated ripple current application at 105°C, enabling reliable operation in elevated-temperature systems.
• Leakage and Loss Characteristics — Leakage current I ≤ 3√(C·V) μA after 5 minutes at 20°C and tan δ ≤ 0.20 (120 Hz, 20°C), supporting predictable leakage and dissipation behavior.
• Ripple Current Performance — Rated ripple current of 820 mA at 120 Hz and 943 mA at 10 kHz, providing effective smoothing and ripple handling across low- and higher-frequency applications.
• Safety Features — Improved safety design with a pressure relief vent that operates under abnormal conditions to reduce risk of hazardous failures.
• Package and Mounting — Snap-in radial can (φ35 × 25 mm) for secure PCB mounting and robust mechanical retention in compact power assemblies.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), meeting contemporary environmental requirements.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy storage in high-voltage AC/DC and DC/DC converters operating in industrial temperature ranges.
• UPS and Backup Systems — Energy buffering and ripple suppression where high voltage rating and long endurance at 105°C are required.
• Motor Drives and Inverters — DC link and filtering duties in systems that demand robust ripple current capability and thermal reliability.
• Voltage-Fluctuating Environments — Systems exposed to variable input voltages benefit from the capacitor’s extended voltage range and improved safety features for abnormal voltages.

Unique Advantages

• Extended High-Temperature Life: 2000-hour endurance at 105°C under rated ripple current reduces the need for frequent replacements in hot operating environments.
• High-Voltage Flexibility: Availability across 200 V, 400 V and 420 V ratings enables designers to standardize on a single series for multiple voltage rails.
• Predictable Electrical Behavior: Specified leakage current formula and tan δ limit ensure designers can model leakage and dissipation precisely in power calculations.
• Robust Ripple Handling: Defined ripple current values at 120 Hz and 10 kHz support effective filtering across common power frequencies and higher-frequency switching noise.
• Built-In Safety Design: Pressure relief vent and improved abnormal-voltage features reduce the likelihood of hazardous failures under stress conditions.
• RoHS Compliance: Conforms to current RoHS directives, simplifying regulatory compliance for target products.
