LAKW6101MELZ40ZB

The LAKW6101MELZ40ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAK series designed for high‑voltage DC applications. It provides a 100 µF capacitance at a 420 V rating with snap‑in radial can packaging for secure board mounting.

Engineered for environments with voltage fluctuation, this capacitor supports continuous operation up to 105°C, with endurance tested at rated ripple current for 2000 hours, and includes safety features to handle abnormally excessive voltage. It is RoHS compliant for modern production requirements.

Key Features

• High voltage rating (420 V): Rated for 420 V DC operation, supporting high‑voltage DC rail and power conversion circuits.
• Capacitance (100 µF): Provides bulk energy storage and smoothing for power supplies and DC link applications.
• 105°C endurance: Specified operating temperature up to 105°C with endurance validated by 2000 hours application of rated ripple current at 105°C.
• Snap‑in radial can package: Snap‑in terminals for robust board retention and straightforward insertion in power assemblies.
• Ripple current capability: Rated ripple: 690 mA at 120 Hz and 793.5 mA at 10 kHz, enabling reliable ripple handling across typical power frequencies.
• Leakage current specification: Leakage current meets I ≤ 3√(C·V) µA after 5 minutes at 20°C (C: µF, V: V), enabling predictable standby behavior.
• Tangent of loss angle (tan δ): tan δ ≤ 0.20 at 120 Hz, 20°C, for predictable loss characteristics in AC‑biased applications.
• Safety features: Pressure relief vent and improved protection against abnormally excessive voltage to prevent dangerous failure modes under abnormal conditions.
• RoHS compliance: Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized design: Polar capacitor intended for DC applications where polarity is observed.
• Physical dimensions: Body dimensions approximately L: 4 × D: 2.2 cm for board layout and mechanical planning.

Typical Applications

• Industrial power supplies: Bulk smoothing and DC link filtering on high‑voltage rails where voltage fluctuation and elevated temperatures are present.
• Power conversion equipment: Energy storage and ripple suppression in rectifier circuits and inverter DC links that require high voltage capability.
• Voltage‑fluctuation prone systems: Use in equipment deployed in environments with unstable mains to leverage the capacitor’s abnormal‑voltage safety features and high‑temperature endurance.
• General purpose high‑voltage filtering: General purpose filtering in systems that require a polarized, snap‑in high‑voltage capacitor rated for elevated temperatures.

Unique Advantages

• Validated high‑temperature endurance: 2000 hours at 105°C under rated ripple current—provides predictable aging and performance for demanding thermal environments.
• High voltage range support: 420 V rating (part of an extended voltage range including 200 V and 400 V in the series) for flexibility in high‑voltage designs.
• Robust ripple handling: Specified ripple current at both low and high frequencies (690 mA at 120 Hz, 793.5 mA at 10 kHz) to suit a range of power‑electronic operating conditions.
• Safety‑focused construction: Pressure relief vent and tested measures against abnormally excessive voltage reduce the risk of hazardous failures under abnormal stress.
• Predictable electrical behavior: Leakage current bounded by I ≤ 3√(C·V) µA and tan δ ≤ 0.20 at 120 Hz help ensure consistent performance in system designs.
• RoHS compliance: Meets regulatory requirements for restricted substances in commercial products.
