LAK2D101MELZ20ZB

The LAK2D101MELZ20ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAK series. It delivers 100 µF capacitance at a 200 V rating in a compact 22 × 20 mm radial can optimized for general-purpose power applications.

Engineered for environments with voltage fluctuation, this part offers extended high-voltage options, improved safety features for abnormal over-voltage conditions and proven endurance under elevated temperature and ripple stress, while complying with RoHS (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Voltage: 100 µF rated at 200 V — suitable for medium-voltage DC filtering and bulk energy storage in compact assemblies.
• High-temperature endurance: Specified to withstand 2000 hours of rated ripple current at 105°C with defined limits for capacitance change, tan δ and leakage current after the endurance test.
• Ripple current capability: 500 mA at 120 Hz and 600 mA at 10 kHz — supports sustained AC ripple conditions common in power supply applications.
• Leakage current specification: I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20°C, providing predictable leakage behavior for design margining.
• Safety features: Improved safety for abnormally excessive voltage with a pressure-relief vent design that operates without flame or dispersion of case fragments; qualified for limited DC current tests relevant to abnormal-voltage conditions for 200 V, C < 330 µF with specified test voltages.
• Package & mounting: Radial can, snap-in terminal package sized 22 × 20 mm (φD × L) for secure board mounting and compact power assemblies.
• Temperature range & tolerance: Operating range −25°C to +105°C with capacitance tolerance ±20% (at 120 Hz, 20°C).
• RoHS compliant: Meets RoHS directive (2011/65/EU, (EU)2015/863) for environmental compliance.

Typical Applications

• Industrial power equipment: Bulk filtering and smoothing in power converters and supplies where sustained ripple and elevated operating temperature are present.
• Power supplies: DC link and output filtering in compact, board-mounted power supply modules benefiting from the snap-in radial can form factor.
• Voltage‑fluctuating environments: Equipment operating in areas with unstable input voltages, leveraging the LAK series’ improved safety under abnormal over-voltage.
• General-purpose assemblies: Use in electronic chassis and systems that require a reliable 200 V rated electrolytic in a small footprint.

Unique Advantages

• Proven high-temperature reliability: Endurance validated for 2000 hours at 105°C under rated ripple current, supporting long-term operation in hot environments.
• Robust ripple handling: Defined ripple current ratings (500 mA at 120 Hz, 600 mA at 10 kHz) that help maintain performance in heavy ripple conditions.
• Compact snap-in form factor: 22 × 20 mm radial can with snap-in terminals allows secure mounting and space-efficient placement on power PCBs.
• Designed for abnormal-voltage safety: Pressure-relief vent and safety testing parameters for over-voltage scenarios reduce risk of hazardous failure modes.
• Predictable leakage and tolerance: Leakage current limit formula and ±20% capacitance tolerance aid accurate design margining and inventory selection.
• Environmental compliance: RoHS conformity simplifies regulatory acceptance for commercial and industrial products.
