LAK2G101MELZ35

The LAK2G101MELZ35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LAK series, specified for high-voltage, high-temperature applications. It provides 100 µF capacitance at a 400 V rating with polarization and is designed for equipment exposed to fluctuating voltages.

Key value propositions include endurance under elevated temperature and ripple stress (2000 hours at 105°C with rated ripple current), improved safety features for abnormal overvoltage conditions, and RoHS compliance.

Key Features

• Capacitance & Voltage — 100 µF capacitance rated at 400 V for high‑voltage energy storage and smoothing.
• High‑temperature Endurance — Specified to operate from −25°C to +105°C with an endurance rating of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Handling — Rated ripple current of 550 mA at 120 Hz and 632.5 mA at 10 kHz, supporting sustained AC ripple stress at elevated temperatures.
• Safety & Abnormal Voltage Performance — Permissible abnormal voltage design and improved safety features (including a pressure relief vent behavior specified in the LAK series) to mitigate hazardous failure modes under excessive voltage conditions.
• Mounting & Package — Snap‑in terminal, radial can (snap‑in) package for robust board retention and easy insertion into high‑power assemblies.
• Form Factor — Physical size L: 3.5 × D: 2.2 cm with a maximum seated height of 1.378 inch, suited for larger‑footprint power applications where high voltage capacity is required.
• Polarized Device — Polarized construction for DC bulk storage and smoothing applications.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑voltage power supplies — Bulk energy storage and smoothing in 400 V rails, benefiting from the capacitor’s rated voltage and ripple capability.
• Industrial power conversion — Use in inverters, converters, and motor drive systems where equipment is exposed to voltage fluctuations and elevated operating temperatures.
• UPS and energy storage modules — Provides high‑voltage capacitor support for short‑term energy buffering and ripple filtering under sustained thermal stress.

Unique Advantages

• High thermal and ripple endurance: Designed to withstand 2000 hours of rated ripple current at 105°C, providing reliable performance in hot operating environments.
• 400 V rating for high‑voltage systems: Supports designs requiring 400 V DC bulk capacitance without needing multiple lower‑voltage components in series.
• Abnormal voltage safety features: Improved safety design and pressure relief behavior reduce the risk of dangerous outcomes during excessive voltage events.
• Snap‑in package for secure mounting: Radial snap‑in can offers strong board retention for high‑vibration or high‑power assemblies.
• Clear specification set for engineering: Published metrics for capacitance, tolerance (±20%), leakage current formula, tan δ, and ripple current enable straightforward integration and verification.
