LAK2G221MELA45

The LAK2G221MELA45 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LAK series. It delivers 220 µF capacitance at a 400 V rating in a radial, can-style snap‑in package intended for general-purpose power applications.

Designed for equipment exposed to fluctuating voltages, the LAK series emphasizes high-temperature ripple endurance and improved safety for abnormally excessive voltage conditions, with RoHS compliance for environmental requirements.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 400 V rated voltage and tolerance of ±20% (−20% to +20%).
• High‑Temperature Endurance — Rated for operation from −25°C to 105°C with an endurance specification of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Performance — Specified ripple capability of 900 mA at 120 Hz and 1.035 A at 10 kHz, supporting applications with steady ripple loading.
• Safety Performance — Improved safety features for abnormally excessive voltage including a pressure relief vent designed to operate without flame, ignition, or dispersion of parts under the defined test conditions.
• Leakage and Loss Characteristics — Leakage current specified as I ≤ 3√(C·V) µA after 5 minutes at 20°C; tangent of loss angle (tan δ) limited to 0.20 maximum at 120 Hz and 20°C.
• Package & Mounting — Radial, can-style snap‑in package with dimensions L: 4.5 × D: 2.5 cm for secure PCB mounting in power assemblies.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Filtering — Bulk smoothing and decoupling in equipment that experiences fluctuating supply voltages.
• Industrial Power Equipment — Components for power modules and control systems requiring sustained ripple endurance at elevated temperatures.
• High‑Voltage DC Circuits — Energy storage and smoothing in circuits up to the 400 V rating.
• Chassis and Panel‑Mount Power Assemblies — Snap‑in radial can package for robust mechanical retention in power racks and modules.

Unique Advantages

• High‑temperature ripple endurance: 2000 hours at 105°C under rated ripple current supports reliability in thermally demanding environments.
• 400 V capability: Enables use in higher-voltage DC applications while maintaining 220 µF bulk capacitance.
• Designed safety behavior: Pressure relief vent and defined safety performance reduce risk under abnormal overvoltage conditions.
• Measurable electrical stability: Endurance limits (capacitance change within ±20%, controlled tan δ and leakage) provide predictable aging and performance.
• Robust mechanical mounting: Snap‑in radial can format simplifies secure installation in power assemblies and racks.
• RoHS compliant: Meets environmental substance requirements for regulated markets.
