LAK2G221MELB35ZB

The LAK2G221MELB35ZB is a snap‑in terminal aluminum electrolytic capacitor in Nichicon’s LAK series, specified for high‑voltage, general‑purpose applications. It combines a 400 V rated voltage with 220 µF capacitance in a radial, snap‑in can designed for equipment exposed to fluctuating voltages.

Engineered for operation from -25°C to +105°C and RoHS compliant, this component provides high ripple endurance and durability where elevated temperature performance and safety under abnormal voltage conditions are required.

Key Features

• Capacitance & Voltage — 220 µF capacitance with a 400 V rated voltage and ±20% tolerance (120 Hz, 20°C), suitable where a high DC voltage rating is needed.
• Snap‑in Terminal / Radial Can — Snap‑in mounting type in a radial, can‑style package for secure mechanical retention in power assemblies.
• High Temperature Endurance — Rated for continuous operation from -25°C to +105°C with an endurance specification of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current of 900 mA at 120 Hz (105°C) and 1.035 A at 10 kHz, enabling sustained performance under AC ripple stress.
• Leakage and Loss Characteristics — Leakage current I ≤ 3√(C·V) µA after 5 minutes at 20°C; tangent of loss angle (tan δ) max 0.20 at 120 Hz, 20°C.
• Safety Features — LAK series design includes improved safety for abnormally excessive voltage and a pressure relief vent that operates without flames or dangerous dispersion.
• Physical Dimensions — Compact radial can: L: 3.5 × D: 3 cm, snap‑in package suitable for high‑voltage board assemblies.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Electronic Equipment — Use where a 400 V, 220 µF polarized capacitor is required and operation across -25°C to +105°C is expected.
• Equipment Subject to Voltage Fluctuation — Designed with improved safety measures for abnormally excessive voltage, making it suitable for systems that experience line or load voltage variations.
• High‑Voltage Power Modules and Assemblies — Snap‑in radial can and high DC rating simplify integration into high‑voltage power assemblies that require sustained ripple capability.

Unique Advantages

• Robust High‑Voltage Support: 400 V rating (part of an extended 200 V / 400 V / 420 V family) enables use in higher DC voltage designs without up‑rating multiple components.
• Elevated‑Temperature Reliability: Endurance tested for 2000 hours at 105°C with defined limits for capacitance change, tan δ and leakage current, supporting long‑term operation in hot environments.
• High Ripple Endurance: Rated ripple currents of 900 mA (120 Hz) and 1.035 A (10 kHz) provide predictable performance under AC ripple stress common in power electronics.
• Enhanced Safety Design: Series‑level safety features and an operational pressure relief vent reduce risk under abnormal voltage conditions.
• Board‑Ready Snap‑In Package: Snap‑in terminals and radial can packaging allow secure mounting for power assemblies and modules.
• RoHS Compliance: Conforms to RoHS (2011/65/EU, (EU)2015/863) for environmentally conscious designs.
