LAQ2G221MELC30

The LAQ2G221MELC30 is a smaller-sized aluminum electrolytic capacitor with snap-in terminals, offering 220 µF capacitance at a 400 V rating. It is a polarized, general-purpose component designed for applications that require high-voltage capacitance in a compact, snap-in radial can package.

Engineered for extended operation at elevated temperatures, this part is specified for an operating range of -25 °C to +105 °C and a 2000‑hour endurance at 105 °C when subjected to DC bias plus rated ripple current.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance rated at 400 V for high-voltage bulk energy storage in a single component.
• High-temperature endurance — Rated operating temperature -25 °C to +105 °C with a specified 2000 hours endurance at 105 °C under DC bias plus rated ripple current.
• Snap-in radial can package — Snap-in terminal mounting simplifies secure insertion into power assemblies and chassis-mounted designs; package case described as radial, can – snap-in.
• Ripple current ratings — Specified ripple current of 1.24 A at 120 Hz and 1.426 A at 10 kHz to support filtering under AC ripple conditions.
• Leakage and dissipation — Leakage current specified as I ≤ 3√C μA (after 5 minutes at rated voltage, 20 °C) and tan δ ≤ 0.20 (120 Hz, 20 °C), providing defined electrical loss and leakage limits.
• Tolerance & polarity — Capacitance tolerance of -20% to +20% and polarized construction, consistent with common electrolytic capacitor usage.
• Compact footprint — Physical size approximately L: 3 × D: 3.5 cm, allowing denser placement where space is constrained.
• Safety venting — Pressure relief vent designed to operate under abnormal conditions in accordance with the series safety performance statements in the datasheet.

Typical Applications

• General-purpose power circuits — Provides 220 µF at 400 V for general-purpose high-voltage capacitance needs in industrial and electronic equipment.
• High-temperature assemblies — Suitable for designs that require operation up to 105 °C with specified 2000‑hour endurance under rated stress conditions.
• Snap-in power modules — Snap-in radial can format facilitates secure mounting in power modules and assemblies where mechanical retention and density matter.

Unique Advantages

• High-voltage capability: 400 V rating delivers substantial voltage headroom for high-voltage bulk capacitance in a single component.
• Designed for elevated temperatures: Rated to 105 °C with a defined 2000-hour life at that temperature when used under rated bias and ripple conditions.
• Defined ripple performance: Provided ripple current figures at 120 Hz and 10 kHz allow engineers to size the capacitor against expected AC ripple loads.
• Quantified leakage and loss limits: Leakage current and tan δ specifications give clear electrical performance bounds for system-level budgeting.
• Compact, secure mounting: Snap-in radial can package supports robust mechanical retention and simplified assembly in power enclosures.
