LAQ2G221MELC30ZB

The LAQ2G221MELC30ZB is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LAQ series. It provides 220 µF capacitance at a 400 V rated voltage in a radial, can‑style snap‑in package designed for general-purpose power applications.

Engineered for elevated thermal and electrical stress, this part supports operation from -25°C to 105°C and delivers a specified endurance of 2000 hours at 105°C, making it suitable for designs that require high-voltage capacitance with long-term stability.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance at a 400 V rated voltage for high‑voltage energy storage and smoothing in power circuits.
• Tolerance: ±20% capacitance tolerance (at 120 Hz, 20°C), providing predictable performance within common electrolytic tolerance ranges.
• High‑Temperature Endurance: Rated operating temperature range of -25°C to 105°C and an endurance specification of 2000 hours at 105°C under DC bias plus rated ripple current.
• Snap‑in Mounting: Radial can with snap‑in terminals for secure mechanical retention in chassis or module assemblies; designed for board or chassis mounting where robust retention is needed.
• Ripple Current Capability: Specified ripple current of 1.24 A at 120 Hz and 1.426 A at 10 kHz, enabling handling of AC ripple in high‑voltage power applications.
• Electrical Reliability Parameters: Leakage current limit defined by I ≤ 3√C µA after 5 minutes at 20°C; tan δ ≤ 0.20 (120 Hz, 20°C), supporting predictable loss and leakage behavior.
• Safety Feature: Pressure relief vent designed to operate under abnormal conditions to avoid dangerous outcomes such as flame, ignition, or dispersion of case parts.
• Compact Form Factor: Physical size φ35 × 30 mm (diameter × length) for accommodating higher voltage capacitance in a relatively small snap‑in can.

Typical Applications

• General‑Purpose Power Circuits: Bulk energy storage and smoothing in high‑voltage power assemblies where 400 V rated capacitance is required.
• Industrial Power Supplies: Filtering and ripple suppression in industrial power modules operating within -25°C to 105°C.
• AC/DC and DC/DC Converters: High‑voltage input and intermediate bus capacitance where endurance at elevated temperature is needed.

Unique Advantages

• High‑Voltage, High‑Temperature Capability: 400 V rating combined with a 105°C operating limit and 2000 h endurance supports long‑term operation under elevated thermal stress.
• Robust Mounting: Snap‑in radial can design provides mechanical retention suitable for chassis or module installations, simplifying assembly.
• Predictable Electrical Behavior: Defined leakage current limits and tan δ specification allow engineers to size and predict capacitor behavior under real operating conditions.
• Measured Ripple Performance: Published ripple current specifications at 120 Hz and 10 kHz enable accurate thermal and ripple handling calculations during design.
• Safety‑Oriented Design: Pressure relief vent specification reduces risk in abnormal voltage conditions by preventing hazardous failures.
