LAQ2P221MELB20ZB

The LAQ2P221MELB20ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LAQ series, rated at 220 µF with a nominal voltage of 220 V. Designed for general-purpose power applications, it delivers compact energy storage and filtering with a snap-in radial can package for secure board mounting.

Key value propositions include high ripple handling, extended endurance at elevated temperature, and a compact φ30 × 20 mm footprint suitable for industrial and commercial power electronics requiring reliable DC filtering and smoothing.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 220 V rated voltage and ±20% tolerance, providing predictable bulk energy storage and filtering performance.
• High Ripple Capability — Rated ripple current of 900 mA at 120 Hz and 1.08 A at 10 kHz, allowing effective smoothing in both low-frequency and higher-frequency power circuits.
• Endurance at Elevated Temperature — 2000 hours rated life at 105°C under D.C. bias plus rated ripple current, meeting demanding thermal endurance requirements.
• Low Leakage — Specified leakage current of 660 µA, supporting low-loss performance after application of rated voltage.
• Snap-in Radial Can Package — Robust snap-in terminal type (radial, can - snap-in) for secure mechanical mounting and easy insertion into power assemblies.
• Operating Temperature Range — Specified for operation from -25°C to +105°C, suitable for a wide range of commercial and industrial environments.
• Safety Vent — Pressure relief vent is provided to operate under abnormal conditions to reduce risk of dangerous failures.
• Compact Size — φ30 × 20 mm (D × L) footprint and 20 mm seated height helping save board space in power modules and assemblies.

Typical Applications

• Power supply filtering — Bulk smoothing and decoupling in commercial and industrial AC–DC and DC–DC power supplies.
• Hold-up and energy storage — Short-term energy storage and hold-up in systems requiring moderate capacitance at 220 V.
• Industrial control equipment — Filtering and ripple suppression for drives, inverters, and control power rails within the stated temperature and endurance limits.

Unique Advantages

• High-voltage capability: 220 V rating allows use in higher-voltage power rails and DC link applications where moderate capacitance is required.
• Robust ripple performance: Specified ripple currents at both 120 Hz and 10 kHz enable use in switching and line-frequency applications without excessive heating.
• Long endurance at high temperature: 2000 hours at 105°C under rated conditions provides predictable lifetime performance for thermal-stressed designs.
• Secure board mounting: Snap-in radial can package simplifies assembly and provides mechanical stability in power modules and chassis-mounted electronics.
• Compact footprint: φ30 × 20 mm size balances capacitance and board space, aiding density-constrained designs.
• Safety-minded design: Built-in pressure relief vent reduces risk during abnormal voltage or stress conditions.
