Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 400 V for high-voltage smoothing and energy storage.
• High-Temperature Endurance — Rated for operation to +105°C with a specified 2000 hours life under rated ripple and D.C. bias.
• Ripple Current Performance — Handles 1.24 A at 120 Hz and 1.426 A at 10 kHz, supporting both low- and high-frequency ripple conditions.
• Leakage Current — Specified leakage current of 880 µA, suitable for applications requiring predictable off-state current.
• Safety Design — Includes pressure relief vent behavior per series safety performance to reduce risk under abnormal voltage conditions.
• Package & Mounting — Radial snap-in can (φ30 × 35 mm) for secure board mounting and mechanical stability; supplied in tray packing for volume production.
• Tolerance & Polarization — ±20% capacitance tolerance at 120 Hz, 20°C; polarized device for DC applications.
• Regulatory — LAQ series is compliant with the RoHS directive (2011/65/EU, (EU)2015/863) as noted in the series datasheet.

Typical Applications

• High-voltage power systems — Bulk smoothing and energy storage in systems requiring a 400 V rated capacitor with high ripple capability.
• Voltage‑fluctuating equipment — Designed for equipment operating in areas with supply fluctuations thanks to improved safety features and 105°C endurance.
• Industrial power modules — Board-mounted snap-in package and high ripple ratings support use in industrial power supplies and converters.
• General-purpose electronic equipment — Suitable for general-purpose DC filtering where a polarized, high-voltage electrolytic capacitor is required.

Unique Advantages

• 400 V rating with substantial capacitance — Enables compact high-voltage energy storage in applications that require both voltage headroom and capacitance.
• High ripple tolerance across frequencies — Specified ripple currents at 120 Hz and 10 kHz provide predictable thermal and electrical performance under both low- and high-frequency ripple loading.
• Long endurance at elevated temperature — 2000 hours life at 105°C under rated ripple and DC bias offers extended service life in demanding thermal environments.
• Robust safety characteristics — Series safety performance and pressure relief design reduce the risk of hazardous failures under abnormal voltage conditions.
• Production-ready packaging — Tray packing and mass-production availability simplify procurement and assembly for volume manufacturing.
• RoHS compliance — Meets the RoHS directive as documented for the LAQ series, supporting regulatory requirements for many commercial products.
