LAQ2P221MELA25

The LAQ2P221MELA25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LAQ series, offering 220 µF capacitance at a 220 V rating in a compact φ25 × 25 mm can. Designed for general‑purpose power applications, it provides high ripple handling, long endurance at elevated temperatures, and built‑in safety features for operation in environments with fluctuating voltages.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 220 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High Ripple Current — 900 mA low‑frequency ripple current (120 Hz) and 1.08 A high‑frequency ripple current (10 kHz) to support power filtering and decoupling in high‑ripple circuits.
• Endurance at Elevated Temperature — Rated for 2000 hours at 105°C with DC bias plus rated ripple current, meeting LAQ series endurance criteria for capacitance, tan δ and leakage.
• Leakage Current — Low leakage current of 660 µA (measured after rated voltage application), supporting stable bias conditions in power supplies and control circuits.
• Package & Mounting — Radial, snap‑in can package (φ25 × 25 mm) for secure board mounting and simplified assembly in power supply modules and industrial equipment.
• Temperature Range — Operates from −25°C to +105°C for use across a wide range of ambient conditions.
• Safety Features — Improved safety design with a pressure relief vent to operate without ignition or dispersion under abnormal voltage conditions.
• Packaging & Production — Tray packing and mass production status for predictable supply and PCB assembly flow.
• RoHS Compliance — LAQ series is compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supplies and converters — Bulk filtering and smoothing for intermediate DC rails where 220 V rating and high ripple handling are required.
• Industrial control equipment — Energy buffering and decoupling in motor control, drive electronics, and factory automation systems operating across −25°C to +105°C.
• Consumer appliances with high‑voltage circuits — EMI/RFI filtering and ripple suppression in mains‑related power circuits that benefit from long 105°C endurance.

Unique Advantages

• High thermal endurance: 2000 hours at 105°C ensures long life under elevated temperature and continuous ripple stress.
• Robust ripple performance: Dual ripple ratings (900 mA at 120 Hz and 1.08 A at 10 kHz) provide predictable filtering across low and high frequencies.
• Compact snap‑in form factor: φ25 × 25 mm radial can with snap‑in terminals simplifies PCB mounting while saving board space.
• Defined leakage behavior: Specified leakage current (660 µA) aids in predictable bias and hold‑up calculations for power designs.
• Safety‑oriented construction: Pressure relief vent and series safety testing mitigate risks from abnormal voltage conditions.
• Production ready: Tray packing and mass production status support consistent procurement and assembly planning.
