LAQ2G221MELB35ZB

The LAQ2G221MELB35ZB from Nichicon is a snap‑in terminal type aluminum electrolytic capacitor in the LAQ series, offering 220 µF capacitance at a 400 V rating. It is designed for general‑purpose applications where a compact, high‑voltage electrolytic capacitor with robust ripple handling and elevated temperature endurance is required.

Key design characteristics include snap‑in radial can packaging (φ30 × 35 mm), a wide operating temperature range of −25 °C to +105 °C, and a guaranteed endurance of 2000 hours at 105 °C under rated conditions.

Key Features

• Capacitance & Tolerance — 220 µF nominal capacitance with ±20% tolerance, suitable for designs specifying this capacitance range.
• High Voltage Rating — Rated at 400 V for high‑voltage applications within the specified category.
• Snap‑in Radial Can Package — Snap‑in mounting style and radial can package (φ30 × 35 mm) for secure panel/board installation and easy mechanical mounting.
• Ripple Current Performance — Rated ripple current of 1.240 A at 120 Hz (low frequency) and 1.426 A at 10 kHz (high frequency) for effective AC ripple handling.
• Low Leakage — Specified leakage current of 880 µA, measured after voltage application per product specification.
• High Temperature Endurance — Endurance rating of 2000 hours at 105 °C when subjected to D.C. bias plus rated ripple current, with post‑test limits on capacitance, tan δ and leakage current defined in the series specifications.
• Operating Temperature Range — −25 °C to +105 °C to support elevated ambient conditions.
• Safety Vent — Pressure relief vent designed to operate under abnormal conditions as specified in the LAQ series safety performance requirements.
• Production Packaging — Supplied in tray packing and indicated as mass production availability for volume manufacturing needs.
• Polarized Device — Polarized electrolytic capacitor; observe polarity in application.

Typical Applications

• General‑Purpose Power Electronics — Used where a 400 V, 220 µF polarized capacitor is required for bulk capacitance and ripple accommodation in general‑purpose circuits.
• High‑Temperature Environments — Suitable for equipment operating up to 105 °C where 2000‑hour endurance at elevated temperature is needed.
• Volume Manufacturing — Tray packing and mass‑production availability make it appropriate for repetitive assembly processes.

Unique Advantages

• High Voltage Capacity: 400 V nominal rating supports designs that require elevated DC voltage headroom.
• Robust Ripple Handling: Specified ripple currents at both 120 Hz and 10 kHz provide measurable performance for AC ripple environments.
• Elevated Endurance: 2000 hours at 105 °C under rated conditions gives a quantified lifetime metric for thermal stress planning.
• Compact Snap‑in Form Factor: φ30 × 35 mm radial can with snap‑in terminals combines high voltage with a smaller footprint for space‑constrained assemblies.
• Manufacturing‑Friendly Packaging: Tray packing supports volume production workflows and repeatable handling.
• Safety‑Minded Design: Pressure relief vent as specified in the LAQ series safety performance reduces risk under abnormal voltage conditions.
