LAQ2G820MELZ30ZB

The LAQ2G820MELZ30ZB is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LAQ series. It provides 82 µF capacitance at a 400 V rating in a compact φ22 × 30 mm can designed for high‑temperature operation up to 105°C.

Designed for general‑purpose power applications, this snap‑in radial capacitor delivers packaged ripple handling, low leakage and endurance for demanding board‑level DC filtering and bulk energy storage requirements.

Key Features

• Capacitance & Voltage: 82 µF capacitance with a rated voltage of 400 V and ±20% tolerance, suitable for high‑voltage DC bus and filtering applications.
• High‑temperature Endurance: Rated for operation from −25°C to 105°C with a 2000 hour endurance at 105°C under DC bias plus rated ripple current.
• Snap‑in, Radial Can Package: Snap‑in terminal type in a radial can (φ22 × 30 mm) for secure board mounting and robust mechanical retention in power assemblies.
• Ripple Current Capacity: Low frequency ripple current 580 mA at 120 Hz and high frequency ripple current 667 mA at 10 kHz, supporting DC link smoothing and ripple suppression.
• Leakage & Dielectric Loss: Specified leakage current 540 µA and series tan δ limit (tan δ ≤ 0.20 at 120 Hz, 20°C) for predictable DC performance.
• Safety & Reliability: Pressure relief vent design and series safety performance testing to mitigate abnormal conditions; RoHS compliant.
• Production‑ready Packaging: Supplied in tray packing and listed as mass production status for volume manufacturing.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and DC bus decoupling where 400 V rating and 82 µF capacitance are required for stable power delivery.
• Inverters and Motor Drives: Energy buffering and ripple suppression on high‑voltage stages that operate at elevated ambient temperatures.
• Power Conversion Modules: Filtering and hold‑up in high‑voltage converters and switched‑mode power supplies that demand robust ripple handling.

Unique Advantages

• High Voltage Capability: 400 V rating enables use directly on high‑voltage DC rails without additional series components.
• Compact Footprint: φ22 × 30 mm package delivers 82 µF in a small radial can, helping to save board space in dense power assemblies.
• Designed for Elevated Temperatures: 105°C maximum operating temperature and 2000 h endurance at 105°C provide predictable life under thermal stress.
• Reliable Mounting: Snap‑in terminals offer secure mechanical retention for through‑panel or board installations in industrial environments.
• Measured Ripple Performance: Specified ripple current figures at 120 Hz and 10 kHz allow designers to size capacitors against actual ripple loads.
• RoHS Compliant: Meets environmental regulations for lead‑free assembly and global production requirements.
