LAQ2D821MELC30ZB

The LAQ2D821MELC30ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LAQ series, specified for general-purpose power electronics. It combines a high 200 V rated voltage with 820 µF capacitance in a compact φ35 × 30 mm can and is supplied in tray packing for mass production.

Designed for applications that require bulk energy storage and smoothing at elevated temperatures, this part offers high ripple handling, controlled leakage, and a 2000-hour endurance rating at 105°C for reliable operation in demanding environments.

Key Features

• Capacitance & Tolerance — 820 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, suitable for bulk filtering and energy storage.
• Voltage Rating — 200 V rated voltage for high-voltage general-purpose circuits.
• Ripple Current — 2.11 A at 120 Hz (low frequency) and 2.532 A at 10 kHz (high frequency), enabling effective handling of AC ripple across a range of switching frequencies.
• Leakage Current — 1210 µA specified leakage current after rated voltage application, useful for predicting standby loss and bias behavior.
• Thermal & Endurance — Operating temperature range of −25°C to +105°C with an endurance rating of 2000 hours at 105°C under DC bias plus rated ripple current.
• Low-Temperature Stability — Impedance stability characterized in the datasheet (impedance ratio max: 8 vs. +20°C), supporting performance at subambient temperatures.
• Mounting & Package — Snap-in terminal radial can (snap-in) for secure board mounting and robust mechanical retention in high-current applications.
• Safety Design — Pressure relief vent design per series specifications to mitigate abnormal pressure conditions without hazardous failure modes.
• Mechanical Size & Packing — Compact φ35 × 30 mm footprint (L: 30 mm × D: 35 mm) and tray packing for production-scale assembly.

Typical Applications

• Power Supplies — Bulk smoothing and energy storage in general-purpose power supplies where 200 V rating and high capacitance are required.
• Power Conversion — DC link and filtering roles in power conversion stages that demand substantial ripple current handling and high-temperature endurance.
• Industrial Electronics — General-purpose energy buffering and decoupling in industrial control and power distribution equipment operating up to 105°C.

Unique Advantages

• High-voltage bulk capacitance: 820 µF at 200 V provides substantial energy storage in a compact snap-in can, reducing the number of components needed for bulk filtering.
• Robust ripple handling: Dual ripple-current ratings (2.11 A at 120 Hz and 2.532 A at 10 kHz) support both low-frequency and high-frequency switching environments.
• Engineered for elevated temperatures: 2000 hours endurance at 105°C ensures predictable performance and longevity under sustained thermal stress.
• Secure board mounting: Snap-in terminals provide mechanical stability for high-current, vibration-prone assemblies.
• Safety-conscious construction: Pressure relief venting reduces the risk of hazardous failure modes under abnormal voltage or temperature conditions.
• Production-ready packaging: Tray packing and mass-production availability simplify procurement and assembly for volume designs.
