LAQ2D821MELC30

The LAQ2D821MELC30 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAQ series, rated 820 µF with a 200 V working voltage. Designed for general‑purpose use, it delivers high capacitance in a compact φ35 × 30 mm radial can with snap‑in mounting and tray packing for mass production.

Key electrical characteristics include ±20% capacitance tolerance, low‑frequency ripple current of 2.11 A (120 Hz), high‑frequency ripple current of 2.532 A (10 kHz), a leakage current of 1210 µA, and a 2000‑hour endurance at 105°C with an operating temperature range of −25°C to +105°C.

Key Features

• High Capacitance & Voltage: 820 µF capacitance at a 200 V rated voltage provides substantial bulk energy storage for higher‑voltage systems.
• Snap‑in Radial Can Package: Snap‑in terminal type in a φ35 × 30 mm radial can offers secure board mounting and straightforward installation for mass production assemblies.
• Ripple Current Performance: Rated ripple currents of 2.11 A at 120 Hz and 2.532 A at 10 kHz support both low‑frequency and high‑frequency ripple handling requirements.
• Leakage Current: Specified leakage current of 1210 µA, measured after rated voltage application, for predictable standby and no‑load behavior.
• High‑Temperature Endurance: Rated for 2000 hours at 105°C under D.C. bias plus rated ripple current, with capacitance change and leakage current meeting LAQ series endurance criteria.
• Wide Operating Range: Operational from −25°C to +105°C, enabling deployment in applications that require higher temperature tolerance.
• Tolerance & Stability: ±20% capacitance tolerance at 120 Hz, 20°C, consistent with LAQ series specifications for stability and reliability.

Typical Applications

• General Power Supplies: Bulk capacitance and 200 V rating suit smoothing and energy storage in higher‑voltage general‑purpose power supply circuits.
• Industrial Electronics: High ripple current capability and 105°C endurance support long‑life operation in industrial equipment where elevated temperatures and sustained ripple are present.
• Power Conversion Modules: The combination of 820 µF capacitance and robust ripple handling is useful for DC link and filtering roles in power conversion assemblies.

Unique Advantages

• High Voltage Handling: 200 V rating enables use in higher‑voltage circuits without sacrificing bulk capacitance.
• Compact, Production‑Friendly Form: φ35 × 30 mm snap‑in can packaged in trays for efficient automated assembly and consistent mechanical retention.
• Designed for Elevated Temperatures: 2000 hours life at 105°C provides predictable long‑term performance under thermal stress.
• Dual‑Frequency Ripple Support: Specified ripple currents at both 120 Hz and 10 kHz allow designers to evaluate performance across common ripple spectra.
• Controlled Leakage: Specified leakage current figure (1210 µA) gives a measurable baseline for no‑load and standby current budgeting.
