LAQ2D821MELA50

The LAQ2D821MELA50 is a Nichicon LAQ series aluminum electrolytic capacitor in a snap-in terminal (radial can) package. It provides 820 µF capacitance with ±20% tolerance and a 200 V rated voltage, optimized for general-purpose power applications requiring robust ripple handling and long-term endurance.

Designed for mass production and tray packing, this component targets power electronics, industrial controls and other systems that need high-voltage bulk capacitance with reliable thermal and safety characteristics.

Key Features

• Capacitance & tolerance — 820 µF with ±20% tolerance at 120 Hz, 20°C for bulk energy storage and smoothing.
• Rated voltage — 200 V DC rating suitable for higher-voltage power rails.
• Ripple current performance — 2.11 A at 120 Hz (low frequency) and 2.532 A at 10 kHz (high frequency) to support AC ripple filtering and decoupling under load.
• Leakage current — Specified leakage current of 1210 µA after rated-voltage application, supporting predictable standby and idle behavior.
• Temperature & endurance — Operating range −25°C to +105°C with 2000 hours endurance at 105°C per LAQ series specification.
• Package & mounting — Radial snap-in can (φ25 × 50 mm / L:5 × D:2.5 cm) for secure PCB mounting and assembly; supplied in tray packing for production throughput.
• Electrical stability — Loss tangent (tan δ) up to 0.20 (120 Hz, 20°C) and low-temperature impedance stability with an impedance ratio up to 8 at −25°C versus +20°C per series data.
• Safety design — Series safety performance includes a pressure relief vent engineered to operate without generating dangerous conditions under abnormal voltage or fault scenarios.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple reduction on high-voltage DC rails where 200 V rating and multi-amp ripple capability are required.
• Industrial power electronics — Energy storage and decoupling in motor drives, control power modules and converters operating up to 105°C.
• UPS and backup systems — Bulk capacitance for ride-through and transient support in medium-voltage backup circuits.

Unique Advantages

• High-voltage capability: 200 V rating enables use on elevated DC rails without series stacking.
• Strong ripple handling: Dual-frequency ripple specifications (2.11 A at 120 Hz and 2.532 A at 10 kHz) provide predictable performance across common switching and line frequencies.
• Thermal endurance: Rated for 2000 hours at 105°C, supporting sustained operation in elevated-temperature environments.
• Robust mechanical mounting: Snap-in radial can and tray packing simplify PCB retention and high-volume assembly processes.
• Predictable leakage and dielectric loss: Specified leakage current and tan δ limit enable easier system-level power budgeting and thermal design.
• Safety venting: Pressure relief vent design reduces risk under abnormal voltage conditions, improving field reliability.
