LAQ2D821MELB35

The LAQ2D821MELB35 is a Nichicon LAQ series aluminum electrolytic capacitor in a snap-in, radial can package. It delivers 820 µF capacitance at a 200 V rating and is designed for general-purpose power applications that require compact, high-voltage bulk capacitance.

Engineered for elevated operating temperatures, this snap-in capacitor supports an operating range from -25 °C to 105 °C and is specified for extended endurance under rated DC bias and ripple conditions.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 200 V rated voltage, suitable for high-voltage bulk storage in general-purpose power designs.
• Temperature Range — Specified operation from -25 °C to +105 °C with permissible abnormal voltage at 105 °C for the LAQ series.
• Endurance & Lifetime — Endurance specification: performance maintained after 2000 hours at 105 °C under D.C. bias plus rated ripple current (capacitance within ±20% of initial value).
• Ripple Current Capability — Rated ripple handling of 2.11 A at 120 Hz and 2.532 A at 10 kHz, enabling effective smoothing under AC ripple conditions.
• Leakage Current Specification — Leakage current meets the series formula I ≤ 3√C (μA) after 5 minutes at 20 °C (C = rated capacitance in μF), providing quantifiable leakage expectations.
• Electrical Loss (tan δ) — tan δ specified at 0.20 max (120 Hz, 20 °C), with post-endurance and shelf-life limits defined in the series specifications.
• Package & Mounting — Radial, snap‑in can package for secure PCB mounting and mechanical stability in vertical assemblies.
• Polarized Design — Polarized electrolytic construction for correct DC-oriented circuit placement.
• Physical Size — Compact footprint: approximately L: 3.5 × D: 3 cm for space-conscious power assemblies.
• Safety Features — Series includes pressure relief vent functionality to mitigate hazardous failure modes under abnormal conditions.

Typical Applications

• Power supplies and DC filtering — Provides 820 µF at 200 V for bulk smoothing and energy storage in general-purpose power supply circuits.
• Industrial power equipment — Suitable where elevated operating temperature tolerance (up to 105 °C) and defined ripple capability are required for stable operation.
• General-purpose high-voltage circuits — Snap-in radial package offers a robust mounting option for high-voltage DC circuits needing reliable capacitance.

Unique Advantages

• High-voltage bulk capacitance: 820 µF at 200 V provides significant stored energy for smoothing and decoupling in high-voltage DC circuits.
• Elevated temperature endurance: Rated for operation up to 105 °C with a 2000-hour endurance specification, supporting sustained performance in hot environments.
• Defined ripple performance: Published ripple current ratings at 120 Hz and 10 kHz allow designers to match the capacitor to expected ripple conditions.
• Predictable leakage behavior: Leakage current bounded by the series formula (I ≤ 3√C µA after 5 minutes at 20 °C) for predictable standby losses.
• Secure snap-in mounting: Radial snap‑in can reduces mechanical stress on solder joints and simplifies insertion into vertical power assemblies.
• Series-level safety design: Pressure relief venting reduces the risk of dangerous failure modes under abnormal conditions.
