LAQ2D122MELC40

The LAQ2D122MELC40 is an aluminum electrolytic capacitor from Nichicon’s LAQ series with a snap-in terminal radial can. It delivers 1.2 mF capacitance at a 200 V rating with a compact φ35 × 40 mm package and polarized mounting for general-purpose designs.

Engineered for high-temperature operation and sustained ripple loading, this part supports up to 2.65 A ripple at 120 Hz and 3.18 A at 10 kHz, a 105°C operating limit with 2000 hours endurance, and tray packing for production handling.

Key Features

• Electrical performance — 1.2 mF (±20%) capacitance at 200 V rated voltage provides substantial energy storage for smoothing and decoupling in high-voltage circuits.
• High ripple capability — Rated ripple current of 2.65 A (120 Hz) and 3.18 A (10 kHz) supports continuous AC loading within specified frequencies.
• High-temperature endurance — Rated for -25°C to 105°C with a 2000 hour endurance at 105°C under DC bias plus rated ripple current; capacitance change and tan δ limits defined by the LAQ series specification.
• Low dissipation and leakage — Specified tan δ 0.20 max (120 Hz, 20°C) and initial leakage current value provided (1,460 µA), with defined recovery/shelf-life behavior per series data.
• Snap-in radial package — φ35 × 40 mm can with snap-in terminals for robust mechanical mounting and straightforward assembly into power assemblies.
• Safety features — Pressure relief vent per LAQ series safety performance to help prevent dangerous conditions under abnormal stress.
• Production-friendly packaging — Tray packing and mass production status support high-volume assembly workflows.

Typical Applications

• General-purpose power supply filtering — Bulk smoothing and ripple reduction where a 200 V, 1.2 mF capacitor is required and sustained ripple currents occur.
• High-temperature equipment — Use in systems that require component operation up to 105°C with defined 2000 hour endurance under rated conditions.
• Power conversion subsystems — Energy storage and filtering in assemblies that need polarized, snap-in radial cans for reliable mechanical mounting.

Unique Advantages

• Robust ripple handling: Specified ripple currents at both low and high frequencies allow designers to size capacitors with measured confidence for thermal and life calculations.
• High-voltage capability: 200 V rated voltage with 1.2 mF capacitance reduces the need for parallel banks in medium-voltage designs.
• High-temperature endurance: 105°C rating and 2000 hour life under rated conditions provide predictable long-term behavior in warm environments.
• Compact snap-in format: φ35 × 40 mm radial can with snap-in terminals simplifies assembly and provides mechanical stability on power boards.
• Defined safety behavior: Pressure relief vent and series-level safety tests reduce the risk of hazardous failure modes under abnormal conditions.
• Production-ready packaging: Tray packing and mass-production status streamline procurement and assembly for volume programs.
