LGW2D821MELA40

The LGW2D821MELA40 is an aluminum electrolytic capacitor from Nichicon's LGW series featuring a snap‑in terminal package and a rated capacitance of 820 µF at 200 V. It is specified for general‑purpose applications where robust ripple handling and extended high‑temperature endurance are required.

Designed for continuous operation up to 105°C, this part delivers high ripple current capability, low dissipation factor, and controlled leakage—making it suitable for designs that demand reliable bulk capacitance in a radial, snap‑in can (φ25 × 40 mm) form factor. The part is RoHS compliant and in mass production with tray packing.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance at a 200 V rated voltage with ±20% tolerance at 120 Hz, 20°C.
• High Ripple Current — Rated ripple current of 3.08 A at 120 Hz (low frequency) and 4.62 A at 50 kHz (high frequency), supporting designs with elevated AC stress on bulk capacitors.
• Endurance at Elevated Temperature — Specified endurance of 3000 hours at 105°C with DC bias plus rated ripple current applied; parameters are measured after recovery to 20°C.
• Low Loss — Tangent of loss angle (tan δ) specified at 0.15 (max.) for 200 V at 120 Hz and 20°C, indicating low dielectric losses for improved efficiency.
• Controlled Leakage — Leakage current listed as 1210 µA; datasheet provides standard leakage limits and test conditions.
• Package & Mounting — Snap‑in terminal radial can (φ25 × 40 mm) for secure mechanical mounting and simplified assembly in panel and chassis layouts.
• Regulatory Compliance & Availability — RoHS compliant and available in tray packing; part is in mass production.

Typical Applications

• Power systems — General‑purpose power designs requiring 820 µF bulk capacitance at 200 V and substantial ripple current capability.
• Power conversion — DC‑link or smoothing stages where high ripple current endurance and 105°C rated operation improve reliability under thermal stress.
• Industrial equipment — General‑purpose industrial electronics that benefit from long endurance (3000 h at 105°C) and RoHS compliance.
• General electronic systems — Applications needing polarized aluminum electrolytic bulk capacitance in a snap‑in radial can package (φ25 × 40 mm).

Unique Advantages

• Designed for high ripple environments: Rated ripple currents of 3.08 A (120 Hz) and 4.62 A (50 kHz) enable sustained AC loading without premature degradation.
• Extended high‑temperature life: 3000‑hour endurance at 105°C under rated ripple and DC bias provides predictable long‑term performance in hot operating environments.
• Low dissipation factor: tan δ ≤ 0.15 at 120 Hz helps reduce heating and loss in applications where efficiency matters.
• Compact radial snap‑in format: φ25 × 40 mm can with snap‑in terminals simplifies mounting and is appropriate for higher‑volume, repeatable assembly workflows.
• RoHS compliant and production ready: Meets RoHS requirements and is available in tray packing for streamlined procurement and handling.
