LGW2D681MELB25

The LGW2D681MELB25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGW series designed for general‑purpose power electronics. It combines a 680 µF capacitance with a 200 V rated voltage and is optimized for high ripple current performance at elevated temperatures up to 105°C.

This part is suited for applications that require robust ripple‑current handling and long endurance in radial, can‑style snap‑in packaging.

Key Features

• High ripple current capability — Rated ripple current performance of 3.08 A at 120 Hz and 4.62 A at 50 kHz for effective AC stress handling.
• High‑temperature endurance — Designed to withstand application of rated ripple current for 3000 hours at 105°C, providing long service life under continuous thermal and electrical stress.
• Electrical rating — 680 µF nominal capacitance with a 200 V rated voltage and ±20% capacitance tolerance, suitable for bulk energy storage and filtering roles.
• Wide operating temperature range — Specified for operation from −40°C to +105°C (200–250 V range), supporting demanding ambient environments.
• Leakage and dissipation characteristics — Leakage current specified as I ≤ 3√(C·V) μA after 5 minutes at 20°C; tan δ (dissipation factor) max 0.15 for the 200–400 V range (measured at 120 Hz, 20°C).
• Snap‑in radial can package — Radial, snap‑in terminals for secure board mounting and mechanical stability in through‑hole assemblies. Physical size: L 2.5 × D 3 cm.
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supplies — Bulk smoothing and ripple suppression in general‑purpose AC/DC and DC/DC power conversion systems where sustained ripple is present.
• Industrial equipment — Energy storage and filtering in commercial and industrial power electronics that require high ripple endurance at elevated temperatures.
• Energy buffering for converters — Local energy reservoir for converters and inverters in systems that demand sustained current handling over long operating periods.

Unique Advantages

• Designed for sustained high ripple — Rated to endure 3000 hours of rated ripple current at 105°C, delivering predictable performance in continuous high‑stress applications.
• Frequency‑responsive ripple support — Published ripple current values at both low and high frequencies (120 Hz and 50 kHz) enable designers to evaluate performance across typical switching regimes.
• Robust thermal range — −40°C to +105°C operating window for the 200 V variant supports deployment in a wide range of ambient conditions.
• Quantified electrical stability — Capacitance, dissipation factor, and leakage current limits are specified for endurance and shelf‑life conditions, aiding reliability forecasting and design validation.
• Industry‑standard snap‑in mounting — Radial can with snap‑in terminals provides mechanical retention suitable for through‑hole assemblies and ease of placement in production environments.
• RoHS compliance — Meets RoHS requirements for restricted substances, simplifying regulatory considerations for product builds.
