LGU2G221MELB

The LGU2G221MELB from Nichicon is a snap‑in terminal, aluminum electrolytic capacitor in the LGU series, rated 400 V with 220 µF capacitance and ±20% tolerance. It is a radial, can‑style, snap‑in component designed for general‑purpose applications that require a high‑voltage, high‑reliability electrolytic solution.

Key value comes from its 105°C endurance rating (3000 hours), robust ripple current capability at low and high frequencies, low loss tangent (tan δ = 0.15 at 20°C/120 Hz), and RoHS compliance—providing a combination of long life and high ripple handling in a standard snap‑in package (φ30 × 30L).

Key Features

• Rated Performance — 400 V nominal voltage with 220 µF capacitance and ±20% tolerance, suitable where a high‑voltage electrolytic capacitor is required.
• Thermal Endurance — Rated for operation from −25°C to +105°C with a specified endurance of 3000 hours at 105°C when subjected to DC bias plus rated ripple current.
• High Ripple Current Capability — Supports 1.100 A ripple at 120 Hz (low frequency) and 1.573 A at 50 kHz (high frequency), with frequency coefficients provided by the LGU series data.
• Low Dissipation Factor — tan δ = 0.15 (max) measured at 20°C and 120 Hz for the 160–420 V rating range, indicating low AC loss under rated conditions.
• Leakage Current — Measured leakage current of 880 µA under specified test conditions, with datasheet limits defined by capacitance and voltage.
• Mechanical & Mounting — Snap‑in terminal, radial can package (φ30 × 30L) for secure board mounting; supplied in tray packing and in mass production status.
• Compliance — RoHS compliant per product documentation.

Typical Applications

• General‑purpose systems — For designs that require a 400 V, 220 µF snap‑in aluminum electrolytic capacitor with ±20% tolerance.
• High‑temperature deployments — For equipment operating within −25°C to +105°C, where the capacitor’s 3000‑hour endurance at 105°C provides predictable aging characteristics.
• High‑ripple environments — For circuits subject to significant ripple current, leveraging the 1.100 A (120 Hz) and 1.573 A (50 kHz) ripple ratings.

Unique Advantages

• High voltage capability: 400 V rating enables use in higher‑voltage general‑purpose applications without requiring series stacking or additional components.
• Long thermal life: 3000 hours endurance at 105°C reduces maintenance and replacement frequency in sustained high‑temperature service.
• Broad ripple performance: Specified ripple current at both low and high frequencies supports a range of switching and line‑frequency environments.
• Low loss under AC excitation: tan δ = 0.15 at 20°C/120 Hz reduces heating and improves efficiency in AC‑loaded circuits.
• Board‑secure mounting: Snap‑in radial can design provides robust mechanical retention for through‑hole assemblies.
• Regulatory alignment: RoHS compliance supports environmentally constrained designs.
