LGU2E681MELB

The LGU2E681MELB is a Nichicon LGU series snap-in aluminum electrolytic capacitor featuring 680 µF capacitance and a 250 V rated voltage. It is a polarized, snap-in radial can designed for general-purpose power applications that require robust ripple handling and long-term high-temperature endurance.

Key delivered performance includes a rated operating temperature range of −40 °C to 105 °C, endurance of 3000 hours at 105 °C, low- and high-frequency ripple current capability, and RoHS compliance. The part is supplied in tray packing and is in mass production.

Key Features

• Capacitance and Tolerance — 680 µF nominal capacitance with ±20% tolerance (120 Hz, 20 °C) for predictable bulk energy storage and filtering.
• Rated Voltage — 250 V DC rated voltage suitable for medium-voltage power circuits requiring polarized aluminum electrolytic support.
• High-Temperature Endurance — Designed to meet endurance requirements of 3000 hours at 105 °C under rated ripple and DC bias conditions.
• Ripple Current Capability — Low-frequency ripple current: 2.0 A (120 Hz); high-frequency ripple current: 3.0 A (50 kHz) to accommodate a range of switching and line-frequency environments.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) of 0.15 (measured at 20 °C, 120 Hz) and a specified leakage current of 1230 µA after rated voltage application.
• Mechanical and Packaging — Snap-in radial can package (φ30 × 40 mm length) for secure board mounting; supplied in tray packing for production handling.
• Operating Range and Polarization — Polarized capacitor rated for −40 °C to 105 °C operation, suitable for sustained elevated temperature operation within that range.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and smoothing in power supplies and DC link circuits where a 680 µF, 250 V polarized capacitor is required.
• Industrial power electronics — Suitable for general-purpose use in equipment that demands sustained operation up to 105 °C and reliable ripple performance.
• OEM assemblies — Fits into production builds where tray-packed, snap-in radial cans are preferred for mechanical stability and assembly throughput.

Unique Advantages

• Long high-temperature life — 3000 hours endurance at 105 °C supports designs requiring extended operation under elevated temperature conditions.
• Broad ripple performance — Specified ripple currents at both low (2.0 A at 120 Hz) and high frequencies (3.0 A at 50 kHz) give flexibility across switching and line-frequency applications.
• Clear electrical markers — Defined tan δ (0.15 at 20 °C, 120 Hz) and a stated leakage current (1230 µA) enable straightforward design margining and validation.
• Robust mechanical form factor — Snap-in radial can (φ30×40 mm) simplifies board mounting and secures the capacitor in high-vibration or industrial environments.
• Production-ready packaging — Tray packing supports automated assembly and efficient handling for volume manufacturing.
• RoHS compliant — Meets environmental substance requirements for regions that require RoHS conformity.
