LGR2W680MELZ40

The LGR2W680MELZ40 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGR Long Life Assurance series. It provides 68 µF capacitance at a 450 V rating in a radial, can-style snap‑in package designed for general‑purpose applications.

Designed for high-temperature, long-life operation, this part is specified for use up to 105°C with a 10000‑hour endurance under rated ripple current, and is RoHS compliant.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance.
• Long‑Life, High‑Temperature — Qualified for 10000 hours of operation at 105°C under DC bias plus rated ripple current as part of the LGR Long Life Assurance series.
• Snap‑in Radial Package — Snap‑in terminal, radial can package (size L: 4 × D: 2.2 cm) for secure board mounting and high current handling.
• Ripple Current Capability — Rated ripple currents of 530 mA at 120 Hz and 757.9 mA at 50 kHz, with frequency‑dependent coefficients defined in the series datasheet.
• Electrical Stability — Endurance specification: capacitance change within ±25% after the 10000‑hour test; tan δ limit for 450 V parts is 0.20 (max.).
• Leakage Current — Leakage current per datasheet: I ≤ 3√(C·V) µA after 5 minutes’ application of rated voltage at 20°C.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Applications — Where a 450 V, 68 µF, high‑temperature, long‑life electrolytic capacitor is required for filtering or energy storage.
• Industrial Electronics — Use in assemblies that demand sustained performance at up to 105°C and long endurance under ripple current stress.
