LGY1K182MELB25

The LGY1K182MELB25 is a snap‑in terminal aluminum electrolytic capacitor designed for long‑life operation in industrial power environments. It combines a high capacitance of 1.8 mF with an 80 V rating and a radial snap‑in can package to provide robust bulk energy storage and ripple handling.

Engineered for demanding applications, this capacitor is specified for operation from −40°C to +105°C with a long‑life assurance of 5000 hours under rated ripple current at 105°C. It is RoHS compliant and intended for use where reliability and predictable endurance are required, such as industrial power supplies and ballast circuits.

Key Features

• Snap‑in Termination & Package Radial, can‑style snap‑in package provides secure mechanical retention for applications requiring through‑hole snap mounting.
• Capacitance & Voltage Rated capacitance 1.8 mF with an 80 V working voltage and a capacitance tolerance of −20% to +20%.
• Wide Operating Temperature Specified for use from −40°C to +105°C to support a broad range of industrial environments.
• Long‑Life Endurance Endurance specified as 5000 hours at 105°C with D.C. bias plus rated ripple current applied; capacitance change, dissipation factor, and leakage limits are defined for reliable long‑term performance.
• Ripple Current Capability Rated ripple current of 1.8 A at 120 Hz and 2.07 A at 50 kHz to support smoothing and filtering in power electronics.
• Leakage Current Specification Leakage current limited by the datasheet formula I ≤ 3√(C·V) μA after 5 minutes at 20°C, enabling predictable standby losses.
• Dissipation Factor (tan δ) Specified tan δ limits at 120 Hz and 20°C (for 80 V the maximum tan δ is 0.20), supporting evaluation of ESR and thermal behavior.
• RoHS Compliance Compliant with the RoHS directive (2011/65/EU, (EU)2015/863) for lead‑free assembly requirements.

Typical Applications

• Industrial Power Supplies Bulk energy storage and ripple smoothing where long‑term reliability at elevated temperature is required.
