LGY1K182MELA30

The LGY1K182MELA30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGY series. It provides 1.8 mF (1800 µF) capacitance at an 80 V rating in a radial, can-style snap‑in package designed for general-purpose and industrial power applications.

Engineered for high-temperature, long-life operation, this capacitor is specified for operation from −40 °C to 105 °C and is rated for 5,000 hours of ripple-current endurance at 105 °C, making it well suited to power supply smoothing, energy storage, and ballast applications where durability and reliable ripple handling are required.

Key Features

• Capacitance and Tolerance — 1.8 mF (1800 µF) nominal capacitance with ±20% tolerance at 120 Hz, 20 °C for predictable bulk energy storage and smoothing.
• Voltage Rating — 80 V rated voltage for higher‑voltage power rails and applications requiring additional voltage headroom.
• High‑Temperature Long Life — Rated for continuous use from −40 °C to 105 °C with an endurance specification of 5,000 hours at 105 °C under rated ripple current.
• Snap‑in Radial Can Package — Snap‑in terminal construction for robust PCB mounting in radial can format designed for easy insertion and mechanical stability.
• Ripple Current Capability — Specified ripple current of 1.8 A at 120 Hz and 2.07 A at 50 kHz to support high‑ripple power supply conditions.
• Polarized Electrolytic — Polarized design for DC filtering and bulk decoupling applications.
• RoHS Compliant — Conforms to RoHS directive for use in assemblies requiring restricted substances compliance.
• Compact Footprint — Physical size approximately L: 3 × D: 2.5 cm to balance capacitance with space considerations on the PCB.

Typical Applications

• Industrial Power Supplies — Bulk filtering and energy storage on higher‑voltage rails where the 80 V rating and 105 °C long‑life specification support sustained ripple loading.
• Ballasts — Designed for ballast circuits that require robust ripple handling and long operational life at elevated temperatures.
• General‑Purpose Electronics — DC filtering, smoothing, and decoupling in equipment that benefits from a snap‑in radial can and polarized electrolytic characteristics.

Unique Advantages

• Long operational life: 5,000 hours at 105 °C under rated ripple current provides predictable longevity for industrial and continuous‑duty applications.
• High voltage capability: 80 V rating gives designers headroom for higher‑voltage rails without overrating multiple lower‑voltage parts.
• Effective ripple management: Published ripple current values at 120 Hz and 50 kHz quantify the capacitor’s ability to handle AC stress in real circuits.
• Easy PCB integration: Snap‑in terminal radial can package offers mechanical stability and straightforward mounting for through‑hole assembly.
• RoHS compliance: Meets restricted‑substances requirements for regulated markets and assemblies.
