LGY2A182MELB35

The LGY2A182MELB35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGY series. It is a polarized, radial can snap‑in type designed for long life operation at elevated temperature.

Engineered for industrial power electronics, this part is suited for industrial power supplies and ballast applications where sustained ripple handling and dependable performance are required. Key value comes from its 100 V rating, 1.8 mF capacitance and a long‑life 105°C endurance specification.

Key Features

• Capacitance & Voltage: Rated at 1.8 mF with a 100 V DC rating and capacitance tolerance of ±20%.
• Long‑life 105°C Endurance: Designed to withstand 5000 hours of application of rated ripple current at 105°C (LGY series long life assurance).
• Ripple Current Capability: Rated ripple current of 2 A at 120 Hz and 2.3 A at 50 kHz; series frequency coefficient shows 1.00 at 120 Hz and 1.15 at 10 kHz and above.
• Wide Operating Temperature Range: Specified for operation from −40°C to +105°C.
• Mounting & Package: Snap‑in terminal, radial can snap‑in package for secure board mounting; size L: 3.5 × D: 3 cm with a seated height max of 1.378 inch.
• Polarized Device: Polar capacitor intended for DC power applications.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk filtering and smoothing where 100 V rating and sustained ripple handling at elevated temperature are needed.
• Ballast Circuits: Energy storage and ripple absorption in ballast applications, using the LGY series long‑life specification for reliability.
• General‑Purpose Power Electronics: DC link, reservoir, or decoupling roles in general‑purpose power systems that require polarized snap‑in capacitors.

Unique Advantages

• Proven Long‑Life Performance: 5000 hours endurance at 105°C under rated ripple conditions reduces replacement frequency in high‑temperature installations.
• High Voltage Capability: 100 V rating supports higher‑voltage rails without series stacking.
• Robust Ripple Handling: Specified ripple current values at both low and high frequencies help maintain capacitor stability under real operating loads.
• Temperature Resilience: −40°C to +105°C operating range enables use across a broad set of industrial environments.
• Secure Snap‑in Mounting: Radial snap‑in can package provides reliable mechanical and electrical connection for power assemblies.
• Regulatory Compliance: RoHS compliance supports environmental requirements for commercial and industrial products.
