LGY1C273MELA50

The LGY1C273MELA50 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGY series, providing 27,000 µF capacitance at 16 V with polarized radial can packaging. It is designed for general‑purpose industrial power applications that require high bulk capacitance and dependable long‑life performance.

Key value propositions include long life assurance at elevated temperature (5,000 hours at 105°C), substantial rated ripple current for power filtering, and RoHS compliance for regulatory alignment.

Key Features

• Capacitance & Voltage: 27,000 µF (27 mF) rated at 16 V with ±20% tolerance, providing large bulk energy storage for smoothing and decoupling.
• High‑temperature Long Life: Engineered for 5,000 hours operation at 105°C, enabling sustained performance in hot operating environments.
• Rated Ripple Current: Handles up to 3.6 A at low frequency (120 Hz) and 4.14 A at high frequency (50 kHz), supporting demanding ripple conditions in power supplies.
• Loss and Leakage: Specified tangent of loss angle (tanδ) of 0.50 and measured leakage current of 1.97 mA, allowing predictable electrical behavior for design calculations.
• Mounting & Package: Snap‑in terminal (radial can, snap‑in) for secure board mounting and robust mechanical retention; supplied in tray packing for production handling.
• Operating Range & Compliance: Operates from −40°C to +105°C and is RoHS compliant, aligning with environmental requirements.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and ripple absorption where sustained high temperature endurance and large capacitance are required.
• Ballast Applications: Suitable for ballast circuits as indicated in the LGY series documentation, providing stable capacitance under ripple stress.
• General‑Purpose Power Filtering: Use in general industrial equipment for energy storage, decoupling, and voltage stabilization under continuous operation.

Unique Advantages

• Long high‑temperature life: 5,000 hours at 105°C reduces the need for frequent replacements in high‑heat installations.
• High bulk capacitance in a compact can: 27,000 µF in a φ25 × 50 mm package provides substantial storage in a space‑conscious form factor.
• Robust ripple handling: Rated ripple currents of 3.6 A (120 Hz) and 4.14 A (50 kHz) support heavy AC ripple environments common in power electronics.
• Snap‑in retention: Snap‑in terminal and radial can construction deliver secure mechanical mounting for industrial PCBs.
• Production‑friendly packaging: Tray packing facilitates efficient handling and assembly in production workflows.
• RoHS compliant: Meets RoHS directive requirements for environmental compliance.
