LGY1C393MELC40

The LGY1C393MELC40 is a snap‑in terminal aluminum electrolytic capacitor designed for high‑reliability power applications. It delivers 39,000 µF capacitance at a 16 V rating in a radial, can-style snap‑in package optimized for robust mounting.

Engineered for industrial power supplies and ballast applications, this capacitor emphasizes long life and dependable ripple handling: it is specified to withstand 5000 hours of rated ripple current at 105°C and is compliant with RoHS (2011/65/EU, (EU)2015/863).

Key Features

• High Capacitance: 39,000 µF (39 mF) nominal capacitance for bulk energy storage and smoothing in low‑voltage power rails.
• Rated Voltage: 16 V DC rating suitable for common industrial DC bus and power‑supply designs.
• Long Life Assurance: Endurance specified as 5000 hours at 105°C with D.C. bias plus rated ripple current, supporting extended operation under elevated temperature and ripple stress.
• Wide Operating Temperature: −40°C to +105°C operating range for stable performance across industrial environments.
• High Ripple Capability: Rated ripple current of 4.3 A at 120 Hz and 4.945 A at 50 kHz to support heavy AC ripple and switching power stages.
• Mounting and Package: Snap‑in terminal, radial can package for secure chassis or PCB mounting where mechanical stability is required.
• Low Leakage Specification: Leakage current defined as I ≤ 3√(C·V) µA after 5 minutes at 20°C, enabling predictable standby and bias behavior.
• RoHS Compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing for DC rails in industrial converters and power modules where sustained ripple handling and long life are required.
• Ballasts: Designed for ballast applications requiring high capacitance and reliable ripple endurance at elevated temperatures.
• General‑Purpose Power Filtering: Filtering and decoupling in general‑purpose electronic equipment that benefits from large capacitance and robust mounting.

Unique Advantages

• Extended High‑Temperature Endurance: 5000 hours specified at 105°C under rated ripple current—provides predictable lifetime in hot, ripple‑intensive environments.
• Large Energy Reserve in a Compact Can: 39,000 µF capacitance delivers significant bulk storage for smoothing and hold‑up without requiring parallel arrays of smaller capacitors.
• Demonstrated Ripple Performance: Rated ripple currents of 4.3 A (120 Hz) and 4.945 A (50 kHz) support both low‑frequency and high‑frequency power stages.
• Robust Mechanical Mounting: Snap‑in terminal and radial can package simplify installation and provide secure mechanical retention for chassis or PCB integration.
• Predictable Leakage Behavior: Leakage current limit defined by I ≤ 3√(C·V) µA ensures controllable standby current for system power budgeting.
• Compliance and Reliability: RoHS compliance plus series specifications for low‑temperature impedance stability and tan δ limits deliver verifiable performance across conditions.
