LGY1H682MELB35

The LGY1H682MELB35 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGY series designed for long-life, high-reliability power applications. It provides 6.8 mF (6800 μF) capacitance at a 50 V rating in a radial, can-style snap-in package and is RoHS compliant.

Engineered for industrial power supplies and ballast use, this capacitor delivers extended endurance at elevated temperature and dependable ripple handling where sustained performance is required.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 μF) rated at 50 V for bulk energy storage and smoothing in power rails.
• Long-Life Endurance — Specified to withstand 5000 hours of D.C. bias plus rated ripple current at 105°C with capacitance change within ±25% after test.
• Operating Temperature Range — Designed for −40°C to +105°C operation to cover demanding industrial environments.
• High Ripple Capability — Rated ripple current of 2.5 A at 120 Hz and 2.875 A at 50 kHz; frequency coefficients provided in the datasheet allow designers to scale ripple ratings with frequency.
• Low-Temperature Stability — Datasheet impedance ratios: Z(−25°C)/Z(+20°C) ≤ 4 and Z(−40°C)/Z(+20°C) ≤ 20 for the 16–100 V range, aiding performance predictions in cold conditions.
• Leakage Current Specification — Leakage current defined by I ≤ 3√CV (μA) after 5 minutes at 20°C, for predictable standby losses.
• Mechanical & Mounting — Snap-in terminal, radial can package for secure board retention in power assemblies; size L: 3.5 × D: 3 cm and polar construction.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy storage for DC output rails where extended high-temperature life is required.
• Ballast Circuits — Designed specifically for ballast applications requiring reliable operation under sustained ripple and elevated temperatures.
• General-Purpose Power Filtering — Suitable for decoupling, filtering and hold-up in high-reliability power assemblies.

Unique Advantages

• Extended High-Temperature Life — 5000-hour endurance at 105°C reduces replacement frequency in demanding applications.
• Predictable Ripple Performance — Published ripple current ratings at multiple frequencies and frequency coefficients help size capacitors to real-world operating conditions.
• Robust Low-Temperature Behavior — Specified impedance ratios enable designers to account for increased impedance at cold starts.
• Snap-In Mechanical Reliability — Snap-in terminals provide secure board mounting for high-vibration or power-dense assemblies.
• Clear Electrical Limits — Leakage current and endurance pass/fail criteria are defined, supporting deterministic reliability analysis.
• Regulatory Compliance — RoHS conformity supports environmental and regulatory requirements for assemblies.
