LGY1H682MELA45

The LGY1H682MELA45 is a Nichicon LGY series aluminum electrolytic capacitor: a 6.8 mF (6800 µF), 50 V, snap‑in terminal radial can designed for long life and dependable performance. It combines large capacitance in a compact φ25 × 45 mm can with robust ripple handling and a −40 °C to 105 °C operating range.

Optimized for industrial power supplies, ballast circuits and general‑purpose power filtering, this part offers 5000 hours endurance at 105 °C and is supplied in tray packing for production use. The device is RoHS compliant and in mass production.

Key Features

• Capacitance & Voltage — 6800 µF nominal capacitance with a 50 V rated voltage and a tolerance of −20% to +20%.
• Snap‑in Radial Can Package — Snap‑in terminal design for secure board mounting in a φ25 × 45 mm (D × L) can; supplied in tray packing for assembly efficiency.
• Long Life Endurance — Rated for 5000 hours at 105 °C under specified ripple, supporting sustained operation in high‑temperature environments.
• Ripple Current Performance — Low‑frequency ripple current 2.5 A (120 Hz) and high‑frequency ripple current 2.875 A (50 kHz), enabling effective smoothing in power circuits across a range of frequencies.
• Leakage and Loss Characteristics — Specified leakage current of 1740 µA and tan δ (loss tangent) of 0.30 measured at 20 °C and 120 Hz, providing clear electrical performance parameters for design validation.
• Wide Operating Temperature — Operational from −40 °C to 105 °C to suit industrial temperature profiles.
• Regulatory Compliance — RoHS compliant for environmental regulatory alignment.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing for switch‑mode power supplies where long life and high ripple capability are required.
• Ballast Circuits — Designed for ballast applications called out in the LGY series specifications, providing stable capacitance and endurance under continuous ripple stress.
• General‑Purpose Power Filtering — Large capacitance and specified leakage/tan δ figures make this capacitor suitable for general DC filtering and decoupling in industrial and commercial equipment.

Unique Advantages

• Proven Long‑life Performance: 5000 hours endurance at 105 °C gives predictable aging characteristics for designs requiring extended operation at elevated temperatures.
• High Ripple Handling: Defined ripple ratings at both 120 Hz (2.5 A) and 50 kHz (2.875 A) let designers account for low‑ and high‑frequency stress in power circuits.
• High Capacitance Density: 6800 µF in a compact φ25 × 45 mm can delivers substantial energy storage while conserving board space.
• Clear Electrical Specifications: Specified leakage current (1740 µA), tan δ (0.30 at 20 °C, 120 Hz) and tolerance (±20%) simplify performance prediction and validation.
• Manufacturing‑Ready Packaging: Tray packing and mass production status support volume assembly and supply chain consistency.
• Environmental Compliance: RoHS compliance supports deployments where restricted substances requirements apply.
