LGY1C153MELB30

The LGY1C153MELB30 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGY Long Life Assurance series. It provides 15,000 µF capacitance at a 16 V rating and is designed for demanding thermal and ripple environments.

Engineered for industrial power applications, this radial can (snap‑in) capacitor is suited for industrial power supplies and ballast applications where long endurance under ripple current and wide operating temperature are required. The part is RoHS compliant.

Key Features

• Nominal Capacitance & Voltage — 15,000 µF (15 mF) at 16 V, providing substantial bulk energy storage for low‑voltage power rails and smoothing.
• Long Life Endurance — Designed to withstand 5,000 hours of DC bias plus rated ripple current at 105°C; capacitance change remains within ±25% after the endurance test.
• High Temperature Rating — Operating temperature range −40°C to +105°C to support elevated ambient thermal conditions.
• Ripple Current Capability — Rated ripple current of 2.7 A at 120 Hz and 3.105 A at 50 kHz; frequency coefficients are provided in the LGY series data for frequency‑dependent ripple derating.
• Leakage Current Specification — Leakage current specified as I ≤ 3√(C·V) µA after 5 minutes at 20°C (C = µF, V = rated voltage), per the series datasheet.
• Robust Mounting — Snap‑in terminal radial can package for secure chassis or board mounting in power assemblies.
• Tolerance & Polarization — Capacitance tolerance ±20% and polarized construction; observe polarity in applications.
• Environmental Compliance — Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy storage for power rails in industrial converters and supply modules operating at up to 105°C.
• Ballast Circuits — Suited for ballast applications where sustained ripple and elevated temperature endurance are required.
• General Purpose Power Conditioning — Use where large capacitance at low voltage is needed for filtering, hold‑up, or transient suppression in general purpose equipment.

Unique Advantages

• Proven Long‑Life Design — 5,000 hours endurance at 105°C under ripple current ensures predictable aging and performance in hot operating environments.
• High Bulk Capacitance at Low Voltage — 15,000 µF at 16 V delivers substantial energy storage for smoothing and hold‑up without requiring multiple smaller capacitors.
• Clear Ripple Ratings — Specified ripple currents at 120 Hz and 50 kHz allow designers to size capacitors against expected AC stress with available frequency coefficients from the series datasheet.
• Robust Mechanical Mounting — Snap‑in radial can package provides a secure mechanical connection for power modules and chassis installations.
• Wide Temperature Range — −40°C to +105°C operation supports a broad set of industrial environments.
• Regulatory Compliance — RoHS conformity supports use in designs targeting restricted‑substance requirements.
