LGY1V183MELC40

The LGY1V183MELC40 is an aluminum electrolytic capacitor in a snap-in terminal can designed for long-life, high-temperature operation. It provides a large 18,000 μF capacitance at a 35 V rating with polarized construction and tray packing for production handling.

Engineered for applications where sustained ripple current and elevated-temperature endurance matter, this part is suited for industrial power supplies, ballast applications and general-purpose power filtering. Key value comes from 105°C long-life assurance and measurable ripple current capability for demanding power environments.

Key Features

• Capacitance & Voltage — 18,000 μF rated capacitance at 35 V with ±20% tolerance for bulk energy storage and smoothing.
• High-temperature long life — Rated to operate from −40°C to +105°C with life/endurance specified as 5000 hours at 105°C; after this test, capacitance change is within ±25% and leakage current remains at or below initial specification.
• Ripple current capability — Rated ripple current of 3.5 A at 120 Hz (low frequency) and 4.025 A at 50 kHz (high frequency) to support heavy AC ripple environments.
• Leakage current — Product-specified leakage current of 2,380 μA; the series datasheet also indicates the standard leakage test condition I ≤ 3√CV (μA) after 5 minutes at 20°C.
• Mounting & package — Snap-in terminal, radial can (snap-in) style for secure board mounting; supplied in tray packing for assembly readiness.
• RoHS compliance — Compliant with RoHS requirements.
• Compact form factor — Body dimension reported as φ35 × 40L (L: 4 × D: 3.5 cm), providing high capacitance in a compact footprint.

Typical Applications

• Industrial power supplies — Bulk smoothing and energy storage in high-reliability power converters where long life at elevated temperature is required.
• Ballasts — Designed for use in ballast circuits as noted in the series documentation, providing stable capacitance and ripple handling under thermal stress.
• General-purpose power filtering — Bulk filtering and decoupling in systems that benefit from large capacitance and robust ripple current ratings.

Unique Advantages

• Long-life assurance: 5000 hours rated endurance at 105°C with defined limits on capacitance change and leakage current for predictable aging behavior.
• High ripple tolerance: Specified ripple currents at both low and high frequencies support designs exposed to substantial AC stress.
• Large capacitance in compact can: 18,000 μF in a φ35 × 40L package enables space-efficient bulk energy storage.
• Secure snap-in mounting: Snap-in terminal and radial can format simplify assembly and provide a robust mechanical connection to the PCB.
• Production-friendly packaging: Tray packing supports handling and placement during manufacturing.
• Standards-based leakage characterization: Leakage behavior aligns with the datasheet test condition I ≤ 3√CV (μA) after 5 minutes at 20°C, supporting predictable specification comparison.
