LGY1E103MELA35

The LGY1E103MELA35 is an aluminum electrolytic capacitor in a snap-in terminal can designed for long-life operation at elevated temperatures. It provides 10 mF capacitance at a 25 V rating and is intended for industrial power supplies and ballast applications where reliable ripple-current handling and long-term endurance are required.

Built for continuous operation across a wide temperature range (–40°C to +105°C) and qualified for 5000 hours of ripple-current endurance at 105°C, this snap-in radial can supports designs that demand stable performance under sustained thermal and electrical stress.

Key Features

• Capacitance & Voltage — 10 mF rated capacitance with a 25 V rated voltage, suitable for bulk energy storage and filtering in power electronics.
• High-temperature long life — Endurance specified as 5000 hours at 105°C when D.C. bias plus rated ripple current is applied; designed to retain capacitance within ±25% after the endurance test.
• Snap-in terminal package — Radial, can-type snap-in mounting for secure PCB installation in power supply and ballast layouts.
• Ripple current capability — Rated ripple current of 2.3 A at 120 Hz and 2.645 A at 50 kHz, providing effective AC-current handling for switching and AC-fed supplies.
• Wide operating temperature — Specified operating range of –40°C to +105°C for use across typical industrial environments.
• Polarized design & tolerance — Polarized capacitor with capacitance tolerance of ±20% (–20% to +20%).
• Leakage current specification — Leakage current defined by I ≤ 3√(C·V) μA after 5 minutes at 20°C, enabling predictable leakage behavior for design calculations.
• Electrical loss (tan δ) — Maximum tan δ of 0.40 at the 25 V rating (measurement at 120 Hz, 20°C), supporting predictable ESR-related behavior.
• RoHS compliant — Conforms to RoHS directive requirements stated in the product description.

Typical Applications

• Industrial power supplies — Bulk filtering and energy storage where long-term ripple endurance at elevated temperature is required.
• Ballast circuits — Designed for ballast applications specified in the product description, providing dependable performance under sustained ripple stress.
• AC-fed and switching converters — Provides ripple-current handling (2.3 A at 120 Hz, 2.645 A at 50 kHz) for smoothing and transient support in converter output stages.

Unique Advantages

• Long-duration high-temperature reliability — 5000-hour endurance at 105°C gives designers quantifiable lifetime performance for demanding industrial applications.
• Measured ripple-current ratings — Specified ripple current values at both low and high frequencies let engineers size thermal and cooling requirements accurately.
• Predictable aging and end-of-life behavior — Endurance limits (capacitance within ±25%, tan δ ≤ 250% of initial, leakage ≤ initial) provide clear criteria for maintenance and replacement planning.
• Secure snap-in mounting — Radial snap-in terminals simplify mechanical retention in power-dense PCBs while supporting robust electrical connections.
• Clear electrical specifications — Leakage current formula and tan δ limits at rated conditions allow deterministic modeling in system simulations.
• Regulatory compliance — RoHS compliance supports use in regulated commercial and industrial products.
