LGY1E103MELZ40

The LGY1E103MELZ40 is a snap‑in terminal aluminum electrolytic capacitor rated for 25 V and 10000 µF (±20% tolerance). It is a radial, snap‑in can designed for general‑purpose power applications that require high ripple handling and long life at elevated temperature.

Engineered for industrial power supplies and ballast applications, this part combines high ripple current capability and a 5000‑hour endurance at 105°C to deliver dependable performance in sustained high‑temperature environments. The part is RoHS compliant and available in tray packing for mass production.

Key Features

• Capacitance & Tolerance — 10000 µF nominal with ±20% tolerance, suitable for bulk energy storage and smoothing in power rails.
• Rated Voltage — 25 V DC rating for a wide range of low‑voltage power applications.
• High Ripple Current Handling — 2300 mA at 120 Hz (low frequency) and 2645 mA at 50 kHz (high frequency) to support heavy AC ripple and switching environments.
• Long Life Endurance — Designed for 5000 hours at 105°C under rated ripple and DC bias, meeting the series’ long‑life assurance criteria.
• Temperature Range — Operating range from −40°C to +105°C for use across varied thermal conditions.
• Loss Angle (tan δ) — tan δ = 0.40 maximum at 20°C and 120 Hz, providing a specified dissipation characteristic for design calculations.
• Leakage Current — Specified leakage current of up to 1500 µA for assessing standby and quiescent current budgets.
• Package & Mounting — Snap‑in radial can (φ22 × 40 mm) for secure board mounting and mechanical stability in power assemblies.
• Compliance & Production — RoHS compliant and offered in tray packing; part is in mass production.

Typical Applications

• Industrial Power Supplies — Bulk filtering and smoothing where high ripple currents and long thermal endurance are required.
• Ballast Circuits — Designed for ballast application use as indicated in product guidance, providing steady capacitance under sustained ripple stress.
• General‑Purpose Power Filtering — Energy storage and decoupling in industrial equipment and power modules that operate up to 105°C.

Unique Advantages

• Durable high‑temperature performance: 5000 hours endurance at 105°C ensures stable capacitance and controlled tan δ over long operating cycles.
• High ripple capability: Rated ripple currents of 2.3 A (120 Hz) and 2.645 A (50 kHz) reduce heating and improve reliability in high‑ripple environments.
• Compact snap‑in package: φ22 × 40 mm radial can with snap‑in terminals provides robust mechanical retention for production assemblies.
• Clear electrical parameters: Specified leakage current (1500 µA) and tan δ (0.40 at 120 Hz, 20°C) make it straightforward to model losses and standby currents.
• RoHS compliant and production ready: Tray packing and mass production status simplify procurement and assembly planning for volume builds.
