LGY1E103MELB30

The LGY1E103MELB30 is a snap‑in terminal aluminum electrolytic capacitor offering 10,000 µF capacitance at a 25 V rating. It is part of Nichicon’s LGY long‑life assurance series designed for demanding industrial power environments.

With a rated operating range of −40°C to 105°C and validated endurance of 5000 hours under rated ripple current at 105°C, this polarized radial can is suited to industrial power supplies, ballast applications and general-purpose power filtering where sustained ripple performance and reliability are important.

Key Features

• High Capacitance: 10,000 µF (10 mF) bulk capacitance for energy storage and smoothing in power systems.
• Rated Voltage: 25 V DC rating suitable for many industrial and power‑supply rails.
• Long‑life Endurance: Designed to withstand 5000 hours application of ripple current at 105°C, maintaining capacitance, tan δ and leakage within specified limits after endurance testing.
• Wide Temperature Range: Specified for operation from −40°C to +105°C to support varied industrial ambient conditions.
• Ripple Current Performance: Rated ripple current of 2.3 A at 120 Hz and 2.645 A at 50 kHz; frequency coefficients provided in the LGY series datasheet allow interpolation across common ripple frequencies.
• Polarized Snap‑in Can Package: Radial, can-style snap‑in mounting for secure PCB retention and high-reliability connections in through‑hole assemblies.
• Leakage and Loss Characteristics: Leakage current specification follows I ≤ 3√(C·V) μA after 5 minutes at 20°C; tan δ maximum for 25 V parts is 0.40 (measured at 120 Hz, 20°C).
• RoHS Compliant: Complies with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk storage and output smoothing where long‑term ripple endurance at elevated temperature is required.
• Ballasts and Lamp Drivers: Energy buffering and filtering in ballast circuits that demand stable performance over long operational periods.
• General‑Purpose Power Filtering: Decoupling and smoothing for industrial control electronics and power conversion modules.

Unique Advantages

• Long thermal endurance: 5000‑hour ripple endurance at 105°C reduces maintenance frequency and supports continuous industrial operation.
• Substantial energy capacity: 10,000 µF provides significant bulk capacitance for smoothing and transient support in power rails.
• Robust mounting: Snap‑in radial can enables secure mechanical retention and reliable through‑hole connections for rugged assemblies.
• Predictable ripple behavior: Published ripple current values and frequency coefficients simplify thermal and ripple budgeting in design.
• Wide ambient tolerance: −40°C to +105°C rating allows deployment across a broad range of industrial environments.
• Regulatory compliance: RoHS conformity supports environmental compliance requirements.
