LGU1E103MELA

The LGU1E103MELA from Nichicon is a snap‑in terminal type aluminum electrolytic capacitor in the LGU series, rated at 25 V with 10000 µF capacitance and ±20% tolerance. It is a general‑purpose capacitor designed for applications that require bulk capacitance, significant ripple handling and extended endurance at elevated temperatures.

Engineered for operation from −40°C to 105°C, the LGU1E103MELA provides 3000 hours of endurance at 105°C under rated ripple conditions, making it suitable for designs that demand stability and long life in high‑temperature environments.

Key Features

• Capacitance & Voltage — 10000 µF (10 mF) capacitance at a rated voltage of 25 V with ±20% tolerance for bulk energy storage and decoupling.
• High‑temperature Endurance — Rated for −40°C to 105°C operating range with 3000 hours lifetime at 105°C when subjected to D.C. bias plus rated ripple current.
• Ripple Current Capability — Supports 2.61 A at 120 Hz (low frequency) and 3.0015 A (listed as 3001.5 mA) at higher frequency, enabling effective handling of sustained ripple currents.
• Loss Angle (tan δ) — Specified tan δ of 0.40 at 20°C and 120 Hz for the 25 V rating, providing a defined dissipation characteristic for design calculations.
• Leakage Current — Listed leakage current of 1500 µA (after 5 minutes’ application of rated voltage at 20°C as per product specification).
• Mechanical & Mounting — Snap‑in radial can package (φ25 × 35L; L: 3.5 × D: 2.5 cm) for secure snap‑in mounting into chassis or PCB fixtures; tray packing for mass production.
• Regulatory — RoHS compliant.

Typical Applications

• General‑purpose electronic equipment — Provides bulk capacitance and smoothing for circuits specified as general purpose.
• High‑temperature assemblies — Suited to designs that must operate reliably up to 105°C with 3000 hours endurance at that temperature under rated ripple conditions.
• High‑ripple current designs — Used where sustained ripple current handling is required, leveraging the specified 2.61 A at 120 Hz and ~3.00 A at higher frequency.
• Secure snap‑in mounting requirements — Snap‑in terminal and radial can package for applications that benefit from robust snap‑in installation and tray packing for production volumes.

Unique Advantages

• Long‑life high‑temperature rating: 3000 hours endurance at 105°C under rated ripple current offers predictable performance over prolonged elevated‑temperature operation.
• Large capacitance in a compact can: 10000 µF in a φ25 × 35 mm profile provides substantial energy storage while minimizing board/chassis footprint.
• Defined ripple performance: Specified ripple currents at both 120 Hz and higher frequency support designs with significant AC stress and enable accurate thermal and reliability planning.
• Snap‑in mounting for production: Radial snap‑in can and tray packing streamline assembly and secure mechanical retention for mass production.
• Clear electrical characteristics: Published tan δ (0.40 at 20°C, 120 Hz) and leakage current figures allow straightforward inclusion in circuit and thermal models.
• RoHS compliance: Meets RoHS requirements for environmental regulatory acceptance.
