LGU1H472MELA

The LGU1H472MELA from Nichicon is a snap‑in terminal aluminum electrolytic capacitor providing 4700 µF (4.7 mF) capacitance at a 50 V rating with ±20% tolerance. It is a general‑purpose power component designed for applications that require bulk capacitance, high ripple current capability and long endurance at elevated operating temperatures.

Key Features

• Capacitance & Voltage: 4700 µF (4.7 mF) rated at 50 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Snap‑In Radial Can Package: Snap‑in terminal, radial can construction sized φ25 × 35 mm (L). Tray packing and mass production availability simplify assembly and procurement.
• High Ripple Current Capability: Rated ripple current of 2.61 A at 120 Hz (low frequency) and 3.002 A at 50 kHz (high frequency), supporting sustained AC stress on DC rails.
• Low Loss: Tangent of loss angle (tan δ) of 0.30 at 20°C and 120 Hz for the 50 V rating, indicating controlled dissipation under AC conditions.
• Leakage Current: Specified leakage current of 1450 µA (measured per datasheet conditions).
• Extended Endurance at High Temperature: Endurance of 3000 hours at 105°C with rated DC bias plus rated ripple current, meeting the LGU series endurance requirement.
• Wide Operating Temperature Range: Specified for −40°C to +105°C operation.
• RoHS Compliant: Meets RoHS directive requirements as part of Nichicon's LGU series.

Typical Applications

• General‑purpose power systems: Bulk capacitance and ripple handling for general‑purpose power circuits where a 50 V, 4700 µF snap‑in capacitor is required.
• High‑temperature environments: Applications that subject capacitors to elevated temperatures benefit from the LGU1H472MELA's 3000‑hour endurance at 105°C.
• Board‑level assemblies with snap‑in mounts: Snap‑in terminal and radial can package simplify mechanical mounting and large‑value capacitance placement on PCBs.

Unique Advantages

• Designed for sustained ripple stress: High rated ripple currents (2.61 A @120 Hz, 3.002 A @50 kHz) allow the capacitor to handle continuous AC components on DC rails.
• Long life under elevated temperature: 3000 hours endurance at 105°C supports reliable operation in demanding thermal environments.
• Low dielectric loss: tan δ of 0.30 at 20°C/120 Hz helps limit internal heating and power dissipation during AC exposure.
• Clear procurement and assembly attributes: Tray packing and mass production status enable predictable supply and streamlined assembly for volume manufacturing.
• Compact high‑value option: 4700 µF in a φ25 × 35 mm snap‑in can provides substantial capacitance per footprint for space‑constrained designs.
• Regulatory compliance: RoHS compliance supports use in regions and products requiring restricted substances conformance.
