Overview of LGU1H392MELB – Aluminum Electrolytic Capacitor, Snap-In, 50 V, 3900 µF, 105°C
The LGU1H392MELB is an aluminum electrolytic capacitor in a snap-in terminal can, offering 3.9 mF capacitance at 50 V with ±20% tolerance. Designed for general-purpose applications, it provides high-capacitance energy storage in a compact φ30 × 25 mm package and is supplied in tray packing for production use.
Key value comes from its 105°C endurance and rated ripple-current capability — the part is specified to withstand 3000 hours of rated ripple current at 105°C — and it is RoHS-compliant for regulated environments.
Key Features
- Capacitance & Voltage: 3.9 mF (3900 µF) at a rated voltage of 50 V with ±20% tolerance, suitable where significant bulk capacitance is required.
- High-temperature Endurance: Operating temperature range –40 °C to 105 °C with an endurance rating of 3000 hours at 105 °C under D.C. bias plus rated ripple current.
- Rated Ripple Current: Specified ripple current of 2.22 A at 120 Hz and 2.553 A at 50 kHz, with frequency coefficients defined in the series datasheet for higher frequencies.
- Snap-in Mounting & Package: Radial, can-type snap-in terminals in a φ30 × 25 mm (L: 2.5 cm × D: 3.0 cm) package for board-level installation; tray packing for production handling.
- Electrical Loss and Leakage: Specified tan δ and leakage current limits per the LGU series (tan δ max. 0.30 at 50 V, measured at 120 Hz, 20 °C; leakage current I ≤ 3 CV (µA) after 5 minutes at 20 °C).
- Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).
- Polarized Design: Polar electrolytic capacitor for DC circuit use.
Typical Applications
- General-purpose power systems: Use where 3.9 mF at 50 V and high-temperature endurance are required for bulk capacitance and energy storage.
- Industrial and commercial assemblies: Snap-in terminal design and tray packing support board-level mounting and production assembly in general-purpose equipment.
- High-ripple environments: Applied where sustained ripple-current capability at elevated temperature (3000 hours at 105 °C) is needed to meet reliability targets.
Unique Advantages
- Long-duration ripple endurance: Specified to withstand 3000 hours of rated ripple current at 105 °C, supporting designs requiring sustained high-temperature operation.
- High capacitance in a compact can: 3900 µF delivered in a φ30 × 25 mm package provides substantial capacitance without a large board footprint.
- Frequency-aware ripple specification: Published ripple current values at 120 Hz and 50 kHz, with frequency coefficients in the series datasheet to evaluate performance across frequencies.
- Clear electrical limits: Defined tan δ and leakage current criteria (including I ≤ 3CV after 5 minutes) permit predictable selection and qualification in designs.
- Regulatory compliance: RoHS conformity for use in regions requiring restricted substance compliance.
Why Choose LGU1H392MELB?
LGU1H392MELB positions itself as a reliable, general-purpose aluminum electrolytic solution where high capacitance, 50 V rating, and elevated-temperature endurance are required. The combination of 3900 µF capacitance, snap-in mounting, and specified ripple-current endurance at 105 °C makes it suitable for production assemblies that demand predictable long-term performance.
It is a practical choice for engineers and procurement teams specifying bulk capacitance with documented electrical limits, temperature range, and RoHS compliance, backed by a datasheet that defines endurance, leakage, and frequency-dependent ripple behavior for design validation.
