LGU1V123MELB

The LGU1V123MELB is a snap‑in terminal aluminum electrolytic capacitor offering 12,000 µF capacitance at a 35 V rating. It is designed for general‑purpose applications that require high bulk capacitance and stable performance across a wide temperature range.

Key value comes from its 105°C endurance rating with 3,000 hours of rated ripple current operation, high ripple current capability, and a compact φ30 × 40 mm can with snap‑in mounting for straightforward installation and reliable board retention.

Key Features

• Capacitance & Voltage  12,000 µF nominal capacitance with a rated voltage of 35 V and ±20% tolerance at 120 Hz, 20°C.
• High‑Temperature Endurance  Rated for 3,000 hours at 105°C under rated DC bias plus rated ripple current; meets the LGU series endurance criteria.
• Ripple Current Performance  Low‑frequency ripple current 3.28 A at 120 Hz and high‑frequency ripple current 3.772 A at 50 kHz, supporting applications with continuous ripple stress.
• Electrical Characteristics  Specified tangent of loss angle (tan δ) 0.35 at 35 V (120 Hz, 20°C) and measured leakage current of 1,940 µA (after test conditions stated in product data).
• Robust Operating Range  Rated for operation from −40°C to +105°C to support elevated‑temperature environments within its specification window.
• Package & Mounting  Snap‑in radial can (φ30 × 40 mm) for secure mechanical retention and tray packing for board‑level handling and assembly.
• Regulatory  Compliant with RoHS (2011/65/EU, (EU)2015/863) as noted in the product documentation.

Typical Applications

• General Purpose  Suited for general‑purpose capacitor roles where high bulk capacitance and extended high‑temperature endurance are required.
• Power Supply Support  Appropriate where sustained ripple handling and large capacitance are needed to stabilize DC rails under continuous load.
• Industrial Electronics  Applicable in equipment that operates up to 105°C and requires long life under rated ripple current conditions.

Unique Advantages

• High Bulk Capacitance: 12,000 µF provides substantial energy storage per unit for smoothing and bulk decoupling tasks.
• Rated Endurance at Elevated Temperature: 3,000 hours at 105°C under rated conditions supports long operational life in hot environments.
• Strong Ripple Current Capability: Specified ripple currents at both low and high frequencies help manage thermal and electrical stress from AC components on the DC bus.
• Snap‑in Mounting: Radial snap‑in can option simplifies board installation and improves mechanical stability in through‑hole assemblies.
• RoHS Compliance: Meets RoHS directive requirements, aiding regulatory alignment for assembled products.
