LGU2Z122MELA

The LGU2Z122MELA is an aluminum electrolytic capacitor in a snap‑in terminal (radial can) package designed for general-purpose applications. It delivers 1.2 mF capacitance at a 180 V rating with polarized construction and a ±20% tolerance.

Engineered for elevated-temperature operation, this capacitor is specified for an operating range of −40 °C to 105 °C and is rated to withstand 3,000 hours of applied rated ripple current at 105 °C, providing reliable performance where sustained ripple endurance is required. The product is RoHS compliant.

Key Features

• Electrical Performance  1.2 mF capacitance with a rated voltage of 180 V and a tolerance of −20% to +20% for bulk filtering and energy storage.
• Ripple Current Capability  Rated ripple current of 2.55 A at 120 Hz and 3.825 A at 50 kHz; designed to withstand rated ripple current application for 3,000 hours at 105 °C (endurance condition).
• High‑Temperature Operation  Specified for continuous operation from −40 °C up to 105 °C with endurance validated at the upper temperature for long-term applications.
• Mounting & Package  Snap‑in terminal type in a radial can package for secure PCB mounting and mechanical stability in through‑hole designs.
• Reliability Characteristics  Endurance criteria: after 3,000 hours at 105 °C under DC bias plus rated ripple current, capacitance change remains within ±20% and leakage/tan δ meet specified limits per the LGU series.
• Compliance  RoHS‑compliant according to the provided directive references.
• Form Factor  Physical size approximately L: 5 × D: 2.5 cm, polarized construction for correct polarity installation.

Typical Applications

• General‑purpose power filtering  Bulk smoothing and decoupling in circuits where a 180 V rated, high‑capacitance polarized capacitor is required.
• Industrial power equipment  Use where sustained ripple current and elevated ambient temperature operation (up to 105 °C) are expected.
• Energy storage / bulk capacitance  Bulk energy buffering in circuits designed for general-purpose use with snap‑in mechanical retention.

Unique Advantages

• Proven high‑temperature endurance: Withstands 3,000 hours of rated ripple current application at 105 °C, supporting long-term performance in hot environments.
• Rated for higher DC voltage: 180 V rating enables use in higher-voltage general-purpose power circuits without overrating the component.
• Frequency-adapted ripple handling: Explicit ripple current ratings at 120 Hz and 50 kHz provide clear guidance for both low‑ and high‑frequency ripple conditions.
• Secure PCB mounting: Snap‑in radial can design offers mechanical stability for through‑hole assemblies.
• Regulatory compliance: RoHS compliance supports use in assemblies requiring restricted‑substance conformance.

Why Choose LGU2Z122MELA?

LGU2Z122MELA combines a high voltage rating (180 V), substantial capacitance (1.2 mF), and verified long-term ripple endurance at elevated temperature (3,000 hours at 105 °C) in a snap‑in radial can package. These characteristics make it well suited for designers specifying reliable, polarized aluminum electrolytic bulk capacitance for general-purpose power circuits where elevated temperature and sustained ripple are design considerations.

Its clear electrical and mechanical specifications—ripple current ratings at common frequencies, polarized construction, and RoHS compliance—simplify component selection for procurement and engineering teams focused on durability and predictable field performance.
