LGU2Z122MELC

The LGU2Z122MELC is a snap-in terminal aluminum electrolytic capacitor optimized for general-purpose power applications. It provides 1.2 mF capacitance at a 180 V rating in a compact φ35×30 mm can with snap-in mounting for robust board installation.

Designed for demanding thermal and ripple environments, this capacitor offers a 105 °C category temperature range, 3000‑hour endurance at 105 °C under rated ripple current, and high low- and high-frequency ripple current capability—making it suitable for systems that require durable bulk capacitance and reliable smoothing performance.

Key Features

• Core Electricals 1.2 mF capacitance with ±20% tolerance and a 180 V rated voltage suitable for high-voltage DC applications.
• High-Temperature Endurance Rated for continuous operation up to 105 °C with a specified lifetime of 3000 hours at 105 °C when subjected to rated ripple current.
• Low Loss Characteristic tan δ (DF) specified at 0.15 (max.) at 20 °C and 120 Hz for the applicable voltage range, supporting stable AC performance.
• Leakage Current Specified leakage current of 1390 µA (measured after standard voltage application conditions), suitable for assessing standby and quiescent characteristics.
• Ripple Current Capability 2.55 A rated ripple current at 120 Hz and 3.825 A at 50 kHz, enabling effective filtering and energy buffering across low and high frequencies.
• Mechanical & Mounting Snap-in radial can package (φ35×30 mm) for secure PCB mounting; supplied in tray packaging and listed as mass production status.
• Environmental Compliance RoHS compliant as specified in the product data.

Typical Applications

• General-purpose power filtering Use where 180 V rated bulk capacitance and high ripple current handling are required for smoothing and decoupling.
• Energy buffering in DC systems Applicable to designs that need stored charge at elevated temperatures, leveraging the 1.2 mF capacitance and 105 °C endurance.
• High-frequency ripple mitigation Suitable for circuits requiring significant ripple attenuation at both low (120 Hz) and higher frequencies (tens of kHz), based on the specified ripple current ratings.

Unique Advantages

• High-voltage, high-capacitance combination: 180 V rating paired with 1200 µF supports higher-voltage DC link and bulk energy storage in a single component.
• Proven thermal endurance: 3000 hours at 105 °C under rated ripple current provides a measurable reliability baseline for thermal-stressed designs.
• Dual-frequency ripple performance: Defined ripple current values at 120 Hz and 50 kHz let designers quantify performance across common power system frequencies.
• Compact snap-in package: φ35×30 mm snap-in can offers a space-efficient, mechanically secure solution for through-hole PCB assembly.
• Measured electrical loss and leakage: Specified tan δ and leakage current figures allow precise electrical budgeting for ESR/DF and standby current calculations.
• Regulatory alignment: RoHS compliance supports use in regions and products requiring restricted-substance conformance.
