LGU2P331MELZ

The LGU2P331MELZ is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose use. It delivers 330 µF capacitance at 220 V in a φ22 × 35 mm can with a snap-in mounting style optimized for high-volume production and secure PCB installation.

Engineered for elevated-temperature operation, this capacitor is rated to 105°C with a 3000-hour endurance under rated ripple conditions, and offers specified low- and high-frequency ripple current capability for demanding power applications.

Key Features

• Capacitance & Voltage: 330 µF rated capacitance at 220 V for energy storage and smoothing in power circuits.
• High Temperature Endurance: 105°C operating rating with 3000 hours endurance when subjected to rated ripple current and DC bias at 105°C.
• Ripple Current Handling: Rated ripple current of 1.25 A at 120 Hz (low frequency) and 1.875 A at 50 kHz (high frequency) to support both mains-frequency and high-frequency power systems.
• Leakage Current: Specified leakage current of 800 µA to enable predictable leakage behavior after voltage application.
• Package & Mounting: Snap-in terminal, radial can package (φ22 × 35 mm) suitable for robust mechanical retention and tray packing for mass production.
• Operating Temperature Range: −40°C to +105°C to accommodate a wide ambient range in general-purpose systems.
• RoHS Compliant: Constructed in accordance with RoHS requirements for lead-free process compatibility.

Typical Applications

• General-purpose electronic systems: Suitable where a 220 V, 330 µF snap-in electrolytic capacitor is required for bulk capacitance and smoothing.
• Elevated-temperature power modules: Use in designs that must tolerate sustained operation at or near 105°C with specified 3000-hour endurance.
• High-frequency ripple environments: Applicable where higher-frequency ripple currents (up to the specified 1.875 A at 50 kHz) are present and must be managed reliably.

Unique Advantages

• Proven high-temperature endurance: 3000-hour specification at 105°C gives designers measurable long-term performance under sustained thermal stress.
• Dual-frequency ripple capability: Specified ripple current values at both 120 Hz and 50 kHz allow confident selection for mains-frequency and switching-frequency circuits.
• Robust mounting and production readiness: Snap-in terminal and tray packing support reliable PCB retention and streamlined mass-production assembly.
• Predictable leakage behavior: Specified leakage current value aids in system-level power budgeting and startup behavior analysis.
• Wide operating temperature span: −40°C to +105°C supports deployment across varied ambient conditions without exceeding rated limits.
• RoHS compliance: Facilitates integration into lead-free manufacturing flows.
