LGJ2E121MELA15

The LGJ2E121MELA15 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It combines a 120 µF capacitance with a 250 V rating in a low-profile φ25 × 15 mm radial, can-type package suitable for panel- or chassis-mounted power assemblies.

Engineered for robust operation, this part delivers measurable ripple-handling and endurance: 600 mA ripple at 120 Hz, 900 mA at higher frequency (50 kHz), a leakage current of 510 µA, and a 2000-hour endurance at 105 °C, making it appropriate for designs requiring stable performance across a wide temperature range.

Key Features

• Core Type: Snap-in terminal aluminum electrolytic capacitor—radial, can-style package for secure mounting and high-current bus installations.
• Capacitance & Voltage: 120 µF nominal capacitance at a 250 V rated voltage with ±20% tolerance for predictable energy storage and bulk decoupling.
• Ripple Current Performance: 600 mA at 120 Hz (low frequency) and 900 mA at 50 kHz (high frequency), enabling effective smoothing under both line-frequency and higher-frequency ripple conditions.
• Loss Characteristics: Specified dissipation factor (tan δ) of 0.2 measured at 20 °C, 120 Hz, for loss-budgeting and thermal design considerations.
• Leakage Current: Measured leakage current of 510 µA, useful for estimating standby and leakage power in system-level calculations.
• Temperature & Endurance: Rated for −40 °C to 105 °C operation with a 2000-hour life rating at 105 °C to support sustained elevated-temperature deployments.
• Mechanical & Packaging: Compact φ25 × 15 mm low-profile can (L: 15 mm × D: 25 mm) provided in tray packing; part is in mass production for supply continuity.

Typical Applications

• General-purpose power systems: Bulk energy storage and smoothing in power supplies and converters where a 250 V, 120 µF snap-in capacitor is required.
• High-ripple circuits: Circuits exposed to significant ripple currents benefit from the specified 600 mA (120 Hz) and 900 mA (50 kHz) handling capabilities.
• Thermally demanding environments: Systems operating across −40 °C to 105 °C that need a capacitor with a 2000-hour endurance rating at elevated temperature.

Unique Advantages

• High-voltage, compact solution: 250 V rating in a low-profile φ25 × 15 mm package enables space-efficient placement in power assemblies.
• Frequency-flexible ripple handling: Distinct low- and high-frequency ripple current ratings allow designers to size components for both line-frequency smoothing and higher-frequency decoupling.
• Endurance at elevated temperature: 2000-hour life at 105 °C supports reliable operation in elevated-temperature installations and reduces maintenance-driven replacements.
• Predictable leakage and loss metrics: Specified 510 µA leakage and tan δ at 20 °C, 120 Hz provide concrete parameters for thermal and power-loss budgeting.
• Production-ready packaging: Tray packing and mass production status support volume procurement and assembly throughput.
