LGY1K332MELB35

The LGY1K332MELB35 is an aluminum electrolytic, snap-in terminal capacitor from Nichicon’s LGY series designed for long-life, high-reliability power applications. It delivers 3.3 mF of polarized capacitance at an 80 V rating in a radial, snap‑in can package optimized for industrial power supplies and ballast applications.

Key value propositions include long-life endurance at elevated temperature (5000 hours at 105°C), robust ripple-current handling across frequency, and RoHS compliance for regulatory compatibility.

Key Features

• Capacitance & Voltage: 3.3 mF nominal capacitance rated for 80 V, providing substantial bulk energy storage for power supply filtering and decoupling.
• Long-life Endurance: Designed to withstand 5000 hours of ripple-current application at 105°C, supporting dependable performance in high-temperature environments.
• High Ripple Current Capability: Rated ripple current of 2.4 A at 120 Hz and 2.76 A at 50 kHz, with frequency coefficients (series data) that increase allowable ripple at higher frequencies up to 1.15× above 1 kHz.
• Operating Temperature Range: Specified for –40°C to +105°C to cover a wide range of industrial ambient conditions.
• Package & Mounting: Radial, snap‑in can with snap‑in terminals for secure board mounting in industrial assemblies.
• Polarized Construction & Tolerance: Polarized aluminum electrolytic with capacitance tolerance of ±20% (–20% to +20%).
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).
• Compact Dimensions: Physical footprint listed as L: 3.5 × D: 3 cm for space-conscious power designs.

Typical Applications

• Industrial Power Supplies: Bulk filtering and energy storage where sustained ripple handling and elevated-temperature endurance are required.
• Ballast Systems: Specified for ballast applications where long-life performance at high temperature supports reliable operation.
• General-Purpose Power Filtering: Suitable for general-purpose industrial electronics that need polarized bulk capacitance and robust ripple capacity.

Unique Advantages

• Long-life reliability: 5000 hours endurance at 105°C reduces replacement frequency and supports continuous operation in demanding environments.
• Broad ripple-frequency performance: Measured ripple currents at both 120 Hz and 50 kHz, plus frequency coefficients that increase allowable ripple at higher frequencies, help designers manage thermal stress across switching and line-frequency domains.
• Wide operating range: –40°C to +105°C rating enables deployment across a wide span of industrial ambient conditions.
• Secure snap‑in mounting: Radial snap‑in terminals provide mechanical stability for high-vibration or high-current board assemblies.
• Regulatory readiness: RoHS compliance simplifies regulatory tracking and materials selection for environmentally constrained programs.
• Compact form factor: Small can dimensions (L: 3.5 × D: 3 cm) for space-efficient power module design.
