LGY1K332MELC30

The LGY1K332MELC30 is an aluminum electrolytic capacitor in Nichicon's LGY long‑life snap‑in series. It combines a 3.3 mF capacitance with an 80 V rated voltage and snap‑in terminal mounting for secure installation in power assemblies.

Designed for industrial power supplies and ballast applications, this part delivers long operating life—specified for 5000 hours under rated ripple current at 105°C—making it suitable where dependable performance and thermal endurance are required. The component is RoHS compliant.

Key Features

• Capacitance & Voltage — 3.3 mF capacitance with an 80 V rated voltage for energy storage and smoothing in higher‑voltage power circuits.
• Snap‑in Package — Radial can with snap‑in terminals for reliable board retention and ease of installation in power modules and assemblies.
• Long‑life Endurance — Specified to withstand 5000 hours of D.C. bias plus rated ripple current at 105°C; after this test, capacitance change remains within ±25%, tan δ is ≤250% of initial, and leakage current is ≤ initial specified value.
• Operating Temperature Range — Rated for −40°C to 105°C to cover a wide range of industrial operating conditions.
• Ripple Current Capability — Rated ripple current of 2.4 A at 120 Hz and 2.76 A at 50 kHz to handle power supply ripple; frequency coefficients in the LGY series increase allowable ripple at higher frequencies.
• Tolerance & Polarization — Polarized capacitor with capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Compact Footprint — Physical size L: 3 × D: 3.5 cm for space‑conscious power designs.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Used for bulk storage and smoothing in high‑reliability power supply rails where elevated temperature endurance and rated ripple handling are required.
• Ballast Applications — Suited to ballast circuits that require robust capacitors capable of withstanding continuous ripple and elevated operating temperatures.
• General Purpose Power Filtering — Applicable where a polarized, high‑capacitance, high‑voltage snap‑in capacitor is needed for energy buffering and ripple reduction.

Unique Advantages

• Validated Long Life: Endurance specified for 5000 hours at 105°C under rated ripple current ensures predictable performance in long‑duty industrial applications.
• High Ripple Handling: Measured ripple current ratings (2.4 A at 120 Hz, 2.76 A at 50 kHz) combined with series frequency coefficients support demanding ripple conditions.
• Wide Temperature Range: −40°C to 105°C rating provides thermal headroom for elevated‑temperature environments.
• Secure Snap‑in Mounting: Radial can with snap‑in terminals delivers reliable mechanical retention for power assemblies and simplifies PCB placement.
• Clear Electrical Specs: 3.3 mF capacitance, 80 V rating, and ±20% tolerance allow straightforward selection and replacement in designs specified to these parameters.
• Regulatory Compliance: RoHS compliance supports use in regions requiring restriction of hazardous substances.
