LGY1K122MELA25

The LGY1K122MELA25 is an aluminum electrolytic capacitor in Nichicon’s LGY series featuring a snap-in terminal configuration. It delivers long-life performance designed for industrial applications where sustained ripple handling and temperature endurance are important.

Typical use cases include industrial power supplies and ballast applications; the component is RoHS compliant and built to withstand prolonged ripple current exposure at elevated temperature.

Key Features

• Capacitance & Tolerance — 1.2 mF capacitance with a tolerance of -20% to 20% for general-purpose filtering and energy storage.
• Rated Voltage — 80 V rated voltage suitable for higher-voltage power supply rails.
• Long-life Endurance — Endurance rating of 5000 hours at 105°C with DC bias plus rated ripple current applied, demonstrating stability under sustained thermal and electrical stress.
• Ripple Current Performance — Rated ripple current of 1.5 A at 120 Hz (low frequency) and 1.725 A at 50 kHz (high frequency); frequency coefficients for the LGY series modify rated ripple across frequency (e.g., 0.88 at 50 Hz, 0.90 at 60 Hz, 1.00 at 120 Hz, up to 1.15 at 10 kHz and above).
• Operating Temperature Range — Specified for -40°C to 105°C operation to cover a wide range of industrial temperature conditions.
• Package & Mounting — Radial can with snap-in terminals for secure PCB mounting; size dimensions L: 2.5 × D: 2.5 cm with a seated height maximum of 2.5 cm.
• Polarized Construction — Polarized electrolytic design for DC power circuits.
• Compliance — Compliant to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies — Bulk filtering and smoothing on higher-voltage rails where long ripple endurance and 105°C operation are required.
• Ballasts and lighting control — Energy storage and ripple handling in ballast circuits as noted for the LGY series.
• General-purpose power conditioning — General DC link and filtering duties in equipment using a polarized aluminum electrolytic with snap-in mounting.

Unique Advantages

• Long operating endurance: 5000 hours at 105°C under rated ripple current improves design reliability for sustained industrial use.
• High voltage capability: 80 V rating supports higher-voltage DC rails without stacking components.
• Robust ripple handling: Specified ripple current at both low and high frequencies, plus frequency coefficients, helps predict thermal performance across operating waveforms.
• Compact snap-in package: Radial can with snap-in terminals provides a secure PCB mount and consistent mechanical placement.
• Wide temperature range: -40°C to 105°C rating enables use across broad industrial environments.
• RoHS compliant: Meets RoHS requirements for regulated substance control.
