LGY1K332MELA45

The LGY1K332MELA45 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGY series, designed for long-life, high-reliability power applications. It combines 3.3 mF capacitance with an 80 V rating and a snap-in can package to address industrial power supply and ballast duties where sustained ripple endurance and dependable performance are required.

Engineered for continuous operation up to 105°C with a 5,000‑hour ripple endurance rating, this polarized capacitor is suitable for general-purpose power filtering and energy storage in demanding environments while meeting RoHS (2011/65/EU, (EU)2015/863) requirements.

Key Features

• Capacitance & Voltage — 3.3 mF capacitance rated at 80 V for bulk filtering and energy storage in higher-voltage power stages.
• Long Life Assurance — Endurance specification of 5,000 hours at 105°C with DC bias plus rated ripple current applied, supporting sustained operation in high-temperature, high-stress environments.
• Snap‑in Terminal Can — Radial, can-style snap-in package for secure mechanical mounting and simplified board assembly in power modules.
• Wide Operating Temperature — Rated for −40°C to +105°C to cover a broad range of industrial operating conditions.
• Ripple Current Handling — Rated ripple current of 2.4 A at 120 Hz and 2.76 A at 50 kHz, enabling reliable RMS ripple absorption in power conversion and ballast circuits.
• Polarized, ±20% Tolerance — Polarized construction with capacitance tolerance of −20% to +20% for predictable performance in DC power applications.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk filtering and ripple smoothing in high-reliability PSU designs operating at elevated temperatures.
