LGU2C391MELY

The LGU2C391MELY is an aluminum electrolytic capacitor in a snap‑in terminal, radial can package designed for general purpose applications. It delivers 390 µF capacitance at a 160 V rating with polarization, and is built for sustained operation up to 105°C.

Key value comes from long high‑temperature endurance and specified ripple current performance, offering reliable bulk capacitance and ripple management where a snap‑in, board‑mounted can is required.

Key Features

• Capacitance & Voltage — 390 µF rated capacitance with a 160 V DC rating and ±20% tolerance for predictable energy storage and decoupling in polarized circuits.
• High‑Temperature Endurance — Specified to withstand 3000 hours of D.C. bias plus rated ripple current at 105°C, supporting long life under elevated operating temperatures.
• Operating Temperature Range — Rated for −40 °C to +105 °C, matching the series category range for 16 to 250 V parts and enabling deployment in warmer environments.
• Ripple Current Performance — Rated ripple current of 1.3 A at 120 Hz and 1.95 A at 50 kHz, providing defined AC stress handling for ripple suppression and bulk decoupling.
• Package & Mounting — Snap‑in terminal, radial can package (snap‑in) for secure board installation and mechanical stability.
• Polarized Construction — Polarized electrolytic design for DC applications where polarity is defined.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements.
• Compact Footprint — Physical dimensions noted as approximately L: 3 × D: 2 cm with a maximum seated height of 1.181 inches, useful for cabinet and chassis space planning.

Typical Applications

• General Purpose Electronics — Suited for circuits that require a 390 µF, 160 V polarized capacitor with snap‑in mounting and defined tolerance.
• High‑Temperature Environments — Appropriate where operation up to 105 °C and 3000 hours of endurance under rated ripple current are required.
• Board‑Level Bulk Capacitance — Provides bulk energy storage and ripple management in designs using radial, snap‑in can capacitors.

Unique Advantages

• Long High‑Temperature Lifetime: 3000 hours endurance at 105 °C under rated ripple current reduces the need for frequent replacements in hot operating conditions.
• Measured Ripple Ratings: Published ripple current values at 120 Hz and 50 kHz (1.3 A and 1.95 A respectively) let engineers size capacitors against actual AC stress requirements.
• Snap‑In Mechanical Reliability: Snap‑in terminal and radial can packaging provide robust board retention for vertical mounting and chassis installations.
• Clear Specification Set: Operating temperature, capacitance, voltage, tolerance, polarity, and physical dimensions are documented for straightforward BOM and layout decisions.
• Regulatory Compliance: RoHS compliance supports use in regions and products requiring restricted substance adherence.
