LGL2W391MELA50

The LGL2W391MELA50 from Nichicon is an ultra-smaller-sized aluminum electrolytic capacitor in a snap-in terminal package. With a 390 µF capacitance and 450 V rated voltage, it is designed for general-purpose high-voltage filtering and energy storage where compact size and elevated temperature endurance are required.

Key value comes from a combination of high-voltage capability, snap-in mounting for robust board retention, and extended life at elevated temperature: rated for operation from −25°C to 105°C and endurance of 2000 hours at 105°C.

Key Features

• Capacitance & Voltage — 390 µF capacitance at a 450 V rated voltage for high-voltage energy storage and smoothing.
• Snap-in Package (Radial Can) — Snap-in terminal mounting provides secure mechanical retention for vertical board installation; package size is approximately 25 × 50 mm (φ25 × 50 L).
• High-Temperature Endurance — Rated for continuous operation from −25°C to 105°C with an endurance specification of 2000 hours at 105°C.
• Electrical Stability — Capacitance tolerance ±20% and tangent of loss angle (tan δ) up to 0.20 at 450 V (measured at 120 Hz, 20°C).
• Leakage Current — Specified leakage current of 1.25 mA for predictable low-current behavior after voltage application.
• Ripple Current Handling — Rated ripple currents of 1.28 A at 120 Hz and 1.83 A at 50 kHz to support AC ripple filtering across frequency ranges.
• Packaging & Availability — Tray packing for board-level handling; product is in mass production.

Typical Applications

• General-purpose power systems — High-voltage smoothing and bulk energy storage in designs requiring 450 V capability and compact footprint.
• Power supply filtering — Ripple suppression and DC-link stabilization where rated ripple current and high-temperature endurance are important.
• Industrial electronics — Use in equipment that requires reliable capacitor performance at elevated ambient temperatures up to 105°C.

Unique Advantages

• 450 V rated voltage — Enables use in higher-voltage power circuits without series stacking.
• Compact, snap-in form factor — φ25 × 50 mm footprint delivers a smaller board impact while providing secure mechanical mounting.
• High-temperature rated life — 2000 hours at 105°C supports designs exposed to elevated operating temperatures and thermal stress.
• Measured ripple performance — Specified ripple currents at both 120 Hz and 50 kHz give designers quantifiable margins for filtering across frequency ranges.
• Predictable electrical characteristics — Clear limits on tan δ (0.20 at 450 V) and leakage current (1.25 mA) simplify end-of-line acceptance and system modeling.
• Mass-production availability — Tray-packed and in mass production for volume deployment and repeatable supply.
