LGU2D331MELA

The LGU2D331MELA from Nichicon is a snap‑in, polarized aluminum electrolytic capacitor with 330 µF capacitance rated at 200 V. It is a general‑purpose, radial can (snap‑in) device designed for applications that require high ripple handling and extended endurance at elevated temperature.

Key attributes include a 105°C operating range, a 3000‑hour endurance at 105°C under rated ripple conditions, and RoHS compliance—delivering reliable performance in general‑purpose power electronics environments.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 200 V and capacitance tolerance of ±20% (–20% to +20%).
• High Temperature Endurance — Rated for 3000 hours at 105°C with D.C. bias plus rated ripple current applied; meets the endurance requirements when returned to 20°C.
• Ripple Current Performance — Low‑frequency ripple current of 1.25 A at 120 Hz and high‑frequency ripple current of 1.875 A at 50 kHz, specified for sustained operation.
• Loss & Leakage — Tangent of loss angle (tan δ) up to 0.15 (measured at 20°C, 120 Hz for this voltage class) and a specified leakage current of 770 µA.
• Temperature Range — Operating from –40°C to +105°C for robust performance across thermal conditions.
• Package & Mounting — φ25 × 25 mm radial can with snap‑in terminals; supplied in tray packing and listed as mass production status.
• Compliance — RoHS compliant.

Typical Applications

• General‑purpose power electronics — Provides bulk energy storage and ripple suppression where a 200 V, 330 µF snap‑in electrolytic capacitor is required.
• Industrial equipment — Suited to general‑purpose industrial designs that demand extended high‑temperature endurance and specified ripple handling.
• Power assemblies and modules — Useful in assemblies requiring radial can capacitors with snap‑in mounting and tray packing for automated handling.

Unique Advantages

• Designed for sustained ripple loading — Specified ripple current ratings and datasheet confirmation of withstanding 3000 hours at 105°C under rated ripple current ensure predictable lifetime under heavy ripple conditions.
• High‑temperature capability — Rated to operate up to 105°C, enabling deployment in warmer environments without derating beyond the stated temperature range.
• Compact snap‑in package — φ25 × 25 mm radial can with snap‑in terminals simplifies board mounting for power modules and reduces assembly complexity.
• Measured electrical characteristics — Specified tan δ (0.15 at 20°C, 120 Hz for this voltage class) and defined leakage current provide verifiable parameters for design and simulation.
• RoHS compliant and production ready — Tray packing and mass production status support procurement and manufacturing scale‑up.
