LGL2G331MELB25

The LGL2G331MELB25 is a Nichicon LGL series snap-in aluminum electrolytic capacitor rated at 330 µF and 400 V. It is a radial, can-style, snap-in terminal type designed for general-purpose power electronics where high voltage and compact, robust mounting are required.

Key engineering attributes include a 105°C rated operating temperature, 2000 hours endurance at 105°C, low leakage characteristics and specified ripple current performance, delivering reliable bulk capacitance in a compact 30 × 25 mm package.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Snap‑in Mounting & Package — Radial, snap-in terminal can package (φ30 × 25 mm) for secure PCB mounting and mechanical stability in power assemblies.
• High‑Temperature Endurance — Rated for operation from –25°C to +105°C with an endurance specification of 2000 hours at 105°C under DC bias plus rated ripple current.
• Low Loss & Leakage — Specified tangent of loss angle (tan δ) max 0.15 at 120 Hz (400 V) and leakage current specified (1.08 mA for this size), enabling predictable loss and standby characteristics.
• Ripple Current Capability — Rated ripple current of 1.04 A at 120 Hz and 1.487 A at 50 kHz, supporting AC ripple handling in high-voltage circuits.
• Production and Packaging — Delivered in tray packing and currently in mass production for consistent supply availability.

Typical Applications

• General-purpose power designs — Provides high-voltage bulk capacitance for power electronics applications that require 330 µF at 400 V in a snap-in format.
• High-temperature systems — Suited for equipment operating up to 105°C thanks to a 2000 hour endurance rating at that temperature.
• Compact power assemblies — The φ30 × 25 mm footprint and snap-in can package deliver compact bulk capacitance where board space and secure mounting are important.

Unique Advantages

• High-voltage bulk capacitance: 330 µF at 400 V provides substantial energy storage for 400 V class circuits without increasing part count.
• Robust thermal endurance: 2000 hours at 105°C ensures long-term performance in elevated-temperature environments.
• Predictable electrical behavior: Defined tan δ (max 0.15) and leakage current (1.08 mA) enable reliable loss and standby current budgeting in designs.
• Snap-in mechanical reliability: Snap-in terminals provide secure PCB retention suited to assemblies exposed to vibration or handling.
• Frequency-aware ripple performance: Specified ripple current ratings at 120 Hz and 50 kHz support both low- and higher-frequency ripple conditions.
• Production-ready packaging: Tray packing and mass-production status support volume procurement and repeatable assembly processes.

Why Choose LGL2G331MELB25?

The LGL2G331MELB25 positions itself as a compact, high-voltage electrolytic solution for general-purpose power applications that demand 330 µF at 400 V, durable performance at elevated temperatures, and secure snap-in mounting.
