LGW2E471MELB25

The LGW2E471MELB25 is a Nichicon LGW series aluminum electrolytic capacitor in a snap-in terminal radial can. It provides 470 µF capacitance at a 250 V rating in a compact φ30 × 25 mm package and is specified for general-purpose power applications.

Designed for high ripple environments, this capacitor combines elevated ripple-current capability with a 3000-hour endurance rating at 105°C, delivering reliable bulk capacitance and smoothing where sustained thermal and ripple performance are required.

Key Features

• Capacitance & Rated Voltage — 470 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• High Ripple Current Capability — Rated ripple current of 2.2 A at 120 Hz (low frequency) and 3.3 A at 50 kHz (high frequency), supporting designs with significant AC ripple components.
• Endurance at Elevated Temperature — Specified for 3000 hours life when operated at 105°C with DC bias plus rated ripple current applied, supporting long-term operation in hot environments.
• Package & Mounting — Snap-in terminal, radial can package (φ30 × 25 mm) for secure board mounting and high mechanical retention on PCBs.
• Leakage Current Specification — Initial leakage current specified at 1020 µA after standard application of rated voltage (at 20°C testing conditions).
• Polarized, General-Purpose — Polarized electrolytic construction intended for general-purpose power filtering and bulk energy storage applications.
• RoHS Compliant — Meets RoHS requirements as indicated in the product documentation.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple reduction in general-purpose power supplies using the 470 µF/250 V rating and rated ripple-current capability.
• DC link and energy storage — Bulk capacitance for DC bus stabilization where sustained ripple current and thermal endurance are required.
• Industrial power electronics — General-purpose use in equipment with elevated operating temperatures up to 105°C and continuous ripple stress.

Unique Advantages

• Designed for high ripple environments — Explicit ripple-current ratings at 120 Hz and 50 kHz (2.2 A and 3.3 A) clarify performance across low and high frequency stress.
• Long high-temperature endurance — 3000 hours at 105°C under rated conditions supports predictable lifetime in thermally demanding applications.
• Secure snap-in mounting — Radial, snap-in can package (φ30 × 25 mm) provides robust mechanical retention on PCBs for vibration-prone assemblies.
• Clear electrical limits — Specified leakage current (1020 µA) and ±20% capacitance tolerance enable straightforward design margin calculations.
• RoHS compliance — Conforms to RoHS directives for regulatory alignment in commercial and industrial products.
