LLG2W471MELB40

The LLG2W471MELB40 is a Nichicon LLG series aluminum electrolytic capacitor in a snap-in terminal format, offering 470 µF capacitance at a 450 V rating. It is a smaller-sized, snap-in can designed for general-purpose equipment where a compact high-voltage electrolytic is required.

Designed for applications that need high ripple capability and robust endurance, this RoHS-compliant component delivers a balance of voltage handling, ripple performance and compact packaging to support equipment downsizing efforts.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 450 V rated voltage and capacitance tolerance of -20% to +20%.
• Snap-In Package — Snap-in terminal type in a radial can (φ30 × 40L) for secure board mounting and easy placement in tray packing.
• Ripple Current Performance — Low-frequency ripple current of 2.32 A (120 Hz) and high-frequency ripple current of 3.318 A (100 kHz), supporting demanding AC ripple conditions within specified limits.
• Leakage and Dissipation — Specified leakage current of 1370 µA and tan δ (DF) of 0.20 measured at 20°C, 120 Hz, enabling predictable loss characteristics.
• Temperature & Endurance — Rated for operation from -25°C to +85°C with an endurance of 2000 hours at 85°C under DC bias plus rated ripple current.
• Compliance & Series Benefits — Part of the LLG series (smaller-sized compared with LLS) and compliant with RoHS directives for environmental compliance.

Typical Applications

• General Purpose Equipment — For use in general-purpose designs that require a high-voltage, snap-in electrolytic capacitor with reliable endurance.
• Equipment Downsizing — Suited to products benefiting from smaller case sizes where space is at a premium.
• High-Voltage Power Modules — Applicable where a 450 V rated electrolytic is needed for filtering and energy storage in compact power assemblies.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage circuits without stacking multiple components.
• Compact snap-in form factor: φ30 × 40L radial can and snap-in terminals combine secure mounting with reduced board footprint.
• Robust ripple handling: Specified ripple currents at both low and high frequencies support designs with significant AC ripple stress.
• Proven endurance: 2000 hours at 85°C under rated conditions provides predictable lifetime behavior for long-term use.
• Measured electrical characteristics: Defined leakage current (1370 µA) and tan δ (0.20 at 20°C, 120 Hz) enable accurate thermal and loss budgeting.
• RoHS compliant: Meets RoHS requirements for environmental regulations.
