LLG2W331MELA45

The LLG2W331MELA45 is a Nichicon LLG series aluminum electrolytic capacitor in a snap-in terminal, smaller-sized snap-in can format. It delivers 330 µF capacitance at a 450 V rating and is intended for general-purpose power applications where high-voltage bulk capacitance and compact packaging are required.

Built for equipment downsizing and secure board mounting, this capacitor combines a compact φ25 × 45 mm can (L: 4.5 × D: 2.5 cm) with robust electrical performance including specified ripple current at both low and high frequencies and a 2000 hour endurance at 85 °C.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance rated for 450 V DC, suitable for high-voltage energy storage and smoothing in general-purpose circuitry.
• Snap-in Mounting — Snap-in terminal type and radial can package for reliable mechanical retention and straightforward assembly in power modules and assemblies.
• Ripple Current Performance — Low-frequency ripple current 1.95 A (120 Hz) and high-frequency ripple current 2.7885 A (100 kHz) to support both mains-frequency and higher-frequency ripple applications.
• Leakage Current — Specified leakage current of 1150 µA after rated voltage application, with datasheet guidance for leakage limits (I ≤ 3√CV μA) for reference.
• Endurance & Temperature — Rated for 2000 hours at 85 °C with post-test limits: capacitance change within ±20%, tan δ up to 200% of initial specified value, and leakage current not exceeding the initial specified value.
• Low-Temperature Behavior — For the 400–450 V range, impedance ratio Z(–25 °C)/Z(+20 °C) is specified up to 8, and tan δ (max.) for 450 V is 0.20 (measured at 120 Hz, 20 °C), enabling predictable performance across the stated operating range.
• Polarized Aluminum Electrolytic — Standard polarized construction for general-purpose DC power applications.
• RoHS Compliant & Packaging — RoHS-compliant construction; supplied in tray packing for factory assembly.

Typical Applications

• General-purpose power equipment — Bulk smoothing and DC-link energy storage in general-purpose power designs that require 450 V rated capacitance.
• Compact/downsized systems — Suited for equipment downsizing where a one-rank-smaller case size and snap-in mounting simplify compact power module layouts.
• High-voltage AC/DC converter modules — Provides high-voltage capacitance and ripple handling for converters and power supply stages operating near the 450 V class.

Unique Advantages

• High-voltage bulk capacitance: 330 µF at 450 V gives substantial energy storage in a compact φ25 × 45 mm can for high-voltage designs.
• Dual-frequency ripple capability: Specified ripple current at both 120 Hz and 100 kHz supports designs that must manage both mains-frequency and high-frequency switching ripple.
• Compact, snap-in form factor: Snap-in terminals and a smaller-sized LLG case help reduce PCB footprint and simplify assembly for high-density power boards.
• Defined endurance specification: 2000 hours at 85 °C with clear post-test limits for capacitance, tan δ, and leakage current provides predictable life behavior for thermal-stressed applications.
• Low-temperature impedance data: Specified impedance ratio at –25 °C for the 400–450 V range enables design decisions for cold-start and low-temperature performance.
• Regulatory compliance and packaging: RoHS-compliant construction and tray packing support production workflows and environmental requirements.
