LLG2W181MELA30

The LLG2W181MELA30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LLG series, offering 180 µF capacitance at a 450 V rated voltage. Designed as a smaller-sized snap-in solution within the LLG family, it targets general-purpose power applications where high-voltage handling, reliable ripple performance and a compact footprint are required.

Key value propositions include high ripple-current capability at both low and high frequencies, a 2000 h endurance rating at 85°C, low leakage current, and a φ25 × 30 mm snap-in can that supports equipment downsizing while maintaining robust electrical performance.

Key Features

• Electrical Core 180 µF capacitance with ±20% tolerance and a 450 V rated voltage for high-voltage applications.
• Ripple Current Capability Supports 1.300 A at 120 Hz (low frequency) and 1.859 A at 100 kHz (high frequency), enabling effective smoothing and ripple handling across a range of operating frequencies.
• Leakage and Loss Low leakage current specified at 850 µA, and a loss tangent rating aligned with the LLG series specifications for reliable electrical behavior.
• Reliability & Endurance Rated for 2000 hours at 85°C under DC bias plus rated ripple current, meeting endurance limits for sustained high-temperature operation.
• Operating Range Designed to operate between −25°C and 85°C, consistent with the 400–450 V category limits in the LLG series.
• Package & Mounting Snap-in radial can (φ25 × 30 mm) for secure mechanical mounting; supplied in tray packing suitable for mass production.
• Compliance RoHS-compliant construction as part of the LLG series.

Typical Applications

• General-purpose power systems — Provides high-voltage capacitance and ripple handling for general-purpose power electronics designs that require 450 V rated components.
• Equipment downsizing — Smaller case sizing within the LLG series helps reduce component footprint where compact power assemblies are desired.
• High-frequency and low-frequency ripple management — Dual-spec ripple capability (120 Hz and 100 kHz) supports designers managing both low-frequency and high-frequency ripple in DC link and smoothing circuits.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage power rails without component substitution.
• Dual-frequency ripple performance: Explicit ripple current specs at 120 Hz (1.300 A) and 100 kHz (1.859 A) provide measurable guidance for thermal and EMI-related design trade-offs.
• Compact snap-in package: φ25 × 30 mm snap-in can reduces installed volume while providing robust mechanical mounting for mass-production assembly.
• Long endurance at elevated temperature: 2000 hours rated life at 85°C under rated conditions supports reliable operation in sustained thermal environments.
• Low leakage current: 850 µA leakage assists in maintaining energy efficiency and minimizing standby losses in power systems.
• RoHS compliance: Meets RoHS requirements for environmentally restricted substances.
