LLG2W221MELB25

The LLG2W221MELB25 is a 220 µF, 450 V aluminum electrolytic capacitor from Nichicon’s LLG series, featuring a snap-in terminal radial can designed for board-mounted installations. The LLG series delivers a one-rank smaller case size than LLS, making this part well suited for equipment downsizing where high-voltage capacitance and compact packaging are required.

Engineered for general-purpose use, this polarized capacitor is RoHS compliant and specified for operation from −25°C to 85°C with a rated lifetime of 2000 hours at 85°C under rated conditions.

Key Features

• Electrical performance — 220 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C; rated voltage 450 V.
• Leakage and loss characteristics — Leakage current specified by I ≤ 3√CV (µA) after 5 minutes at 20°C; tangent of loss angle (tan δ) max 0.20 at 450 V (measured at 120 Hz, 20°C).
• Low-temperature stability — Impedance stability characterized with Z(−25°C)/Z(+20°C) up to 8 for 400–450 V ratings, supporting operation down to −25°C.
• Ripple current capability — Rated ripple current of 1.4 A at 120 Hz (low frequency) and 2.002 A at 100 kHz (high frequency).
• Reliability and endurance — Endurance verified for 2000 hours at 85°C under DC bias plus rated ripple current; after the test the capacitor meets defined limits for capacitance change (±20%), tan δ (≤ 200% of initial specified value), and leakage current (≤ initial specified value).
• Compact mechanical design — Snap-in radial can package with dimensions L: 2.5 × D: 3 cm, and max seated height 2.5 cm; one rank smaller case than LLS to support equipment downsizing.
• Environmental compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power electronics — Provides high-voltage bulk capacitance for board-mounted power stages where a compact snap-in radial can is preferred.
• Equipment downsizing — One-rank smaller case size than LLS makes the part suitable for designs targeting reduced enclosure volume without sacrificing voltage rating.
• Industrial and commercial systems — Polarized, high-voltage capacitance for filter, energy storage, or smoothing functions in general-purpose equipment operating within −25°C to 85°C.

Unique Advantages

• High voltage in a compact package: 450 V rating combined with a reduced case size helps integrate high-voltage capacitance into space-constrained designs.
• Proven endurance at elevated temperature: 2000 hours at 85°C under rated conditions with defined post-test limits, providing predictable long-term behavior in thermal stress environments.
• Secure PCB mounting: Snap-in terminal radial can ensures robust mechanical retention for board-mounted applications.
• Measurable ripple performance: Specified ripple current values at both low and high frequencies allow designers to assess thermal and ripple handling for their application.
• Regulatory compliance: RoHS compliance supports environmental requirements for modern equipment manufacturing.
