LLG2G221MELA30

The LLG2G221MELA30 is a Nichicon LLG-series aluminum electrolytic capacitor in a snap-in terminal configuration. It provides 220 µF nominal capacitance at a 400 V rated voltage in a compact, radial can designed to support equipment downsizing.

Engineered for general-purpose applications, this polarized snap-in capacitor combines high-voltage capability, defined ripple handling, and an 85°C rated operating environment with RoHS compliance.

Key Features

• Electrical Performance — 220 µF nominal capacitance with a 400 V rated voltage and capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Ripple Current — Rated ripple currents of 1.4 A at 120 Hz and 2.002 A at 100 kHz, supporting AC ripple stress at both low and high frequency conditions.
• Temperature & Endurance — Operating temperature range of –25°C to +85°C (for 400 V rating) and a guaranteed endurance of 2000 hours at 85°C under D.C. bias plus rated ripple current with defined post-test limits for capacitance, tan δ, and leakage.
• Low-temperature Stability — Impedance stability specified with Z(–25°C)/Z(+20°C) = 8 for 400 V, giving predictable behavior near the low end of the operating range.
• Leakage Current Specification — Leakage current limit defined by I ≤ 3√(C·V) µA after 5 minutes at 20°C, allowing precise leakage budgeting in designs.
• Compact Snap-in Package — Radial, can-type snap-in mounting (one rank smaller case than LLS) to aid equipment downsizing and secure board installation.
• Electrical Loss — Tangent of loss angle (tan δ) maximum of 0.15 at rated voltages up to 400 V (measured at 120 Hz, 20°C), supporting predictable dissipation characteristics.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Physical Marking — White printing on a black sleeve for clear part identification.
• Package Dimensions — Size listed as L: 3 × D: 2.5 cm; polarized construction and snap-in terminals for through‑hole mounting.

Typical Applications

• General-purpose power circuits — Provides 220 µF at 400 V in designs requiring a compact, high-voltage electrolytic solution for energy storage and smoothing.
• Equipment downsizing projects — One rank smaller case size than LLS, suited where board space reduction and compact radial snap-in form factors are priorities.
• Snap-in mounting designs — Ideal where secure through-hole snap-in terminals are preferred for mechanical stability and ease of assembly.

Unique Advantages

• Compact high-voltage capability: 400 V rating with 220 µF capacitance in a reduced-case LLG package supports smaller power assemblies without sacrificing voltage margin.
• Defined ripple handling: Specified ripple currents at 120 Hz and 100 kHz help designers size capacitors to meet both low- and high-frequency ripple requirements.
• Durability at temperature: 2000-hour endurance at 85°C under rated conditions gives predictable life behavior for thermal and ripple-stressed applications.
• Predictable leakage and loss: Leakage current formula and tan δ limits allow accurate electrical budgeting during design and validation.
• RoHS compliant: Meets current RoHS directive requirements for environmentally conscious designs.
• Clear identification: White marking on a black sleeve simplifies inventory and assembly verification.
