LLG2W221MELZ40

The LLG2W221MELZ40 is a Nichicon LLG series aluminum electrolytic capacitor in a snap‑in terminal (radial can) package. This specific part delivers 220 µF at a rated 450 V and is designed for general-purpose applications where a compact, snap‑in electrolytic solution is required.

Built one rank smaller in case size than the LLS series, the LLG2W221MELZ40 is suited for equipment downsizing while remaining RoHS compliant.

Key Features

• Electrical Rating — 220 µF nominal capacitance with a 450 V rated voltage and a capacitance tolerance of ±20% (−20% to +20%).
• Package & Mounting — Snap‑in terminal type in a radial can package for secure PCB mounting and straightforward installation.
• Compact Dimensions — Size approximately L: 4 × D: 2.2 cm with a maximum seated height of 1.575 inch, offering a smaller case footprint (one rank smaller than LLS) for space‑constrained designs.
• Temperature & Endurance — Rated operating temperature range −25 °C to +85 °C (for 450 V rating) with an endurance specification of 2000 hours at 85 °C under DC bias plus rated ripple current.
• Ripple Current Capability — Specified ripple handling of 1.4 A at 120 Hz (low frequency) and 2.002 A at 100 kHz (high frequency), allowing predictable performance under rated ripple conditions.
• Leakage and Loss Characteristics — Leakage current meets I ≤ 3√(C·V) μA after 5 minutes at 20 °C; tangent of loss angle (tan δ) maximum for 450 V is 0.20 (measured at 120 Hz, 20 °C).
• Low‑temperature Stability — Impedance stability measured by Z(−25 °C)/Z(+20 °C) is specified (max 8 for 450 V), supporting defined behavior in colder operating conditions.
• RoHS Compliance — Manufactured in compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronics — Suited for broad general-purpose use where a 220 µF, 450 V electrolytic capacitor is required.
• Space-constrained equipment — One rank smaller case size than LLS makes this part appropriate for designs targeting equipment downsizing.
• High-voltage circuits — The 450 V rating supports applications that require higher DC voltage capability within the specified temperature range.

Unique Advantages

• Compact snap‑in footprint: One rank smaller case size than LLS provides a reduced board space impact while retaining a snap‑in radial can package for robust mounting.
• High voltage capability: 450 V rated voltage enables use in higher DC voltage applications without changing capacitor family.
• Defined endurance: 2000 hours at 85 °C under rated conditions gives a clear expectation of long‑term performance for thermal and bias stress scenarios.
• Quantified ripple handling: Specified ripple currents at both 120 Hz and 100 kHz allow designers to match the part to their ripple requirements.
• Measured low‑temperature behavior: Specified impedance ratio at −25 °C provides predictable performance in colder environments for the 450 V variants.
• RoHS compliant: Conforms to current RoHS directives for regulatory compliance in applicable markets.
