LGN2G221MELA35

The LGN2G221MELA35 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose electronic applications. It provides 220 µF capacitance at a 400 V rating in a compact, snap-in radial can package and is rated for operation up to 105°C.

Engineered for durability, this part withstands 3000 hours of rated ripple current at 105°C and is RoHS compliant, offering a reliable high-voltage bulk capacitance option where long-term thermal endurance and compact case size are required.

Key Features

• Electrical Characteristics — 220 µF nominal capacitance with a rated voltage of 400 V and capacitance tolerance of -20% to +20%; polarized construction for DC applications.
• High‑temperature Endurance — Specified for operation from -25°C to +105°C with an endurance rating of 3000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current of 1.1 A at 120 Hz and 1.573 A at 100 kHz, enabling sustained AC ripple handling under operating conditions.
• Leakage and Loss — Leakage current meets I ≤ 3/√C (µA) after 5 minutes at 20°C; tangent of loss angle (tan δ) for the 160–420 V range has a maximum of 0.15 (measured at 120 Hz, 20°C).
• Low‑temperature Stability — Impedance stability characterized by Z(–25°C)/Z(+20°C) ≤ 4 for the applicable rated voltage range, supporting performance in colder ambient conditions.
• Compact, Serviceable Package — Snap‑in radial can package (L: 3.5 × D: 2.5 cm) that occupies one rank smaller case size compared with the LGU series; marked with white printing on a black sleeve.
• Regulatory — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronic designs — Provides bulk capacitance and high-voltage rating for circuits that require 220 µF at 400 V in a snap-in package.
• High-temperature environments — Suitable where sustained operation at or near 105°C and long ripple endurance (3000 hours) are required.
• Compact chassis installations — One-rank smaller case size than LGU offers a reduced footprint while retaining 400 V capability.

Unique Advantages

• Long thermal endurance — 3000-hour rated ripple-current endurance at 105°C supports designs requiring sustained high-temperature operation.
• High-voltage bulk capacitance — 220 µF at 400 V provides substantial energy storage in a single component for high-voltage systems.
• Measured ripple performance — Specified ripple current ratings at both low (120 Hz) and high (100 kHz) frequencies enable informed thermal and lifetime calculations.
• Compact snap‑in packaging — Radial, snap‑in can reduces assembly time and saves board space relative to larger case alternatives.
• Verified electrical stability — Low-temperature impedance and tan δ limits are defined for predictable behavior across the specified temperature range.
• Regulatory compliance — RoHS compliance simplifies environmental and materials assessments.
