LGW2G221MELZ45

The LGW2G221MELZ45 is a snap‑in terminal aluminum electrolytic capacitor rated at 220 µF and 400 V. It is designed for general‑purpose applications that require high ripple current handling and elevated temperature endurance.

Key value comes from its high ripple capability and endurance: it withstands 3000 hours of rated ripple current at 105°C, is RoHS‑compliant, and ships in a radial, can snap‑in package sized L: 4.5 × D: 2.2 cm.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 400 V rated voltage and a tolerance of ±20% (–20% to +20%).
• High Ripple Current & Endurance — Designed for high ripple environments and specified to withstand 3000 hours of rated ripple current at 105°C.
• Rated Ripple Current (measured) — 1.55 A at 120 Hz and 2.216 A at 50 kHz (part‑specific measured ripple current values provided).
• Operating Temperature — Specified operating range from –25°C to +105°C for the 400 V class.
• Mounting & Package — Snap‑in terminal, radial can package for panel or board mounting; physical size L: 4.5 × D: 2.2 cm.
• Leakage Current Specification — Leakage current meets I ≤ 3√(C·V) µA after 5 minutes at 20°C, per datasheet conditions.
• Compliance — RoHS‑compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Circuits — Use where a 400 V, 220 µF capacitor with high ripple capacity and 105°C endurance is required.
• High‑Ripple Environments — Suitable for circuits subject to continuous ripple current, supported by rated ripple current data and 3000‑hour endurance at 105°C.
• Board and Panel Installations — Snap‑in radial can package provides a robust mechanical mounting option for general‑purpose assemblies.

Unique Advantages

• Long High‑Temperature Endurance — Specified to tolerate 3000 hours of rated ripple current at 105°C, helping maintain capacitance and leakage performance in elevated‑temperature service.
• Measured Ripple Current Ratings — Published ripple current figures at 120 Hz and 50 kHz support design decisions for frequency‑dependent thermal management.
• High Voltage Capability — 400 V rating enables use in higher‑voltage general‑purpose power circuits without series stacking.
• Snap‑in Mounting — Radial, can snap‑in package simplifies installation in boards or panels where secure mechanical anchoring is required.
• RoHS Compliance — Conforms to relevant RoHS directives, supporting regulatory and environmental requirements.
• Clear Electrical Limits — Leakage current defined by I ≤ 3√(C·V) after 5 minutes at 20°C, enabling predictable design‑level leakage budgeting.
