LGU2E221MELY

The LGU2E221MELY is a Nichicon LGU series aluminum electrolytic capacitor in a snap-in radial can package, rated 220 µF at 250 V. It is a polarized, snap‑in terminal type designed for general-purpose power electronics applications that require sustained performance at elevated temperatures.

Key value propositions include high-temperature endurance and defined ripple-current capability: the LGU series is specified to withstand 3000 hours of rated ripple current at 105°C, and this part is RoHS compliant.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High-Temperature Endurance — Specified to withstand 3000 hours of rated ripple current at 105°C, supporting long-term operation in warm environments.
• Ripple Current Performance — Rated ripple current: 1 A at 120 Hz (low frequency) and 1.5 A at 50 kHz (high frequency), giving predictable AC stress handling across frequency ranges.
• Operating Range — Operating temperature range from −40°C to +105°C, suitable for a wide span of ambient conditions.
• Package & Mounting — Radial, snap‑in can for secure board retention and straightforward assembly in power modules and chassis-mounted designs.
• Polarized Electrolytic — Conventional polarized design appropriate for DC filtering, bulk storage and smoothing applications.
• Regulatory Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint — Physical size approximately L: 3 × D: 2 cm for space-constrained power assemblies.

Typical Applications

• General-purpose power filtering — Smoothing and decoupling on 250 V DC rails where stable capacitance and high-temperature endurance are required.
• Industrial power supplies — Bulk capacitance and ripple handling for power conversion modules that must operate reliably at up to 105°C.
• Power conversion and control — Energy storage and ripple attenuation in converters and control circuitry that use snap‑in mounting for mechanical stability.

Unique Advantages

• Proven high-temperature life: 3000 hours endurance at 105°C under rated ripple current, providing predictable aging and replacement intervals.
• Frequency-aware ripple capability: Specified ripple currents at 120 Hz and 50 kHz support designs with both low- and high-frequency AC stress.
• Secure snap-in mounting: Radial snap‑in can ensures robust board retention for vibration-prone or mechanically demanding assemblies.
• Regulatory-ready: RoHS compliance simplifies integration into products targeting restricted-substance regulatory requirements.
• Compact form factor: Small physical footprint (approx. 3 × 2 cm) enables use in space-constrained power sections without sacrificing capacitance.
• Clear electrical specification: Polarized 220 µF / 250 V rating with ±20% tolerance for predictable DC filter design.
