LGJ2Z221MELB15

The LGJ2Z221MELB15 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGJ series designed for general-purpose power applications. It pairs a low-profile, radial can package (φ30 × 15 mm) with high ripple capability and extended endurance to support robust power-conditioning needs in production assemblies.

Key attributes include a 220 µF nominal capacitance at 180 V rating, ±20% tolerance, and rated operation across −40°C to 105°C, offering a balance of compact size, thermal margin, and ripple handling for mass-production environments.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with a 180 V rated voltage and ±20% tolerance for predictable bulk energy storage and DC bus support.
• Snap‑in Radial Package: Radial, can-style snap-in terminals in a low-profile φ30 × 15 mm body enable secure mechanical mounting for through‑hole assemblies and streamlined automated placement (tray packing).
• High Ripple Current Capability: Rated for 850 mA at 120 Hz (low frequency) and 1.275 A at 50 kHz (high frequency), supporting applications with elevated AC ripple content.
• Wide Operating Temperature: Specified for −40°C to 105°C operation, enabling use across a broad thermal envelope.
• Long Endurance: 2000 hours life/endurance at 105°C, suitable for designs that require extended high-temperature operation.
• Leakage Performance: Measured leakage current of 590 µA and leakage current guidance per the series datasheet formula (I ≤ 3√(C·V) µA after 5 minutes at 20°C) for predictable stand-by behavior.

Typical Applications

• General Purpose Power Systems: Bulk energy storage and decoupling in general-purpose power electronics where snap-in mounting and higher ripple capability are required.
• Production Assemblies (Tray Packed): Designed for mass-production environments with tray packing to support efficient assembly workflows.
• Compact, High‑Temperature Environments: Low-profile φ30 × 15 mm body and 105°C rating make it suitable for space-constrained boards exposed to elevated operating temperatures.

Unique Advantages

• High ripple handling: Provides 850 mA at 120 Hz and 1.275 A at 50 kHz, reducing thermal stress and improving reliability in ripple-heavy circuits.
• Compact low-profile package: φ30 × 15 mm size conserves board height while delivering substantial capacitance for bulk storage.
• Snap-in mechanical robustness: Snap-in terminals offer secure through‑hole retention for vibration resistance and simplified assembly.
• Extended high-temperature endurance: 2000 hours at 105°C supports longer operational life in elevated-temperature applications.
• Measurable leakage behavior: Specified leakage current (590 µA) and datasheet leakage formula enable accurate power-loss budgeting and design validation.
• Manufacturing-friendly packaging: Tray packing and mass-production readiness streamline procurement and board-level assembly processes.
