LGJ2C181MELZ15

The LGJ2C181MELZ15 from Nichicon is a snap-in terminal, large-can aluminum electrolytic capacitor in the LGJ series designed for general-purpose power applications. It provides 180 µF of capacitance at a 160 V rating in a compact, low-profile φ22 × 15 mm can.

Engineered for power-smoothing and energy-storage roles, this capacitor is aimed at industrial and electronic equipment designs that require polarized, high-voltage filtering with a 105°C operating range and a 2,000-hour endurance rating at elevated temperature.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a rated voltage of 160 V for bulk energy storage and smoothing in power rails.
• Temperature & Endurance — Rated for operation from −40°C to 105°C with a specified lifetime of 2000 hours at 105°C, supporting sustained high-temperature use.
• Ripple Performance — Low-frequency ripple current of 650 mA at 120 Hz and high-frequency ripple current of 975 mA at 50 kHz to support a range of switching and line-frequency conditions.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.2 (measured at 20°C, 120 Hz), giving a quantifiable dissipation factor for design calculations.
• Leakage Current — Leakage current specified at 500 µA, enabling predictable standby losses in power systems.
• Form Factor & Mounting — Snap-in radial can package (φ22 × 15 mm) with snap-in terminals for secure board mounting and straightforward assembly; packaged in trays for production handling.
• Polarity — Polarized electrolyte construction suitable for DC filtering and smoothing applications.

Typical Applications

• Industrial Power Supplies — Bulk filtering and energy smoothing on DC rails where 160 V rating and high ripple capability are required.
• Motor Drives & Inverters — DC-link smoothing and decoupling in power conversion stages that operate near elevated temperatures.
• Power Conversion Modules — Support for switching supplies and intermediate buses requiring stable capacitance and defined dissipation characteristics.
• General Electronic Equipment — Energy storage and filtering in commercial and industrial electronics designed for extended operating life at up to 105°C.

Unique Advantages

• High working voltage in a compact can: 160 V rating combined with a φ22 × 15 mm low-profile package lets designers save board space while maintaining voltage headroom.
• Robust high-temperature endurance: 2000 hours at 105°C provides predictable long-term performance in thermally demanding environments.
• Dual-frequency ripple capability: Specified ripple currents at both 120 Hz (650 mA) and 50 kHz (975 mA) support designs that must handle line-frequency and switching-frequency stress.
• Quantified loss and leakage specs: tan δ (0.2 at 20°C, 120 Hz) and 500 µA leakage current give clear design inputs for thermal and loss budgeting.
• Snap-in mounting for production assembly: Snap-in terminals and tray packing facilitate reliable PCB installation and automated handling.
