LGJ2Z391MELC15

The LGJ2Z391MELC15 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGJ series, designed for general-purpose power applications. It delivers 390 µF capacitance at a 180 V rating in a compact low-profile φ35 × 15 mm can with snap-in mounting for secure PCB attachment.

Engineered for elevated-temperature operation, this capacitor supports an operating temperature range of −40°C to 105°C and a rated endurance of 2000 hours at 105°C, providing thermal robustness for continuous-power environments.

Key Features

• Electrical Performance — 390 µF capacitance with ±20% tolerance, rated at 180 V for general-purpose energy storage and decoupling.
• Ripple Current Capability — Low-frequency ripple current of 1.2 A at 120 Hz and high-frequency ripple handling of 1.8 A at 50 kHz to support AC ripple filtration across frequencies.
• Leakage Current — Low leakage current specified at 790 µA for this part, helping to minimize standby losses in power circuits.
• Thermal and Endurance Rating — Rated for −40°C to 105°C operation with a 2000 h life specification at 105°C to support prolonged high-temperature service.
• Package & Mounting — Radial, can-style snap-in package (φ35 × 15 mm) for secure snap-in mounting; supplied in tray packing and available for mass production.
• Polarized — Designed as a polarized electrolytic capacitor; observe polarity in application.

Typical Applications

• General-purpose power filtering — Smoothing and filtering of DC rails in general-purpose electronic equipment.
• Power supply decoupling — Bulk decoupling and transient support in general-purpose power circuits.
• Energy buffering for general circuits — Short-term energy storage and ripple absorption where a compact, high-voltage electrolytic is required.

Unique Advantages

• Compact low-profile form — φ35 × 15 mm can provides significant capacitance in a shallow package for space-constrained designs.
• High temperature endurance — Rated to 105°C with 2000 h life, offering reliable performance in elevated-temperature environments.
• Dual-frequency ripple capability — Specified ripple current at both 120 Hz and 50 kHz (1.2 A and 1.8 A respectively) to handle a range of switching and line-frequency conditions.
• Predictable leakage — Measured leakage current of 790 µA aids in budgeting standby current in power-sensitive designs.
• Secure snap-in mounting — Snap-in terminals provide robust mechanical attachment for through-hole assemblies in production environments.
• Mass-production ready — Tray packing and production status suitable for volume manufacturing and assembly processes.
