LGJ2F121MELC15

The LGJ2F121MELC15 is an aluminum electrolytic capacitor in Nichicon’s LGJ series, featuring a snap‑in terminal radial can in a low‑profile 35 × 15 mm package. It delivers 120 µF capacitance at a 315 V rated voltage with ±20% tolerance and is designed for general‑purpose applications that require a compact, high‑voltage electrolytic solution.

Key value propositions include robust ripple handling (specified low‑ and high‑frequency ripple currents), a 2000‑hour endurance rating at 105 °C, and tray packing for mass production—making it suited to production environments where consistent performance and repeatable assembly are important.

Key Features

• Capacitance & Tolerance — 120 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C for predictable energy storage.
• Rated Voltage — 315 V rated voltage to support higher‑voltage DC applications.
• Temperature Range & Endurance — Operating temperature −25 °C to 105 °C with a rated lifetime of 2000 hours at 105 °C.
• Ripple Current Capability — 550 mA at 120 Hz (low frequency) and 786.5 mA at 50 kHz (high frequency) to handle AC ripple stresses specified in the product data.
• Leakage Current & Polarization — Polarized device with 580 µA specified leakage current for the part as supplied.
• Package & Mounting — Low‑profile radial can, snap‑in terminal type, dimension φ35 × 15 mm and height seated max 15 mm for compact chassis mounting.
• Production & Packing — Tray packing and mass production availability for volume manufacturing and automated assembly processes.

Typical Applications

• General‑purpose power electronics — Use where a compact 315 V electrolytic with defined ripple capability and 2000‑hour endurance at 105 °C is required.
• Industrial equipment — Suitable for applications that need high‑voltage bulk capacitance in a low‑profile snap‑in package for secure mounting.
• Mass production assemblies — Tray packing and consistent specifications support repeatable installation and procurement for production lines.

Unique Advantages

• High working voltage: 315 V rating provides the margin needed for higher‑voltage DC systems without changing package form factor.
• Compact low profile: φ35 × 15 mm size and snap‑in mounting save chassis height while enabling secure installation.
• Documented ripple performance: Specified low‑ and high‑frequency ripple current ratings (550 mA at 120 Hz, 786.5 mA at 50 kHz) let designers match capacitor selection to actual ripple conditions.
• Thermal endurance: 2000 hours at 105 °C supports designs exposed to elevated operating temperatures with predictable life characteristics.
• Production ready: Tray packing and mass‑production availability simplify procurement and assembly for volume manufacturing.
