LGJ2G470MELA15

The LGJ2G470MELA15 is a low‑profile, snap‑in terminal aluminum electrolytic capacitor in Nichicon’s LGJ series, rated for 400 V and 47 µF capacitance with ±20% tolerance. It is designed for general-purpose electronic applications that require high working voltage in a compact radial can package.

Key attributes include a 105°C operating temperature rating, 2000 hours endurance at 105°C, specified leakage current (410 µA), and documented ripple current performance at both low and high frequencies—making it suitable where thermal and ripple handling are critical design factors.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance at a rated voltage of 400 V with ±20% tolerance, providing predictable bulk capacitance for high‑voltage circuits.
• High‑temperature Endurance — Rated for operation from −25°C to 105°C with a guaranteed life of 2000 hours at 105°C, supporting sustained high‑temperature use.
• Low‑Profile Snap‑in Package — φ25 × 15 mm radial can with snap‑in terminals for secure chassis or board mounting and tray packing suitable for mass production.
• Ripple Current Performance — Specified ripple current of 350 mA at 120 Hz (low frequency) and 500.5 mA at 50 kHz (high frequency), enabling defined AC stress handling across common frequencies.
• Controlled Leakage — Leakage current specified at 410 µA to help manage standby losses and insulation behavior after voltage application.
• Polarized, General‑Purpose Design — Polar type capacitor intended for general‑purpose electronic applications within its electrical and temperature ratings.

Typical Applications

• General‑purpose power supplies — Suitable for use where 400 V, 47 µF bulk capacitance is required in general‑purpose supply circuits.
• Industrial electronics — Appropriate for general‑purpose industrial designs that require elevated temperature endurance and defined ripple handling.
• Mass production assemblies — Tray packing and snap‑in mounting make this part suitable for high‑volume manufacturing environments using radial snap‑in components.

Unique Advantages

• High working voltage in a compact footprint: 400 V rating combined with a φ25 × 15 mm low‑profile can provides significant capacitance without large axial height.
• Documented high‑temperature life: 2000 hours at 105°C gives designers a clear endurance metric for thermal planning.
• Dual‑frequency ripple data: Specified ripple current at both 120 Hz and 50 kHz enables reliable selection for circuits operating across common frequency ranges.
• Stable leakage characteristic: Specified leakage current of 410 µA supports predictable insulation behavior after voltage application.
• Snap‑in mounting for secure installation: Radial, snap‑in terminal package simplifies mechanical retention in chassis and assembly workflows.
• Manufacturer series backing: Part of Nichicon’s LGJ series, offering consistent series‑level specifications for design continuity.
