The LGJ2D471MELB20 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power electronics requiring a compact, low‑profile solution. It delivers 470 µF capacitance at 200 V with a low‑profile φ30 × 20 mm can and snap‑in mounting for secure, high‑density board installation.

Engineered for elevated operating stress, this part supports an operating temperature range of −40°C to +105°C and a rated endurance of 3000 hours at 105°C, offering a balance of energy storage, ripple handling and long‑term reliability for industrial and electronic power systems.

Key Features

• Capacitance & Tolerance — 470 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, suitable for bulk filtering and energy storage roles.
• Rated Voltage — 200 V DC rating for mid‑to‑high voltage power rails and DC bus applications.
• High Temperature Endurance — Rated lifetime of 3000 hours at 105°C, providing stable performance under elevated thermal stress.
• Ripple Current Capability — 1.12 A at 120 Hz (low frequency) and 1.68 A at 50 kHz (high frequency), supporting AC ripple and switching‑frequency currents in power circuits.
• Leakage Current — Specified leakage current of 910 µA (after rated voltage application), enabling predictable standby characteristics.
• Snap‑in Radial Package — φ30 × 20 mm low‑profile can with snap‑in terminals for robust mechanical retention and easy insertion in high‑density assemblies.
• Wide Operating Temperature — −40°C to +105°C operational range for use across varied ambient environments.
• Polarized Construction — Standard polarized electrolytic design for DC filtering and energy storage applications.

Typical Applications

• Power supply filtering — Bulk smoothing and decoupling on 200 V DC rails where 470 µF capacitance and rated ripple current are required.
• Industrial power electronics — Energy storage and ripple handling in converters and control systems operating up to 105°C.
• General-purpose electronic equipment — Reliable polarized capacitance for assemblies that need compact, snap‑in mounted electrolytics.

Unique Advantages

• Compact low‑profile form factor — φ30 × 20 mm can provides substantial capacitance in a short length, easing mechanical layout in confined spaces.
• High temperature endurance — 3000‑hour rating at 105°C supports long service life in thermally demanding installations.
• Robust ripple handling — Specified ripple currents at both low and high frequencies accommodate switching and AC ripple stresses.
• Secure snap‑in mounting — Snap‑in terminals offer strong mechanical retention for high‑vibration or dense assemblies.
• Predictable leakage behavior — Specified leakage current enables designers to account for standby and bias currents in power budgets.
