LGJ2D681MELC20

The LGJ2D681MELC20 from Nichicon is a snap-in terminal, aluminum electrolytic capacitor in the LGJ series, rated at 680 µF and 200 V. It combines a low-profile φ35 × 20 mm can with snap-in mounting for robust board retention and high-current handling.

Designed for general-purpose power applications, the part offers high ripple-current capability and extended endurance (3000 hours at 105°C), making it suitable for systems that require stable bulk capacitance and reliable performance across –40°C to 105°C.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with ±20% tolerance and a 200 V rated voltage for high-energy storage in a compact form.
• Ripple Current Performance — Rated ripple current of 1.52 A at 120 Hz (low frequency) and 2.28 A at 50 kHz (high frequency), supporting applications with significant AC ripple components.
• Endurance & Temperature Range — 3000 hours rated lifetime at 105°C and an operating range from –40°C to 105°C for extended reliability under elevated temperature conditions.
• Leakage Current & Loss — Specified leakage current and loss characteristics consistent with the LGJ series: leakage current measured after standard voltage application and a maximum tan δ applicable at rated voltage.
• Package & Mounting — Radial, can-type snap-in package (φ35 × 20 mm) with snap-in terminals for secure vertical mounting and tray packing for mass production handling.
• Polarized Design — Polar electrolytic construction for DC bulk capacitance applications where polarity is observed.

Typical Applications

• General-purpose power systems — For designs requiring 680 µF at 200 V with high ripple capability and long-term endurance at elevated temperatures.
• Industrial power supplies — Suitable where a snap-in, high-voltage electrolytic capacitor with 3000 h life at 105°C is needed for bulk energy storage.
• Mass-production assemblies — Tray-packed snap-in package streamlines assembly in volume manufacturing environments.

Unique Advantages

• High voltage capacity: 200 V rating provides headroom for higher-voltage DC bus and energy storage needs.
• Elevated ripple handling: Combined low- and high-frequency ripple ratings (1.52 A at 120 Hz, 2.28 A at 50 kHz) support circuits with significant AC current components.
• Long endurance at 105°C: 3000-hour lifetime rating at 105°C supports designs exposed to sustained high operating temperatures.
• Low-profile, secure mounting: φ35 × 20 mm can with snap-in terminals offers compact vertical mounting and reliable board attachment for production assemblies.
• Clear specification set: Polarized aluminum electrolytic construction with defined tolerance (±20%) and leakage parameters for predictable design integration.
