LLG2G681MELC35

The LLG2G681MELC35 is a 680 µF, 400 V aluminum electrolytic capacitor in Nichicon’s LLG snap-in terminal series. It delivers high-voltage bulk capacitance in a compact, snap-in radial can designed for general-purpose power applications.

Engineered for equipment downsizing, the LLG series offers a one-rank smaller case compared to the LLS series and is RoHS compliant. Typical use cases include high-voltage smoothing and energy storage where board space and reliable performance at up to 85°C are important.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance rated at 400 V, suitable for high-voltage power rails and bulk energy storage.
• Snap-in Radial Can Package — Snap-in terminal type for secure PCB mounting and mechanical stability in radial, can-style packaging.
• Compact Size for Downsizing — One rank smaller case size than Nichicon LLS series, intended to help reduce equipment footprint; physical dimension listed as 3.5 × 3.5 cm.
• Operating Temperature & Endurance — Rated for operation from –25°C to +85°C (for 400 V) with endurance specified as 2000 hours at 85°C under rated DC bias plus rated ripple current.
• Ripple Current Performance — Rated ripple current of 2.69 A at 120 Hz and 3.847 A at 100 kHz, supporting both low- and high-frequency ripple conditions.
• Leakage Current Spec — Leakage current limited by I ≤ 3√(C·V) µA after 5 minutes at 20°C, providing predictable leakage behavior for design calculations.
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20°C.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies — Bulk smoothing and energy storage on 400 V rails where high capacitance and reliable ripple handling are required.
• Industrial Power Electronics — Compact filtering in equipment that benefits from reduced case size while maintaining 400 V capability.
• General-Purpose Electronic Equipment — High-voltage decoupling and energy buffering in space-constrained power designs.

Unique Advantages

• Space-efficient design: One-rank smaller case than LLS helps reduce enclosure and PCB area without sacrificing capacitance or voltage rating.
• High-voltage capability: 400 V rating supports higher-voltage power rails and circuits where bulk capacitance is needed.
• Robust ripple handling: Specified ripple currents at 120 Hz and 100 kHz allow predictable thermal and performance planning across frequencies.
• Defined endurance: 2000 hours at 85°C under rated conditions provides a clear specification for life and reliability planning.
• Predictable leakage behavior: Leakage current governed by the I ≤ 3√(C·V) rule simplifies design margin calculations and system modeling.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements for modern electronics manufacturing.
