Overview of LLS2G681MELC – Aluminum Electrolytic Capacitor, Snap-in, 400 V / 680 µF

The LLS2G681MELC is an aluminum electrolytic capacitor from Nichicon’s LLS series featuring a snap-in terminal configuration and an 85°C standard rating. It provides 680 µF capacitance at a 400 V rated voltage with ±20% tolerance for general-purpose electronic applications.

Designed for designs that require high-voltage, high-capacitance, snap-in mounting, this part delivers defined ripple-current capability and long endurance for stable performance in sustained operating conditions.

Key Features

  • Capacitance & Voltage — 680 µF nominal capacitance at a 400 V rated voltage with ±20% tolerance, suitable where high-voltage bulk capacitance is required.
  • Snap-in Terminal Mounting — Radial can, snap-in package (φ35 × 50 mm) for secure board retention and easy insertion during assembly; supplied in tray packing for mass production.
  • Endurance — Rated for 3000 hours at 85°C when subjected to rated ripple current and DC bias, supporting long-term operation under rated conditions.
  • Ripple Current Performance — Low-frequency ripple current of 3.1 A at 120 Hz and high-frequency ripple current of 4.433 A at 50 kHz, enabling handling of continuous AC ripple across a range of frequencies.
  • Loss and Leakage Characteristics — Tangent of loss angle (tan δ) specified at 0.20 (max) measured at 20°C, 120 Hz; leakage current listed at 1560 µA to characterize DC leakage behavior after voltage application.
  • Operating Temperature Range — Rated for operation from −25°C to +85°C consistent with the 350–450 V category for the LLS series.
  • Regulatory Compliance — RoHS compliant.

Typical Applications

  • General Purpose — Bulk energy storage and smoothing in electronic systems that require a 400 V, 680 µF snap-in capacitor for general-purpose designs.
  • High-Voltage AC Ripple Management — Use in circuits where specified ripple current capability (3.1 A @120 Hz, 4.433 A @50 kHz) and endurance at 85°C are required.
  • Panel and Chassis-Mounted Power Modules — Snap-in, radial can package for secure mechanical retention in assemblies requiring tray-packed, mass-production components.

Unique Advantages

  • High-Voltage Bulk Capacitance: 400 V rating combined with 680 µF provides substantial DC-link or bulk capacitance where elevated voltages are present.
  • Defined Ripple Handling: Specified low- and high-frequency ripple currents (3.1 A at 120 Hz and 4.433 A at 50 kHz) help designers size capacitors against expected AC stress.
  • Proven Endurance: 3000 hours at 85°C under rated ripple and bias conditions supports sustained operation and predictable aging behavior.
  • Snap-In Mechanical Reliability: Snap-in terminal style and radial can package enable secure mounting for production assemblies and automated handling (tray packing).
  • Measured Electrical Parameters: Specified tan δ (0.20 max at 20°C, 120 Hz) and listed leakage current (1560 µA) provide clear electrical characterization for design verification.
  • RoHS Compliance: Compliant to RoHS requirements for materials and environmental standards.

Why Choose LLS2G681MELC?

LLS2G681MELC combines high-voltage capability, substantial capacitance, and snap-in mounting in a single, RoHS-compliant package from Nichicon’s LLS series. Its defined ripple-current ratings and 3000-hour endurance at 85°C provide predictable performance for designs that require sustained AC stress handling and long-term reliability under rated conditions.

This part is suited for designers and procurement teams specifying general-purpose, high-voltage aluminum electrolytic capacitors where clear electrical parameters (capacitance, voltage, tan δ, leakage, ripple current) and mechanical mounting (snap-in radial can) are priorities in production environments.
