LLG2E681MELB25

The LLG2E681MELB25 is an aluminum electrolytic capacitor in a snap-in terminal can designed for general-purpose power applications. It delivers 680 µF capacitance at a 250 V rating in a compact φ30×25 mm case intended for equipment downsizing and high-density assemblies.

Key attributes include an operating temperature range of −40°C to 85°C, 2000 hours endurance at 85°C under rated conditions, RoHS compliance, and tray packing tailored for mass production and automated handling.

Key Features

• Electrolytic Snap‑In Package Radial, can-type snap-in mounting provides secure board retention and high current handling for through‑hole power assemblies.
• Electrical Ratings 680 µF nominal capacitance with ±20% tolerance and a 250 V rated voltage suitable for higher‑voltage power rails.
• Temperature and Endurance Rated for −40°C to 85°C operation with a specified endurance of 2000 hours at 85°C under DC bias plus rated ripple current.
• Ripple Current Capability Supports 2.5 A (120 Hz) low‑frequency ripple and 3.75 A (100 kHz) high‑frequency ripple, enabling effective smoothing and filtering under AC ripple stress.
• Leakage and Loss Characteristics Leakage current specified by I ≤ 3√CV (µA) after 5 minutes at 20°C; tangent of loss angle (tan δ) max 0.15 at 120 Hz, 20°C for rated voltages in the 160–400 V range.
• Compact Size φ30×25 mm body (L: 2.5 cm × D: 3 cm) offers a smaller case option suited for space‑constrained designs.
• Production‑Oriented Packing Tray packing and mass production readiness simplify handling and assembly for volume manufacturing.
• RoHS Compliant Manufactured in accordance with RoHS directives.

Typical Applications

• General-purpose power electronics — Bulk energy storage and smoothing where 680 µF at 250 V is required in general-purpose designs.
• Equipment downsizing — Compact φ30×25 mm case and one‑rank smaller sizing make it suitable for designs targeting reduced enclosure and board area.
• Power module filtering — Provides ripple filtering and DC bus decoupling with rated ripple current support at both low and high frequencies.
• Mass-production assemblies — Tray packing supports automated placement and efficient board‑level integration for high-volume manufacturing.

Unique Advantages

• High voltage capability: 250 V rating enables use on elevated DC rails while maintaining a compact form factor.
• Designed for continuous thermal stress: 2000 hours endurance at 85°C under rated conditions provides predictable life performance for sustained operation.
• Validated ripple performance: Defined ripple current ratings (2.5 A at 120 Hz, 3.75 A at 100 kHz) support reliable filtering in both low‑ and high‑frequency environments.
• Low leakage specification: Leakage current governed by I ≤ 3√CV (µA) ensures predictable standby and leakage behavior after application of rated voltage.
• Stable at low temperature: Low‑temperature impedance stability (Z(−25°C)/Z(+20°C) ≤ 4 for 160–250 V range) supports wider ambient use within the specified category temperature.
• Production-friendly packaging: Tray packing and mass production readiness reduce handling time and simplify integration into automated assembly lines.
