LLG2E681MELA35

The LLG2E681MELA35 is a Nichicon LLG series aluminum electrolytic capacitor with snap‑in terminals designed for general‑purpose applications. It delivers 680 µF at a 250 V rating in a compact, smaller-than-LLS case format, making it suited for equipment downsizing while maintaining electrolytic performance characteristics.

Designed for standard industrial operating conditions, the LLG2E681MELA35 is RoHS compliant and specified for operation from –40 °C to +85 °C with a documented endurance of 2000 hours at 85 °C under rated bias and ripple conditions.

Key Features

• Capacitance and Voltage: 680 µF rated capacitance at 250 V DC provides bulk energy storage and smoothing for general‑purpose circuits.
• Compact Snap‑In Package: Radial, can snap‑in termination enables secure PCB mounting and space‑efficient placement; one rank smaller case than the LLS series for equipment downsizing.
• Temperature Range: Specified operating range of –40 °C to +85 °C (applies to the 160–250 V rated range), supporting typical ambient conditions in general‑purpose equipment.
• Endurance: Rated for 2000 hours at 85 °C with DC bias plus rated ripple current; after endurance testing, capacitance change is within ±20%, tan δ within specified limits, and leakage current meets initial limits.
• Ripple Current Capability: Rated ripple current of 2.5 A at 120 Hz and 3.75 A at 100 kHz, supporting AC ripple handling across common power frequencies and higher‑frequency applications.
• Leakage Current Specification: Leakage current defined by I ≤ 3√CV (μA) after 5 minutes at 20 °C, enabling predictable leakage behavior for design calculations.
• Polarized Electrolytic: Polarized construction for DC bulk capacitance applications; marking is printed in white on a black sleeve for polarity and part identification.

Typical Applications

• General‑purpose power filtering: Bulk smoothing and decoupling in circuits where a compact 680 µF, 250 V snap‑in capacitor is required.
• Equipment downsizing: Applications that benefit from a smaller case size than LLS while retaining electrolytic performance.
• PCB snap‑in assemblies: Designs that require robust snap‑in mounting for through‑hole boards and reliable mechanical retention.

Unique Advantages

• Space‑efficient form factor: One rank smaller case than the LLS series, enabling reduced board area and overall equipment footprint.
• Clear performance limits: Endurance and leakage defined in the datasheet (2000 h at 85 °C; I ≤ 3√CV), allowing predictable life and maintenance planning.
• Solid ripple handling: Specified ripple currents at both 120 Hz and 100 kHz provide data for thermal and reliability assessments under realistic load conditions.
• RoHS compliant: Conforms to RoHS (2011/65/EU, (EU)2015/863), supporting regulatory requirements for lead‑free assemblies.
• Wide operating temperature: –40 °C to +85 °C operating range (for 160–250 V), suitable for typical general‑purpose environments.

Why Choose LLG2E681MELA35?

The LLG2E681MELA35 combines a high‑capacitance 680 µF, 250 V rating with a compact snap‑in can package from Nichicon’s LLG series. Its smaller case size relative to the LLS series and documented endurance make it a practical choice for designs prioritizing board‑space reduction without sacrificing electrolytic performance.

This part is well suited to engineers and procurement teams specifying general‑purpose electrolytic capacitors where predictable ripple handling, defined leakage behavior, RoHS compliance, and a proven 2000‑hour endurance at 85 °C are required.
