LLS2Z681MELA

The LLS2Z681MELA is an aluminum electrolytic capacitor in Nichicon’s LLS series featuring a snap-in terminal, radial can package and polarized construction. It provides 680 µF capacitance at a rated voltage of 180 V and is specified for general-purpose applications.

Designed to withstand prolonged ripple stress, this part endures 3000 hours of rated ripple current at 85°C and is RoHS compliant, making it suitable for designs that require long-term stability within the stated operating temperature range.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 180 V and ±20% tolerance (measured at 120 Hz, 20°C).
• Snap-in Radial Can Package — Snap-in terminal type and radial can construction for secure chassis or PCB mounting in compatible assemblies.
• High Ripple Endurance — Specified to withstand 3000 hours of rated ripple current at 85°C, ensuring sustained performance under ripple-loading conditions.
• Rated Ripple Current — 2.5 A at 120 Hz and 3.75 A at 50 kHz, providing clear ripple-handling specifications for design verification.
• Operating Temperature Range — Rated for –40°C to +85°C (applicable to 16 to 250 V range), covering the product’s intended thermal envelope.
• Electrical Characteristics — Leakage current specified as I ≤ 3√CV (µA) after 5 minutes at 20°C; tangent of loss angle (tan δ) for 180 V is specified (max. 0.15) per the LLS series data.
• Durability and Shelf Life — Endurance: capacitance change within ±20% after 3000 hours with D.C. bias plus rated ripple at 85°C; shelf life conditions and voltage treatment requirements are defined in the LLS series specifications.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size — Compact dimensions: L: 3.0 cm × D: 2.5 cm, available in a snap-in radial can format.

Unique Advantages

• Documented ripple endurance — Withstanding 3000 hours at rated ripple current and 85°C provides a clearly specified lifetime parameter for thermal and ripple-stress planning.
• Frequency-specific ripple ratings — Published ripple current values at both 120 Hz and 50 kHz allow designers to size capacitors with frequency-dependent ripple in mind.
• Measurable electrical limits — Explicit leakage current formula and tan δ limits enable predictable design margins and verification against datasheet criteria.
• Wide negative-temperature capability — Rated down to –40°C for applicable voltages, with documented impedance ratios at low temperature to support cold-environment performance analysis.
• Regulatory compliance — RoHS conformity simplifies environmental compliance tracking in product BOMs and procurement.
