LLS2E331MELZ

The LLS2E331MELZ from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LLS series designed for general-purpose use. It delivers 330 µF capacitance at a 250 V rating with a compact φ22 × 30 mm can and radial snap-in mounting.

Engineered for durable operation, this component is specified for -40°C to 85°C operation, 3000 hours endurance at 85°C under rated ripple current, and RoHS compliance—making it suitable for designs that require reliable bulk capacitance with elevated ripple capability.

Key Features

• Form Factor and Mounting Snap-in terminal type in a radial can (φ22 × 30 mm) for robust vertical mounting and secure board retention.
• Rated Capacitance & Voltage 330 µF nominal capacitance at 250 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Ripple Current Performance 1.66 A at 120 Hz (low frequency) and 2.49 A at 50 kHz (high frequency) rated ripple currents for handling AC ripple stress.
• Leakage and Loss Specified leakage current of 860 µA and a tangent of loss angle (tan δ) of 0.15 at 20°C and 120 Hz for the 250 V rating.
• Endurance Withstands 3000 hours of rated ripple current at 85°C; meets endurance criteria for capacitance change, tan δ, and leakage after recovery to 20°C as defined in the datasheet.
• Operating Range and Compliance Rated for operation from -40°C to 85°C and compliant to RoHS (2011/65/EU,(EU)2015/863).
• Marking Printed with white lettering on a black sleeve for clear identification on assemblies.

Typical Applications

• General Purpose Power Systems Suitable where a 250 V, 330 µF aluminum electrolytic capacitor is required for bulk capacitance in general-purpose designs.
• Industrial Equipment (General Purpose) Designed for general-purpose industrial circuits that require stable capacitance and ripple handling up to the specified limits.
• Electronic Assemblies Useful in assemblies that require a snap-in radial can capacitor with documented endurance at 85°C and RoHS compliance.

Unique Advantages

• High Rated Ripple Capability Dual-spec ripple ratings (1.66 A at 120 Hz and 2.49 A at 50 kHz) provide defined performance across common ripple frequency ranges.
• Documented Endurance 3000 hours at 85°C under rated ripple current provides a measurable durability metric for design validation.
• Compact Snap-In Package φ22 × 30 mm radial, snap-in construction offers a space-efficient solution with secure mounting for vertical assemblies.
• Controlled Dissipation Factor tan δ of 0.15 at 20°C/120 Hz for the 250 V rating, supporting predictable AC loss behavior in designs.
• RoHS Compliance Meets RoHS directive requirements (2011/65/EU,(EU)2015/863) for regulated materials.
