LLS1E123MELB

The LLS1E123MELB is a snap-in terminal type aluminum electrolytic capacitor designed for general-purpose electronic use. It provides 12 mF capacitance at a 25 V rating in a radial can snap-in package and is polarized for DC applications.

Engineered to withstand rated ripple current for 3000 hours at 85°C and compliant with RoHS (2011/65/EU, (EU)2015/863), this capacitor targets designs that require durable ripple-current capability, compact snap-in mounting, and standard industrial temperature range performance.

Key Features

• Capacitance & Voltage — 12 mF capacitance with a 25 V rated voltage and ±20% tolerance, providing predictable bulk capacitance for general-purpose circuits.
• Snap-In Mounting — Radial, can snap-in package for secure PCB mounting and straightforward assembly in power modules and chassis-mounted applications. Dimensions: L: 2.5 × D: 3 cm.
• Ripple Current Performance — Capable of 3.8 A at 120 Hz and 4.37 A at 50 kHz, supporting designs with significant AC ripple on DC rails.
• Endurance at Elevated Temperature — Rated to withstand 3000 hours of rated ripple current at 85°C, enabling reliable performance under sustained thermal stress.
• Operating Temperature Range — −40°C to +85°C, suitable for a wide range of ambient conditions within standard industrial limits.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), meeting common environmental regulatory requirements.

Typical Applications

• General-Purpose Power Supplies — Use where a 12 mF/25 V snap-in electrolytic capacitor is required for bulk capacitance and ripple-current handling in general-purpose power conversion and filtering.
• Industrial Electronics — Suitable for industrial control and equipment that require a polarized aluminum electrolytic solution with endurance at 85°C.
• Chassis-Mounted Power Modules — Snap-in format and radial can package make it appropriate for power modules and assemblies that use board-mounted or chassis-mounted capacitors.

Unique Advantages

• Proven Endurance: 3000 hours rated ripple-current endurance at 85°C provides a clear reliability baseline for long-term operation under load.
• High Ripple-Current Capability: Rated ripple currents (3.8 A at 120 Hz; 4.37 A at 50 kHz) allow designers to manage AC stress on DC rails without overspecifying component count.
• Compact Snap-In Packaging: Radial can with snap-in terminals and small footprint (L: 2.5 × D: 3 cm) helps save board area while enabling secure mechanical retention.
• Wide Ambient Range: −40°C to +85°C operating range supports deployment across varied industrial environments within standard temperature limits.
• Regulatory Ready: RoHS compliance simplifies selection for designs requiring restricted-substance conformance.
