LLS1E183MELC

The LLS1E183MELC is an aluminum electrolytic capacitor in a snap‑in terminal can designed for general‑purpose electronic equipment. It delivers 18,000 µF of capacitance at a 25 V rating with polarized construction and tray packing for board‑level assembly.

Engineered for sustained ripple operation, this part is specified for operation from −40°C to 85°C and is rated for 3,000 hours endurance at 85°C, providing stable performance where extended ripple handling and bulk capacitance are required.

Key Features

• High Capacitance: 18,000 µF (18 mF) nominal capacitance for bulk energy storage and smoothing in general‑purpose circuits.
• Rated Voltage and Tolerance: 25 V rated voltage with ±20% capacitance tolerance at 120 Hz, 20°C.
• Ripple Current Endurance: Low frequency ripple current 4.68 A at 120 Hz and high frequency ripple current 5.382 A at 50 kHz, withstanding rated ripple current application for 3,000 hours at 85°C.
• Leakage Current: Specified leakage current of 2,010 µA after rated voltage application.
• Temperature Range and Life: Operating temperature −40°C to 85°C with a 3,000‑hour endurance rating at 85°C.
• Mounting and Package: Snap‑in terminal (radial, can – snap‑in) for secure board attachment; supplied in tray packing.
• RoHS Compliance: Conforms to RoHS directives as specified in the product series documentation.

Typical Applications

• General‑purpose electronic equipment: Provides large bulk capacitance where robust ripple handling and long endurance at elevated temperatures are required.
• Board‑level bulk energy storage: Snap‑in mounting offers secure mechanical retention for board assemblies that need sustained capacitance.
• Ripple smoothing and decoupling: Rated ripple current values support applications that require continuous AC ripple handling over extended life at 85°C.

Unique Advantages

• Substantial capacitance in a compact can: 18,000 µF in a φ35 × 30 mm package delivers significant energy storage without requiring large footprints.
• Proven ripple endurance: Specified to withstand 3,000 hours of rated ripple current at 85°C, supporting long‑life operation under continuous ripple stress.
• High ripple current capability: Both low‑ and high‑frequency ripple current ratings (4.68 A @120 Hz, 5.382 A @50 kHz) enable versatility across differing ripple environments.
• Secure snap‑in mounting: Snap‑in terminals provide reliable board retention for radial can installations and ease of assembly with tray packing.
• Regulatory compliance: RoHS‑compliant construction aligns with common environmental and manufacturing requirements.
