LLS2A182MELB

The LLS2A182MELB is a snap‑in terminal aluminum electrolytic capacitor engineered for general-purpose power applications. It delivers 1,800 µF at a 100 V rating with snap‑in radial can packaging and tray packing for mass production.

Designed for high ripple environments and sustained operation, this capacitor combines high ripple current capability with a 3,000‑hour endurance at 85°C, making it suitable for industrial and power‑conversion designs requiring reliable bulk capacitance and long life.

Key Features

• Capacitance & Voltage: 1.8 mF (1,800 µF) rated at 100 V with ±20% tolerance (measured at 120 Hz, 20°C), providing substantial bulk energy storage for DC link and smoothing applications.
• High Ripple Current Handling: 2,650 mA at 120 Hz (low frequency) and 3,047.5 mA at 50 kHz (high frequency), supporting demanding ripple and switching conditions.
• Endurance & Reliability: Specified for 3,000 hours at 85°C with DC bias plus rated ripple current; capacitance change remains within ±20% and leakage current stays below initial specified value after the endurance test.
• Loss Characteristics: tan δ (DF) of 0.2 maximum at 20°C, 120 Hz for the 100 V rating, helping to characterize ESR behavior under operating conditions.
• Leakage Current: Rated leakage current of 1,270 µA (measured after 5 minutes at 20°C under rated voltage conditions compliant with datasheet leakage definition).
• Package & Mounting: Snap‑in radial can (φ30 × 25 mm length) for secure panel or chassis mounting and efficient assembly in high-volume production (tray packing).
• Operating Environment: Category temperature range –40°C to +85°C and RoHS‑compliant construction for broad environmental compatibility and regulatory conformance.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and energy storage for switched‑mode power supplies and power conversion systems that require sustained ripple handling and long life.
• Motor Drives and Inverters: DC link and smoothing duties in motor controllers and inverter stages where high ripple current capability and 100 V rating are required.
• Power Conditioning & Filtering: Filter and decoupling applications in racks and cabinets where snap‑in mounting and tray packing support robust assembly and serviceability.
• General Purpose Electronics: Designs needing reliable large‑value capacitance for voltage stabilization in industrial and commercial equipment.

Unique Advantages

• High ripple tolerance: Dual ripple current ratings (2.65 A at 120 Hz and 3.0475 A at 50 kHz) enable use across a wide range of switching frequencies.
• Long‑term endurance: 3,000 hours at 85°C under rated ripple and DC bias provides predictable life performance for sustained operation.
• Low dissipation factor: tan δ ≤ 0.2 at 20°C, 120 Hz for the 100 V version helps manage losses and thermal rise in high‑duty applications.
• Robust mounting: Snap‑in radial can construction offers secure mechanical retention for cabinet and chassis installations.
• Wide temperature range: –40°C to +85°C operation supports deployment in varied environmental conditions encountered in industrial equipment.
• Regulatory compliance: RoHS‑compliant materials support regulatory and environmental requirements for commercial and industrial products.
