Overview of LLS1C183MELB – Snap‑in Aluminum Electrolytic Capacitor, 18,000 µF, 16 V

The LLS1C183MELB is an aluminum electrolytic, snap‑in terminal capacitor engineered for general‑purpose applications requiring large capacitance at low DC voltage. It is a radial, can‑style snap‑in device rated for 16 V with 18,000 µF nominal capacitance and a ±20% tolerance.

Designed for board‑level bulk energy storage and filtering in mass production environments, the LLS1C183MELB combines high capacitance, snap‑in mounting, and a standard 85°C operating range to support stable operation in a wide range of general‑purpose equipment.

Key Features

  • High Capacitance, Low Voltage  18,000 µF nominal capacitance at a 16 V rated voltage provides substantial bulk storage for low‑voltage power rails.
  • Snap‑In Radial Can Package  Snap‑in terminal mounting and radial can construction (φ30 × 30 mm / L: 3 cm × D: 3 cm) simplify PCB installation and mechanical retention for production assembly.
  • Operating Temperature Range  Specified for −40°C to +85°C to accommodate typical ambient conditions for general‑purpose electronics.
  • Endurance at Elevated Temperature  Withstands 3,000 hours of rated ripple current at 85°C, providing verified life performance under sustained thermal and electrical stress.
  • Polarized Construction  Polarized electrolytic design suitable for DC applications where polarity is observed.
  • Ripple Current Capability  Rated ripple current of 3.88 A at 120 Hz and 4.462 A at 50 kHz to support filtering and smoothing under AC ripple conditions.
  • Leakage and Loss Characteristics  Leakage current specification follows I ≤ 3√(C·V) μA after standard voltage application; tangent of loss angle (tan δ) for 16 V units is specified (max. 0.50), supporting predictable AC behavior.
  • RoHS Compliant  Conforms to RoHS directive requirements for lead‑free material compliance.
  • Production‑Oriented Packaging  Tray packing suitable for mass production handling and assembly processes.

Typical Applications

  • General‑Purpose Power Filtering  Bulk capacitance for smoothing and decoupling on low‑voltage DC rails where 18,000 µF at 16 V is required.
  • Board‑Level Energy Reserve  Snap‑in mounting provides reliable mechanical retention for applications needing local energy storage on PCBs.
  • Production Assemblies  Tray packing and snap‑in terminals support high‑volume assembly workflows for general‑purpose electronic equipment.

Unique Advantages

  • Large Bulk Capacitance in a Compact Can  18,000 µF nominal capacitance delivers substantial energy storage while occupying a φ30 × 30 mm footprint.
  • Verified Thermal Endurance  Rated to endure 3,000 hours at 85°C with rated ripple current, giving designers measurable longevity data for thermal stress planning.
  • Clear Electrical Specifications  Defined ripple current values at 120 Hz and 50 kHz and leakage current limits provide predictable behavior in power‑conditioning roles.
  • Assembly‑Friendly Mounting and Packaging  Snap‑in terminals and tray packing enable straightforward insertion and handling for automated or manual production lines.
  • Regulatory Compliance  RoHS compliance supports deployment in products requiring restricted‑substance adherence.
