LLS1C183MELZ

The LLS1C183MELZ is an aluminum electrolytic capacitor in a snap‑in terminal, radial can package designed for general‑purpose applications. It delivers high bulk capacitance (18 mF) at a 16 V rated voltage with a compact φ22 × 40 mm form factor and snap‑in mounting for secure board installation.

Engineered for reliability under continuous ripple load, this capacitor is specified for operation from −40°C to 85°C with a rated endurance of 3000 hours at 85°C, making it suitable for designs that require sustained ripple handling and long operational life.

Key Features

• Capacitance & Voltage — 18 mF (18,000 µF) rated at 16 V with ±20% tolerance for bulk energy storage and smoothing in power rails.
• Snap‑In Terminal Package — Radial, can snap‑in mounting simplifies mechanical retention and board assembly for high‑current power modules.
• Endurance at Elevated Temperature — Rated for 3000 hours at 85°C under DC bias plus rated ripple current, providing defined long‑term performance.
• High Ripple Current Capability — Supports 3.98 A at 120 Hz (low frequency) and 4.577 A at 50 kHz (high frequency) to handle substantial AC stress on the capacitor.
• Leakage and Loss Characteristics — Specified leakage current of 1600 µA and tan δ up to 0.50 (measurement frequency 120 Hz at 20°C) for predictable electrical behavior.
• Temperature Range — Operating temperature range from −40°C to 85°C suitable for broad environmental conditions within the specified category.
• Compliance — RoHS‑compliant construction consistent with current directive requirements.
• Packaging — Tray packing for mass production handling and assembly workflows.

Typical Applications

• General Purpose — Bulk Capacitance — Circuits that require 18,000 µF at 16 V for energy storage and voltage stabilization benefit from this capacitor’s high capacitance and tolerance.
• Power Rail Filtering — Boards needing sustained ripple handling can leverage the specified low‑ and high‑frequency ripple current ratings to maintain power integrity.
• Industrial Electronics — Applications with continuous operation at elevated temperatures can use the 3000‑hour endurance rating at 85°C to plan lifecycle and reliability.

Unique Advantages

• High Bulk Capacitance in a Compact Can: 18 mF in a φ22 × 40 mm package delivers large charge storage without excessive PCB area impact.
• Robust Ripple Performance: Rated ripple currents at both low and high frequencies support designs with significant AC stress on DC link or filter stages.
• Defined High‑Temperature Endurance: 3000 hours at 85°C under rated conditions provides clear qualification for long‑term deployment in hot environments.
• Snap‑In Mounting for Secure Assembly: Snap‑in terminals aid mechanical stability and repeatable placement in mass production assembly flows.
• Predictable Electrical Losses and Leakage: Specified tan δ and leakage current values allow accurate margining in power designs and simulations.
• RoHS Compliance: Environmentally compliant materials support regulatory requirements for modern electronics manufacturing.
