LLS2A182MELA

The LLS2A182MELA is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LLS series. It delivers 1.8 mF (1800 µF) capacitance at a 100 V rated voltage in a radial, snap‑in can package intended for general-purpose power applications.

Designed for sustained operation up to 85°C, the device combines high ripple-current capability with a 3000‑hour endurance at 85°C, making it suitable for power filtering, bulk energy storage and other general-purpose power-electronics roles where a 100 V snap‑in capacitor is required.

Key Features

• Capacitance and Voltage — 1.8 mF (1800 µF) nominal capacitance with a 100 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Snap‑in Radial Can Package — Snap‑in terminal mounting for secure mechanical retention and straightforward board or chassis installation; package form factor listed as φ25×35L (L: 3.5 × D: 2.5 cm).
• Ripple‑Current Performance — 2810 mA low‑frequency ripple current at 120 Hz and 3231.5 mA high‑frequency ripple current at 50 kHz, supporting demanding AC stress in power circuits.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) specified at 0.20 max (measured at 120 Hz, 20°C) and leakage current of 1270 µA, enabling predictable impedance and leakage behavior.
• Thermal and Endurance Rating — Operating temperature range −40°C to +85°C with an endurance rating of 3000 hours at 85°C when subjected to rated ripple and DC bias per datasheet conditions.
• Compliance and Production — RoHS compliant, supplied in tray packing and available in mass production quantities.

Typical Applications

• Power Filtering and Bulk Storage — Bulk energy storage and smoothing in power supplies where a 100 V, 1800 µF capacitor is required to handle ripple current loads.
• Industrial Power Electronics — General-purpose use in industrial power modules and control systems that require sustained ripple current capability and a rugged snap-in mounting.
• Commercial Equipment — Power conditioning and decoupling in commercial electronic equipment operating within −40°C to +85°C and requiring extended endurance at elevated temperature.

Unique Advantages

• High Sustained Ripple Capability — Rated ripple currents of 2.81 A (120 Hz) and 3.2315 A (50 kHz) allow the capacitor to support continuous AC stress typical of power conversion circuits.
• Long Endurance at Elevated Temperature — 3000 hours endurance at 85°C under rated conditions delivers predictable lifetime behavior for designs exposed to sustained heat and load.
• Compact Snap‑in Form Factor — φ25×35L radial can with snap‑in terminals provides a space-efficient solution with secure mounting for chassis or board installations.
• Predictable Electrical Characteristics — Specified tan δ (0.20 max at 120 Hz, 20°C) and defined leakage current support reliable impedance and leakage planning in design calculations.
• Regulatory Compliance and Production Readiness — RoHS compliance and tray packing with mass production availability simplify procurement and regulatory documentation.
