LLS1C183MELA

The LLS1C183MELA is an aluminum electrolytic capacitor with snap-in terminals, rated 16 V and 18,000 µF (±20%). It is part of Nichicon’s LLS series and is offered in a radial, can-style snap‑in package sized φ25 × 35L (L: 3.5 × D: 2.5 cm) with tray packing for mass production.

Designed for general‑purpose applications, this capacitor provides high bulk capacitance, substantial ripple-current capability (3.98 A at 120 Hz; 4.577 A at 50 kHz), and a 3,000 hour endurance at 85°C, making it suitable where reliable energy storage and ripple handling are required within an operating range of –40°C to 85°C.

Key Features

• High Capacitance & Rated Voltage — 18,000 µF nominal capacitance at 16 V with ±20% tolerance for bulk energy storage in general‑purpose circuits.
• Ripple Current Performance — Rated ripple current of 3.98 A at 120 Hz and 4.577 A at 50 kHz to support AC ripple and dynamic load conditions.
• Endurance at Elevated Temperature — Specified life of 3,000 hours at 85°C when subjected to rated ripple current, supporting sustained operation at the series’ 85°C standard.
• Electrical Characteristics — tan δ (loss tangent) specified at 0.50 (max.) at 20°C and 120 Hz for the 16 V rating, and leakage current specified at 1,600 µA.
• Robust Operating Range — Operational temperature range from –40°C to +85°C for general‑purpose environments.
• Package & Mounting — Radial, can-style snap‑in terminal type (φ25 × 35L) for secure board mounting; supplied in trays for mass-production handling.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and ripple handling for general-purpose filtering tasks where 16 V, high-capacitance components are required.
• Bulk energy storage in general circuits — Large nominal capacitance (18,000 µF) suited to smoothing and energy buffering in general‑purpose designs.
• Production assemblies — Tray packing and snap‑in radial can package support automated handling and secure mounting for high-volume manufacturing.

Unique Advantages

• Substantial energy density: 18,000 µF at 16 V supplies significant bulk capacitance in a compact φ25 × 35L package.
• Strong ripple-handling capability: Rated for 3.98 A at 120 Hz and 4.577 A at 50 kHz to manage AC ripple across a range of frequencies.
• Durable at rated temperature: 3,000 hour endurance at 85°C with rated ripple current for dependable long-term operation under thermal stress.
• Manufacturing-friendly packaging: Snap‑in terminals and tray packing simplify board mounting and assembly throughput for mass production.
• Clear electrical specs: Specified tan δ (0.50 at 20°C/120 Hz) and defined leakage current (1,600 µA) enable predictable electrical design margins.
• RoHS compliant: Meets environmental restriction requirements for lead-free assemblies.
