LLS1C273MELA

The LLS1C273MELA is a snap‑in aluminum electrolytic capacitor in Nichicon's LLS series, offering 27,000 µF capacitance at a 16 V rating in a compact radial can (φ25 × 45 mm). Designed for general‑purpose power applications, it provides bulk energy storage and smoothing with robust ripple handling and extended endurance.

Key value propositions include high bulk capacitance in a snap‑in package, sustained ripple current capability at 85°C, and a 3,000‑hour rated endurance that supports continuous operation in industrial and power electronics environments.

Key Features

• Capacitance & Voltage: 27,000 µF nominal capacitance at a rated voltage of 16 V, suitable for high‑capacity bulk energy storage and smoothing.
• Package & Mounting: Radial snap‑in can (φ25 × 45 mm) for secure vertical mounting and straightforward PCB insertion and retention.
• Endurance & Reliability: Rated for 3,000 hours at 85°C while withstanding rated ripple current, supporting prolonged operation under elevated temperature and load.
• Ripple Current Performance: Low‑frequency ripple current 4.98 A (120 Hz) and high‑frequency ripple current 5.727 A (50 kHz), enabling effective filtering across a range of operating frequencies.
• Electrical Characteristics: Loss tangent (tan δ) 0.50 at 20°C, 120 Hz and a measured leakage current value of 1,970 µA consistent with series specifications.
• Operating Range & Compliance: Rated for −40°C to +85°C operation and RoHS compliant; supplied in tray packing and available in mass production quantities.

Typical Applications

• General‑purpose power systems: Bulk decoupling and smoothing where high capacitance and sustained ripple current at elevated temperature are required.
• Industrial power electronics: Energy storage and filtering in equipment that benefits from long endurance at 85°C and snap‑in mechanical retention.
• Power supply modules: Input/output filtering and hold‑up functions where large capacitance (27,000 µF) and reliable ripple handling improve voltage stability.

Unique Advantages

• High bulk capacitance in a compact form: 27,000 µF in a φ25 × 45 mm can reduces board area for equivalent energy storage.
• Sustained ripple capability: Specified ripple currents at both 120 Hz and 50 kHz support effective filtering across low and high frequency components.
• Long rated life at elevated temperature: 3,000 hours endurance at 85°C provides predictable performance for continuous operation.
• Snap‑in mounting for secure retention: Radial, snap‑in terminals simplify assembly and provide robust mechanical stability on the PCB.
• Measured electrical control: Specified tan δ and leakage current values aid in thermal and loss budgeting during design.
• Regulatory compliance and availability: RoHS compliant and listed as mass production, facilitating procurement and regulatory alignment.
