LLS1E153MELA

The LLS1E153MELA is a snap‑in terminal aluminum electrolytic capacitor in Nichicon’s LLS series, offering 15,000 µF capacitance at a 25 V rating with a ±20% tolerance. It is designed for general‑purpose applications where substantial bulk capacitance and sustained ripple current capability are required.

Key attributes include a rugged snap‑in can package (radial, snap‑in), RoHS compliance, tray packing for production handling, and a rated operating temperature range of −40°C to +85°C with a 3,000‑hour endurance at 85°C.

Key Features

• Capacitance & Voltage — 15,000 µF (15 mF) rated at 25 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Snap‑in Package — Radial, can‑style snap‑in terminals for efficient PCB mounting and mechanical stability in high‑capacitance applications.
• Ripple Current Performance — Low‑frequency ripple current of 4.10 A at 120 Hz and high‑frequency ripple current of 4.715 A at 50 kHz, supported under the LLS series endurance specification.
• Loss Tangent (tan δ) — tan δ max of 0.40 at 20°C and 120 Hz for the 25 V rating, enabling predictable AC‑loss characteristics.
• Leakage Current — Specified leakage current of 1,830 µA after standard conditioning.
• Reliability & Lifetime — Rated to withstand 3,000 hours with rated ripple current at 85°C (LLS series endurance specification).
• Environmental Compliance & Packaging — RoHS‑compliant and supplied in tray packing suitable for volume production.
• Operating Range & Physical Size — Operating temperature −40°C to +85°C; nominal size φ25 × 40 mm (L: 4 × D: 2.5 cm).

Typical Applications

• General‑Purpose Power Electronics — Bulk energy storage and decoupling in general‑purpose power circuits where high capacitance and sustained ripple handling are needed.
• Power Supply Filtering — Smoothing and ripple attenuation in supplies that require long endurance at elevated temperature (3,000 h at 85°C) and specified ripple current capability.
• Industrial Electronics — Applications that demand robust, tray‑packed components for production assembly and reliable performance across −40°C to +85°C.

Unique Advantages

• High Bulk Capacitance: 15,000 µF provides substantial energy storage for systems needing large charge reservoirs without adding multiple smaller capacitors.
• Sustained Ripple Endurance: Specified ripple current ratings (4.10 A at 120 Hz, 4.715 A at 50 kHz) and 3,000‑hour endurance at 85°C support continuous operation under ripple stress.
• Predictable AC Losses: tan δ = 0.40 (25 V, 120 Hz, 20°C) gives designers a defined leakage‑loss parameter for thermal and efficiency calculations.
• Production‑Friendly Packaging: Tray packing and snap‑in terminals simplify handling and PCB assembly in mass production environments.
• Wide Operating Temperature: −40°C to +85°C range covers a broad set of general‑purpose industrial and commercial applications.
• Regulatory Compliance: RoHS‑compliant construction supports regulatory requirements for many markets and assemblies.
