LLS1E123MELA

The LLS1E123MELA is a Nichicon LLS series aluminum electrolytic capacitor featuring a snap‑in terminal radial can construction. It provides 12,000 µF of capacitance at a 25 V rating with ±20% tolerance, designed for general‑purpose power applications that require substantial bulk capacitance and robust ripple handling.

Key value propositions include high ripple current capability, a documented 3000‑hour endurance at 85°C, and a compact φ25 × 35 mm snap‑in package suitable for mass production and automated assembly (tray packing).

Key Features

• Capacitance & Voltage — 12,000 µF nominal capacitance at a 25 V rated voltage with ±20% tolerance, providing large bulk energy storage for DC circuits.
• Snap‑In Radial Can Package — Snap‑in terminal mounting simplifies board installation for high‑current and high‑capacitance assemblies; physical size φ25 × 35 mm (L: 3.5 × D: 2.5 cm).
• High Ripple Current Capability — 3.63 A at 120 Hz (low frequency) and 4.175 A at 50 kHz (high frequency), enabling effective AC ripple handling in power rails.
• Endurance at Elevated Temperature — Rated to withstand 3000 hours of rated ripple current at 85°C per LLS series specifications, with post‑test limits of ±20% capacitance change and tan δ within specified bounds.
• Leakage and Dissipation — Specified leakage current 1,640 µA and a dissipation factor (tan δ) of 0.40 maximum measured at 20°C, 120 Hz for the 25 V rating; datasheet provides the standard leakage formula I ≤ 3√(C·V) after initial application.
• Operating Temperature Range — Specified for −40°C to +85°C operation in the LLS series.
• Regulatory & Production Status — RoHS compliant and in mass production; packaged in trays for efficient handling.

Typical Applications

• General‑purpose power systems — Provides bulk capacitance where 12,000 µF and a 25 V rating are required to support DC link and energy buffering needs.
• Bulk energy storage and smoothing — Sized to smooth supply rails and absorb transient currents thanks to high ripple current ratings at both low and high frequencies.
• DC rail filtering — Useful for decoupling and reducing ripple on DC circuits within the −40°C to +85°C operating range.

Unique Advantages

• High ripple handling: Rated ripple currents of 3.63 A (120 Hz) and 4.175 A (50 kHz) enable reliable ripple suppression across common power frequencies.
• Documented 3000‑hour endurance: Endurance specification at 85°C provides predictable long‑term performance with defined post‑test limits for capacitance, tan δ and leakage.
• Compact, assembly‑friendly form factor: φ25 × 35 mm snap‑in can in tray packing supports automated board mounting and efficient production workflows.
• Clear electrical parameters: Specified tan δ (0.40 at 20°C/120 Hz), leakage current (1,640 µA), and tolerance (±20%) facilitate straightforward design margining.
• RoHS compliant and production ready: Meets RoHS requirements and is available in mass production quantities for volume designs.
