LLS1E273MELC

The LLS1E273MELC is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LLS series. It delivers 27 mF capacitance at a rated 25 V in a radial, can‑style snap‑in package designed for general‑purpose electronic use.

Engineered for sustained ripple performance, this component withstands 3000 hours of application of rated ripple current at 85°C and is RoHS compliant, making it suitable for a range of general‑purpose power and electronic equipment designs.

Key Features

• Capacitance & Voltage — 27 mF nominal capacitance with a rated voltage of 25 V and ±20% tolerance at 120 Hz, 20°C.
• Ripple Endurance — Specified to withstand 3000 hours of rated ripple current application at 85°C; endurance limits include capacitance change within ±20% and leakage current less than or equal to initial specified value after the test.
• High Ripple Current Capability — Ripple current handling of 6.02 A at 120 Hz and 6.923 A at 50 kHz, supporting demanding AC ripple conditions within its ratings.
• Operating Temperature Range — Rated for –40°C to +85°C operation (for the 25 V rating), suitable for a wide range of ambient environments listed for the series.
• Loss Characteristics — Tangent of loss angle (tan δ) maximum for 25 V is 0.40 (measured at 120 Hz, 20°C), providing a quantified dissipation metric for design calculations.
• Leakage Current Specification — Leakage current meets I ≤ 3√CV (µA) after 5 minutes application of rated voltage at 20°C (C: µF, V: V), enabling predictable DC leakage behavior.
• Packaging & Mounting — Radial, can‑style snap‑in package with snap‑in terminals for robust mechanical mounting in chassis or assemblies; polarized design.
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size — Dimension: L: 4 × D: 3.5 cm, providing a compact footprint for its capacitance and current handling.

Typical Applications

• General‑purpose power filtering — Bulk capacitance and rated ripple endurance make this part suitable where stable smoothing and ripple management are required in general electronic equipment.
• Power management modules — High ripple current capability supports use in power supply stages and other general‑purpose power circuits operating at or below the 25 V rating.
• Industrial and commercial electronics — The –40°C to +85°C operating range and snap‑in mounting suit typical general‑purpose assemblies and equipment enclosures.

Unique Advantages

• Sustained ripple endurance: 3000 hours rated ripple application at 85°C provides measurable long‑term performance for continuous or repeated ripple stress.
• High ripple current handling: Specified ripple currents at both low and higher frequencies (6.02 A @ 120 Hz, 6.923 A @ 50 kHz) support diverse switching and line conditions.
• Predictable electrical parameters: Defined tan δ and leakage current limits enable reliable thermal and leakage budgeting in designs.
• Robust mounting: Snap‑in radial can reduces assembly complexity while offering secure mechanical attachment for general‑purpose equipment.
• RoHS compliance: Meets applicable RoHS directives for use in regulated markets and products.
