LLS2E271MELY

The LLS2E271MELY is a Nichicon LLS series aluminum electrolytic capacitor with a snap‑in terminal configuration, rated 270 µF at 250 V. Designed for general‑purpose power applications, it delivers measured low loss (tan δ) and defined ripple performance across low and high frequencies.

Key engineering attributes include snap‑in mounting for secure panel or chassis installation, 3000 hours endurance at 85°C, RoHS compliance, and mass production availability with tray packing for predictable supply chain handling.

Key Features

• Electrical Capacity & Voltage — 270 µF capacitance with a 250 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low Loss Factor — tan δ specified at 0.15 (measurement at 120 Hz, 20°C), supporting efficient energy storage with controlled dissipation.
• Ripple Current Capability — 1.42 A at 120 Hz (low frequency) and 2.13 A at 50 kHz (high frequency) to support ripple handling in both mains‑frequency and higher‑frequency systems.
• Leakage Current — Specified leakage current of 770 µA, providing predictable DC leakage characteristics for design margin calculations.
• Endurance — Rated for 3000 hours at 85°C under DC bias plus rated ripple current, with defined limits on capacitance change, tan δ, and leakage after the test.
• Mechanical & Mounting — Snap‑in (radial can) package, polarized, with a compact φ20 × 30 mm can size and tray packing for production handling.
• Operating Range & Compliance — Operating temperature range from −40°C to +85°C and RoHS‑compliant construction.

Typical Applications

• General‑purpose power systems — Bulk energy storage and smoothing in general‑purpose power circuits that require a 250 V, 270 µF capacitor with defined ripple handling.
• Industrial power electronics — Use where elevated ripple capability and a 3000‑hour 85°C endurance profile are required for sustained operation.
• Chassis or panel mount assemblies — Snap‑in terminal configuration enables secure mounting in systems that use radial can capacitors in tray‑based production.

Unique Advantages

• Defined ripple performance across frequencies — Explicit ripple current ratings at both 120 Hz (1.42 A) and 50 kHz (2.13 A) allow predictable thermal and filtering design.
• Long endurance at elevated temperature — 3000 hours at 85°C under rated conditions provides a measurable reliability baseline for long‑life designs.
• Low loss characteristic — tan δ of 0.15 (120 Hz, 20°C) reduces dissipation compared with higher loss parts, aiding thermal management.
• Compact snap‑in package — φ20 × 30 mm radial can with snap‑in terminals for secure mechanical mounting and efficient PCB or chassis layout.
• Predictable leakage — Specified leakage current (770 µA) supports accurate power‑budget and standby loss calculations.
• Production readiness — Mass production status and tray packing streamline procurement and assembly for volume builds.
