LLS1E822MELA

The LLS1E822MELA is an aluminum electrolytic capacitor in a snap‑in terminal (radial can) package, rated for 8.2 mF at 25 V with ±20% tolerance. It is an 85°C standard device designed for general‑purpose applications where bulk capacitance and sustained ripple endurance are required.

Key characteristics include a rated operating temperature range of −40°C to +85°C, RoHS compliance, and endurance under rated ripple current for 3000 hours at 85°C—providing predictable electrical behavior in temperature‑constrained environments.

Key Features

• Capacitance & Voltage — 8.2 mF rated capacitance at 25 V with ±20% tolerance (measured at 120 Hz, 20°C), delivering substantial bulk storage for DC link and smoothing applications.
• Snap‑in Radial Package — Snap‑in terminal (radial, can – snap‑in) mounting for secure through‑hole installation and robust mechanical retention.
• High Ripple Endurance — Specified to withstand rated ripple current for 3000 hours at 85°C. Rated ripple currents for this part are 2.78 A at 120 Hz and 3.197 A at 50 kHz.
• Temperature Range — Operating temperature range from −40°C to +85°C, suitable for designs requiring wide ambient tolerance.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) max. 0.40 at 25 V (120 Hz, 20°C); leakage current defined by I ≤ 3√CV (μA) after 5 minutes’ application of rated voltage at 20°C.
• Reliability & Endurance Specs — After DC bias plus rated ripple current for 3000 hours at 85°C, capacitance change remains within ±20% of initial value and leakage current remains at or below initial specified levels, per the product series endurance requirements.
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint — Package dimensions approximately 2.5 × 2.5 cm, supporting space‑efficient power designs.

Typical Applications

• General‑purpose power electronics — Bulk energy storage and smoothing where 8.2 mF at 25 V and multi‑amp ripple capability are required.
• Power supply filter stages — Use for DC link filtering and ripple reduction leveraging the component’s specified ripple current and endurance at 85°C.
• Industrial and commercial equipment — Through‑hole snap‑in mounting and wide operating temperature range suit assemblies that need mechanically robust bulk capacitance solutions.

Unique Advantages

• Long ripple life under heat — Rated to withstand 3000 hours of rated ripple current at 85°C, supporting stable long‑term performance in warm operating conditions.
• Measurable electrical limits — Clear specifications for tan δ, leakage current formula, and endurance criteria allow engineers to model performance precisely.
• High ripple capacity across frequencies — Provided ripple current ratings at 120 Hz and 50 kHz help address applications with low‑ and high‑frequency ripple components.
• Through‑hole, robust mounting — Snap‑in radial can packaging provides secure mechanical retention for power modules and heavy‑vibration environments.
• Regulatory compliance — RoHS conformity for designs needing restricted‑substance compliance.

Why Choose LLS1E822MELA?

The LLS1E822MELA positions itself as a reliable, specification‑driven bulk capacitance component for designers who need quantifiable ripple endurance, stable behavior at up to 85°C, and a secure snap‑in through‑hole package. Its clearly defined electrical characteristics—capacitance, tolerance, tan δ, leakage current formula, and ripple ratings—make it straightforward to integrate into power supplies and general‑purpose equipment where predictable aging and endurance are important.

This part is suited to engineers specifying robust bulk capacitors for medium‑voltage DC systems (25 V rated), assemblies requiring through‑hole retention, and designs that prioritize verifiable endurance data and RoHS compliance.
