LLS1E183MELA

The LLS1E183MELA is an aluminum electrolytic capacitor in a snap‑in terminal radial can designed for general‑purpose electronic equipment. It provides 18 mF capacitance at a 25 V rating and is specified for operation from −40 °C to +85 °C.

Engineered for power filtering and bulk energy storage in board‑level applications, this snap‑in capacitor delivers long endurance under rated ripple current and meets RoHS (2011/65/EU, (EU)2015/863) requirements.

Key Features

• Capacitance and Voltage — 18 mF capacitance with a 25 V rated voltage and ±20% tolerance, offering substantial bulk capacitance for smoothing and energy storage.
• Snap‑In Radial Can Package — Snap‑in terminal, radial can package for secure, board‑level mounting in power assemblies.
• Operating Temperature Range — Rated for operation from −40 °C to +85 °C for use across typical industrial and commercial environments.
• Endurance under Ripple Current — Withstands 3000 hours application of rated ripple current at 85 °C; endurance criteria include capacitance change within ±20% and leakage current not exceeding initial specified value after the test.
• Ripple Current Ratings — Specified ripple current of 4.68 A at 120 Hz and 5.382 A at 50 kHz, supporting AC superposition and high‑frequency ripple environments.
• Leakage Current Characteristic — Leakage current meets I ≤ 3√CV (μA) after 5 minutes’ application of rated voltage at 20 °C, where C is capacitance (μF) and V is voltage (V).
• RoHS Compliance — Constructed in accordance with the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Dimensions — Compact can dimensions: length 4.5 cm × diameter 2.5 cm; maximum seated height 1.772 inch, suitable for many power module footprints.

Typical Applications

• General‑Purpose Power Filtering — Bulk capacitance for smoothing DC rails and reducing ripple in power supplies within the specified voltage and temperature limits.
• Board‑Level Energy Storage — Provides local energy reservoir for transient load demands in industrial and commercial electronic assemblies.
• Power Conversion Modules — Suitable for use in power conversion and regulation circuits where snap‑in mounting and sustained ripple endurance are required.

Unique Advantages

• Proven Endurance: Specified to withstand 3000 hours of rated ripple current at 85 °C, helping ensure long operating life under continuous ripple stress.
• High Ripple Capability: Defined ripple current ratings at both 120 Hz (4.68 A) and 50 kHz (5.382 A) support a range of low‑ and high‑frequency applications.
• Robust Temperature Range: −40 °C to +85 °C operating range enables deployment in diverse environmental conditions.
• Secure Snap‑In Mounting: Snap‑in radial can package simplifies installation and mechanical retention on power PCBs.
• Regulatory Compliance: RoHS‑compliant construction supports environmentally conscious designs and regulatory needs.
