LLS1V183MELB

The LLS1V183MELB is an 18 mF, 35 V aluminum electrolytic capacitor in a snap‑in radial can package designed for general‑purpose power applications. It combines high capacitance and rated ripple capability with a snap‑in terminal form factor for robust board mounting and straightforward installation.

Engineered for continuous operation across an extended temperature range (−40 °C to 85 °C) and specified to withstand 3000 hours of rated ripple current at 85 °C, this part is suitable where long‑life smoothing and bulk energy storage are required.

Key Features

• Capacitance & Voltage: 18 mF nominal capacitance with a 35 V rated voltage and ±20% tolerance for bulk smoothing and decoupling.
• Snap‑in Radial Can Package: Snap‑in terminal type in a radial, can‑snap‑in package case for secure mechanical retention on PCBs.
• High Ripple Current Capability: Rated ripple current of 5.3 A at 120 Hz and 6.095 A at 50 kHz to support high‑stress power rails and filtering tasks.
• Operating Temperature & Lifetime: Specified operation from −40 °C to 85 °C with endurance of 3000 hours at 85 °C under rated ripple conditions.
• Polarized Design: Polarized capacitor suited for DC bias applications requiring electrolytic bulk capacitance.
• Compliance: RoHS compliant (2011/65/EU, (EU)2015/863), meeting current environmental directive requirements.
• Compact Footprint: Package dimensions provided as L: 4.5 × D: 3 cm for mechanical planning and board layout.

Typical Applications

• General‑purpose power filtering: Bulk smoothing and decoupling on DC power rails where 18 mF at 35 V and rated ripple current are required.
• Industrial power supplies: Energy storage and ripple attenuation in industrial converters and control electronics operating within −40 °C to 85 °C.
• UPS and backup circuits: Bulk capacitance for hold‑up and transient support in uninterruptible power supply elements and standby power systems.

Unique Advantages

• Rated for extended ripple life: 3000 hours endurance at 85 °C under rated ripple current provides predictable long‑term performance in sustained operating conditions.
• High ripple handling: Strong ripple current specs at both low and high frequencies help reduce heating and extend service life in high‑stress applications.
• Secure snap‑in mounting: Snap‑in terminals deliver mechanical stability for board‑level assembly and vibration‑resistant installations.
• Wide operating range: −40 °C to 85 °C operation allows deployment across a broad set of environments without derating the component selection.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements for modern electronic assemblies.
