Overview of LLS1H183MELC – Aluminum Electrolytic Snap‑In Capacitor, 50 V, 18 mF

The LLS1H183MELC is an aluminum electrolytic capacitor in a radial, snap‑in can package, manufactured by Nichicon. It delivers 18 mF of capacitance at a rated voltage of 50 V and is polarized for DC applications.

Designed for general‑purpose electronic applications, this snap‑in terminal capacitor is specified for an operating temperature range of −40 °C to 85 °C and is RoHS compliant. It is constructed to withstand 3000 hours of rated ripple‑current application at 85 °C, providing predictable endurance in designs that require sustained ripple handling.

Key Features

  • Electrical — Capacitance & Voltage  Provides 18 mF capacitance at a rated voltage of 50 V with a tolerance of −20% to +20%.
  • High ripple current capability  Rated ripple current: 7.14 A at 120 Hz and 8.211 A at 50 kHz, supporting sustained AC stress under rated conditions.
  • Endurance at temperature  Specified to withstand 3000 hours of rated ripple current application at 85 °C per the product series endurance test.
  • Operating temperature  Operates across −40 °C to 85 °C.
  • Mounting & package  Snap‑in terminal, radial can package for snap‑in PCB mounting; physical size approximately L: 5 × D: 3.5 cm, with a seated height up to 1.969 inches.
  • Polarized design  Electrolytic, polarized capacitor suitable for DC bias applications.
  • Regulatory status  Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

  • General‑purpose electronics  For designs that require a polarized aluminum electrolytic capacitor with 18 mF at 50 V and snap‑in mounting.
  • Power modules and supplies  Used where sustained ripple current capability and 85 °C endurance are required in a snap‑in radial can form factor.
  • Industrial equipment  Applicable to general‑purpose industrial designs within the specified −40 °C to 85 °C operating range.

Unique Advantages

  • Long ripple endurance  Engineered to withstand 3000 hours of rated ripple‑current application at 85 °C, supporting durability under sustained AC stress.
  • High ripple current ratings  Specified ripple currents of 7.14 A (120 Hz) and 8.211 A (50 kHz) provide clear performance metrics for thermal and ripple budgeting.
  • Robust temperature range  Rated for operation from −40 °C to 85 °C to accommodate a wide range of environmental conditions.
  • Snap‑in radial can package  Snap‑in terminals simplify board installation for applications preferring radial, secured mounting.
  • Clear electrical specification  18 mF at 50 V with ±20% tolerance and polarized construction allow straightforward selection and design integration.
  • RoHS compliance  Meets RoHS directive requirements for regulatory-aligned designs.
