  • Efficiency - dBA

    Efficiency - dBA is a parameter that measures the efficiency of an electronic component while taking into account the level of noise or sound it produces during operation. The "dBA" unit signifies that the measurement is weighted to reflect the sensitivity of the human ear to different frequencies of sound. In electronic components, such as fans or power supplies, efficiency is crucial for determining how effectively the component converts input power into useful output power, while the dBA aspect indicates the level of noise generated during this process. A higher efficiency rating with a lower dBA value is generally preferred as it signifies that the component is operating efficiently while producing minimal noise.

  • Efficiency - Type

    Efficiency - Type in electronic components refers to the type of efficiency measurement associated with the component's performance. Efficiency is a crucial parameter that indicates how well a component converts input energy into useful output energy. The type of efficiency measurement can vary depending on the specific component, such as power efficiency for power supplies or energy efficiency for lighting devices. Understanding the efficiency type of an electronic component is essential for evaluating its overall performance and determining its suitability for a particular application.

    Sensitivity
  • Height Seated (Max)

    Height Seated (Max) is a parameter in electronic components that refers to the maximum allowable height of the component when it is properly seated or installed on a circuit board or within an enclosure. This specification is crucial for ensuring proper fit and alignment within the overall system design. Exceeding the maximum seated height can lead to mechanical interference, electrical shorts, or other issues that may impact the performance and reliability of the electronic device. Manufacturers provide this information to help designers and engineers select components that will fit within the designated space and function correctly in the intended application.
