Do you need a lot of design and development resources to select inductors for Bias-T circuits?

• 
  Increasing importance of high-speed for automotive
• 
  Components selection expertise to confirm criteria values
• 
  A circuit configuration combining multiple inductors is required

Impact of increasingly present high-speed automotive networks

Numerous cameras and sensors are installed in automobiles to improve functionality, such as self-driving and ADAS. As a result, high-speed automotive networks are increasingly important for transferring the information detected by these cameras and sensors to ECUs.
Adoption of PoC (Power Over Coaxial) is advancing as a high-speed transfer method that performs the transfer with a single coaxial cable by superimposing the power onto the data transfer interface.

Required expertise and time to clear standards

Troublesome components selection is performed automatically, helping to reduce the needed design resources!

Main features of the Bias-T Inductor Selection Tool

• Combinations of components that clear the target criteria can be identified just by making simple condition settings.
• By uploading specific criteria values, combinations of components that clear those criteria can be selected.
• By making more detailed settings such as the board information, simulations can be performed having greater consistency with actual measurements.
• Selections that take into account Murata's design research knowledge can be proposed.

Simple operations increase efficiency

The Bias-T Inductor Selection Toolproposes the optimal combination of PoC bias inductors including part numbers just by making simple settings in 3 steps.
