    Thermal Resistance of BMA400

    Thermal Resistance of BMA400

    Hello, 

    as other members asked for different sensors before I need the thermal parameters for the BMA400 and its LGA12 package.

    What I miss in the datasheet is the 

    Junction to case: θ JC =  ?? °C/W
    Junction to ambient: θ JA =  ?? °C/W

    values of the package that are normally available for electronic components. 

    I need these values to calculate the maximum temperature of the component in case of internal failure depending on the power our circuit can provide.

    Thank you very much for your help!

    Hi

    We have designed this part into a product, and we also need this same information for ATEX compliance assessment. Happy to sign an NDA. but surely a deg C per watt per figure is hardly going to be a huge trade secret? You have given figures for other devices...
