Part Number: LMH5485-SEP
Other Parts Discussed in Thread: LM6172QML-SP,

Hi Team,

My customer is interested in using LMH5485DGKSEP, do we have the more information on the engineering models and flight models for this part?

Best Regards,

Ernest

    Hello Ernest,

      Do they need the engineering model for testing/prototyping? Then, is the customer looking to use the full space qualification for this part? I want to clarify the difference between the two: for example, the LM6172QML-SP has a QMLV option and a EM option. The difference is the full QMLV is qualified as radiation hardened assured and the engineering model is not. 

    Thank you,
    Sima

    Yes, customer needs the engineering model for testing/prototyping,

    They are actually after the LMH5485-SEP, which does not have a rad-hard version at this time.  do we have the more information on the engineering models and flight models for this part?

    Hello Ernest,

    I believe we should be able to provide one, but still unsure. I am looking into this with our team. I’ll be able to update you by Friday MST. 

    Thank you,

    Sima

    Hello Ernest,

         I talked to our systems engineer and mentioned that engineering models (EM) are units intended for engineering evaluation only. They are processed to a noncompliant flow. These units are not suitable for qualification, production, radiation testing or flight use. Parts are not warranted for performance over the full MIL specified temperature range of –55°C to 125°C or operating life. However, SP and SEP rated devices are radiation qualified and hardened, but at different radiation levels. 

       None of any -SEP amplifiers currently have an engineering model. Our team included, and have not planned to release engineering/flight models. However, we can discuss this further offline over email. I will contact you with a discussion between our space marketing/system experts. 

    Thank you,
    Sima
