Hi,

Good Day.

We understand the suffix letter "B" was dropped from the product name but this is still meet MIL-STD "CLASS B COMPLIANT"?

Please advise. Thank you very much.

Best Regards,

Ray Vincent

    Hi Ray,

    The letter "B" in the product name, such as LM117H/883B goes back a couple of decades.  Back then, the mil standards required the current revision letter of 883 be included in the product name.  That requirement ceased with rev. C and hasn't been done in decades.

    The LM117x/883 products are manufactured, tested and qualified to the mil class Q flow MIL-PRF-38535 and MIL-STD-883.  Class Q has replaced Class B.
