LM34: LM34CAZ, Failed resistance test - Low resistance

Part Number: LM34

Tool/software:

Hi engineer

can you help me ? we purchased 1000pcs from TI store. test 1000pcs, 6 pcs indicated low resistance. 

Issue:
Failed resistance test - Low resistance
Specification: 65 to 85 kohms

Failure Analysis:
1) Replaced the wire and check the resistance but still out of specs. (indicated 47kohms)
2) Replace the IC and resistance test passed. Affected PN# LM34CAZ/NOPB

  • Joyce,

    What exactly is the test here? Between what two pins are you getting a low resistance failure? Between pins of the LM34? Even when the resistance test fails, do the 6 ICs function normally?

    Regards
