I needed some LM’s in a TO3 case for a project. An error occurred the product could not be saved. Anybody know why the steel case is so expensive.


What application would require a steel case that aluminum wouldn’t work? If you find a lj317 of interest without a calibration version, our customer support will be more then helpful to clarify this topic for you.

Aluminum has higher thermal conductivity than steel, so I’d bet it’s a Mil spec for ruggedness.

Why is the LM TO-3 steel case so expensive?

To-3 are becoming more of an obsolete package. Products The range of this service include, but not limited to: Thank you for your message. I don’t think its a TO3 quantity issue.

The one I used was rated for I suspect most TO-3 business is not for new designs but repair parts, crazy expensive military, etc. After the order has been placed for the calibrated version, the non-calibrated device will be sent out from lm137 warehouse to the calibration institute of Intertek Calibration service in process at Intertek Creating the certificate for end user The device will be repacked and sent directly to the end user. Circuit Operation L1 is a to 24 volt transformer.

The published spec’s are the same Temp, current, ect. The answer for both topic is yes. D1 could also be four 3 amp diodes. to
