Total Price EUR Indeed the theta junction to case depends on the header material, high power devices can use copper lmm317 PRR mentioned, but in my experience that is not common for mass market normal power products. September 16, Introduction In collaboration with Intertek, Distrelec is offering a calibration service for new electronic test and measurement llm317. Maybe the steel version is Mil rated or something. I suspect most TO-3 business is not for new designs but repair parts, crazy expensive military, etc.

Our expert team have over 25 years experience solving problems and providing expert advice.

To-3 are becoming more of an obsolete package. Al is not up as much. If the detected ,m317 is too large in relation to factory specification, adjustment of your data logger or measuring instrument will be required.


Products The range of this service include, but not limited to: The product Linear voltage regulator 1. Reduce paperwork and access all invoices in one place using My Account.

What do I receive if I choose a calibrated product at Distrelec? Low volume pricing anomalies happen Our website uses cookies, from us and third parties, to personalise your experience and show you products and adverts that may be of interest to you.

The T3o calibration certificates include:. C2 is a uF 50 volt electrolytic that will charge up to almost 40 volts with a It is exceptionally easy to use and requires only two external resistors to set the output voltage.

Dynamic pricing factoring in supply,demand, and reorder points may cause such distortions. Send to a friend. Please visit our website to find instruments which can be calibrated.

Adjustable LM Volt Power Supply

Looks like the mystery is solved. So maybe what’s happening is they are different parts, I mean, maybe aluminium is a fake part or something like that. Please provide as much detail as possible regarding itemLinear voltage regulator 1. D1 could also be four 3 amp diodes. Both vendors have a lot of in stock for both types.

Must be 20 cents of copper in there. L1 is a to 24 volt transformer. Items which are on stock will be shipped out for calibration within 24 hours. Furthermore, both line and load regulation are better than standard fixed regulators. Usually the time for the calibration of your device can be handled within 5 working days.


This LMT voltage regulator chip aka LM works in exactly the same way as the LMT voltage regulator, the only difference being it can deal with higher currents. After calibration is performed, you will receive an ISO certificate from Intertek, which is valid for 12 months.

I spent most of my career effort in this area focussed more on resistance between case and sink and sink to ambient.

Register now Forgot password. We will check the case and contact you as soon as possible. This additional time for the calibration should be taken into consideration to your normal delivery time. Can I return the calibrated item if I am not satisfied with the device itself?

OK, I understand – continue. You need to register to use this feature. An identification of the calibration method eg. How to get the instrument calibrated? Save this product to the following list s. Maybe the datasheet yo3 give some clues at to standards the two versions meet.

Linear voltage regulator 1.
