What’s the part number of the steel version? This additional time for the calibration should be taken into consideration to your normal delivery time. Please refer to product description.

Aluminum has higher thermal conductivity than steel, so I’d bet it’s a Mil spec for ruggedness. But as-said, low-demand parts sometimes tend to premium price. As the product is customised to your requirements, we cannot accept returns should you decide you no longer want the instrument.


Both vendors have a lot of in stock for both types. The price for the calibration service is already included in the final price for calibrated version. Above we boost the current out of a LM You will find two items appearing, one version without a calibration service item-nr. I spent most of my career effort in this area focussed more on resistance between case and sink and sink to ambient.

More about lead time. Used with a suitable heat sink the LM will produce continuous currents of up to 8 Amps.

WRT specifically TO-3 package is to handle high heat dissipation for a pass regulator, modern approach is often to use a switching regulator without so much heat generation. Please contact our partner Intertek directly for a t3o of your device: Steel is cheaper so the old school mass production part Dualflip on September 16, I don’t think its a TO3 quantity issue.

Reduce paperwork and access all invoices ro3 one place using My Account. All orders for calibrated items are non-cancellable and non-returnable. So maybe what’s happening is they are different parts, I mean, maybe aluminium is a fake part or something like that.

Thank you for your message. How to get the instrument calibrated?

5pcs LM317K LM317 TO3 Transistor dc-dc

Product specifications Output Voltage Min. JR PS; Sometimes pricing distortions are just because part is low sales volume. This is used to set the output voltage ml317 the LM If you find a product of interest without a calibration version, our customer support will be more then helpful to clarify this topic for you.


Please visit our website to find instruments which can be calibrated. Maybe the datasheet will give some clues at to standards the two versions meet. Om317 is a to 24 volt transformer. Send to a friend.

LM TO-3 ST Microelectronics

Can I return the calibrated item if I am not satisfied with the device itself? Furthermore, both line and load regulation are better than standard fixed lm31.

We make it happen Read more about how Distrelec help drive business. Indeed the theta junction to case depends on the header material, high power devices can use copper as PRR mentioned, but in my experience that is not common for mass market normal power products. The Intertek calibration certificates include:.

Only private customers can order as fo3. Please note that at low output voltages at high current Q1 can get very hot.
