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

Build an Adjustable volt power supply with the LM by Lewis Loflin The LM is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1. 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. Reduce paperwork and access all invoices in one place using My Account.

To-3 are becoming more of an obsolete package. Circuit Operation L1 is a to 24 volt transformer. Usually the time for the calibration of your device can be handled within 5 working days. Country of origin United States US.

If you have a lot of dissipation, you need the steel package. Can I return the calibrated item if I am not satisfied with the device itself?

If I don’t know how it works, I prefer don’t turn it on. If the detected deviation is too large in relation to factory specification, adjustment of your data logger or measuring instrument will be required.


You need to register to use this feature. Aluminum has higher thermal conductivity than steel, so I’d bet it’s a Mil spec for ruggedness. 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.

Dualflip on September 16, Share this product by email Print this page Report an error Report an error Thank you for helping us with our website! Only available while stocks last. More about lead time. An error occurred the product could not be saved. The measured values detected by the calibration Calibration in a controlled environment measuring laboratory. It is exceptionally easy to use and requires only two external resistors to set the output voltage.

JR PS; Sometimes pricing distortions are just because part is low sales volume. Steel is cheaper so the old school mass production part Register now Forgot password.

Maybe the datasheet will give some clues at to standards the two versions meet. Can I get my instruments re-calibrated and is it necessary? Linear voltage regulator 1. The price for the calibration service is already included in the final price for calibrated version. Introduction In collaboration with Intertek, Distrelec is offering a calibration service for new electronic test and measurement instruments. Expert technical support on hand Our expert team have tp3 25 years experience solving problems and providing expert advice.


The reading and accuracy of the instruments may change over time. By using a heat-sinked pass transistor such as a 2N Q1 we lm3317 produce several amps of current far above lm137 1. OK, I understand – continue. Al is not up as much.

5pcs LM317K LM317 TO3 Transistor dc-dc

An identification of the calibration method eg. Thank lm31 for your message. Please enter your name and your e-mail address.

D1 could also be four 3 amp diodes. What’s the part number of the steel version? Above we boost the current out of a LM What application would require a steel case that aluminum wouldn’t work? Maybe the steel version is Mil rated or something.

Article information Previous Article Number: 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. The measurement error is documented on a calibration certificate, which serves as proof.

Our expert team have over 25 years experience solving problems and providing expert advice. IIRC the lateral power mosfets from Hitachi were only made using aluminum cases. Technology Remaking the World. Price of copper is UP. L1 is a to 24 volt transformer. In collaboration with Intertek, Distrelec is offering a calibration service for new electronic test and measurement instruments.
