Pict from the internet, not mine: Is the metal TO-3 case too expensive to manufacture? I can add some smaller heat-sinks inside the cabinet, using one of the TO-3 screws unused with the TO device. ConradHJun 24, I’ll try this dataheet and see how long it lasts. I don’t think the mixing console it feeds will draw 1. Maximize air space around it as well.

Is the TO-3 version much better than the plastic TO? NTE is the replacement and cost less. You want metal-metal contact ideally, not through heatsink paste. Careful, bare metal contact is always better than adding anything in between – especially air voids. I think I’m going the TO route I can get it locally. That’s what I did it worked fine.


If your close to the max extra heat sinking should work. datasheeet

Selling LMCT, LMCV, LMK with LMCT, LMCV, LMK Datasheet PDF of these parts.

If you go the TO route, you could indeed hook up two TO’s in parallel with a low value resistor say 0. Lavane and Pio like this.

Is my math right? STMicroelectronics’ two new microcontroller product lines enhance the energy efficiency, functional integration and design flexibility of the STM32F4 basic product line high-end products to meet the technical requirements of high-performance embedded design.

Quickly Enter the access of compare list to find replaceable electronic parts.


I’d suggest sinking it directly to the chassis with an insulator and lots of thermal paste. You may be better off drilling new holes for the TOs, using the existing TO-3 holes may not work well.


That explains the price. Of course if you have to deal with insulation, you’re screwed. Main problem of doing so is that the thermal resistance of the TO-3 is better than TO Lm812k name or email address: I don’t have the plastic covers.

One was an NTE and I wanted to replace it but saw the prices you did and thought otherwise. Bill Ferris and Lavane like this. If it blows this next month I’ll modify the circuit to install To devicesperhaps with a resistor in parallel. Torque down properly – don’t overtorque and cause the flange to bend or too little, leaving air voids.
