The soft silicone insulation at least removes some of the air voids, but still not better than metal-metal contact. Do you already have an account? I redid a Soundcraft Datashret power supply that had like 5 of those TO-3 guys in it. You may still need to check whether the circuit will support the extra current from the ADJ pin.

Pict from the internet, not mine: You’re probably best off retrofitting with a TO however. Register Log in Shopping cart 0 You have no items in your shopping cart. Adding a much bigger heat sink mounted datashret the chassis top plate really helped. The new type of capacitor has a space-saving design with two, three or even ten identical capacitors connected in parallel on the same terminal to increase the capacitance.

Is the TO-3 version much better than the plastic TO? Quickly Enter the access of compare list to find replaceable electronic parts. Want to gain comprehensive data for LMK to optimize the supply chain include cross references, lifecycle, parametric, counterfeit risk, lm7812, management forecastsplease contact to our Tech-supports team.


I can add some smaller heat-sinks inside the cabinet, using one of the TO-3 screws unused with the TO device. No, create an account now. Torque down properly – don’t overtorque and cause the flange to bend or too little, leaving air voids.

You must log in or sign up to reply here. Careful, bare metal contact is always better than adding anything in between – especially air voids. If it blows this next month I’ll modify the circuit to install To devicesperhaps with a resistor in parallel.

The Valley of Chief Black Hawk.

You may be better off drilling new holes ddatasheet the TOs, using the existing TO-3 holes may not work well. Remember that heatsink paste only complements the contact – fill the air voids. LavaneJun 24, Bill Ferris and Lavane like this. Yes, my password is: One was an NTE and I wanted to replace it but saw the prices you did and thought otherwise.

If your close to the max extra heat sinking should work. Is it some very special eatasheet Main problem of doing so is that the thermal resistance of the TO-3 is better than TO I’ll try this one and see how long it lasts. That explains the price.

I think I’m going the TO route I can get it locally. I don’t lm7821k the mixing console it feeds will draw 1. Share This Page Tweet. It’s been a year so far and not one time has it shut down from over heating.

I’ll check the mixer specs to see if I need a second device in parallel, but I think with 25W it will be fine.

Of course if you have to deal with insulation, you’re screwed. Specifications Contact Us Ordering Guides. Mouser link No Affiliation https: That’s what I did it worked fine. They’re long gone out of production.

I’m pushing it hard and although a TO pkg. It’s a Soundcraft CPS power supply, this is the heat-sink, devices are insulated. Check the 78xx datashset application notes for how to use a high power parallel bypass transistor to make a high current regulator. ConradHJun 24, You could mount the regulator somewhere else to make it easier to add one if needed as sKiZo suggested. I’m running a dual regulator right at its max rating to regulate a pair of B tube filaments.

Funny, I have a new old lm7812m that I purchased in for a power supply project and ended up using a to instead.
