You’re probably best off retrofitting with a TO however. They’re long gone out of production. I don’t think the mixing console it feeds will draw 1. Quickly Enter the access of compare list to find replaceable electronic parts.

I’ll try this one and see how l,7812k it lasts.

Is the TO-3 version much better than the plastic TO? Please log in to request free sample. You must log in or sign up to reply here. It’s been a year so far and not one time has it shut down from over heating. Yes, my password is: I’d suggest sinking it directly to the chassis with an insulator and lots of thermal paste. Is the metal TO-3 case too expensive to manufacture? NTE is the replacement and cost less.

Remember that heatsink paste only complements the contact – fill the air voids. Of course if you have to deal with insulation, you’re screwed. It’s a Soundcraft CPS power supply, this is the heat-sink, devices are insulated.

LavaneJun 24, Is it due to availability? Is it some very special part? The former will require significant redesign however. I’ll check the mixer specs datashewt see if I need a second device in parallel, but I think with 25W it will be fine.

You may still need to check whether the circuit will support the extra current from the ADJ pin. I’m pushing it hard and although a TO pkg. Torque down properly – don’t overtorque and cause the flange to bend or too little, leaving air voids.

I know its real because its from That explains the price. Discussion in ‘ DIY ‘ started by elnaldoJun 24, The soft silicone insulation at least removes lm7812 of the air voids, but still not better than metal-metal contact. Check the 78xx km7812k application notes for how to use a high power parallel bypass transistor to make a high current regulator.

I can add some smaller heat-sinks inside the cabinet, using one of the TO-3 screws unused with the TO device. 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.

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

The Valley of Chief Black Hawk. I don’t have the plastic covers. I’m running a dual regulator right at its max rating to regulate a pair of B tube filaments. Is my math right?

Specifications Contact Us Ordering Guides. If your close to the max extra heat sinking should work. 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. Main problem of doing so is that the thermal resistance of the TO-3 is better than TO Funny, I have a new old stock that I purchased in for a power supply project datzsheet ended up using a to instead.

It’s likely that not many are made in T cases. One was an NTE and I wanted to replace it but saw the prices you did and thought otherwise. Adding a much bigger heat sink mounted to the chassis top plate really helped. Please review product page below for detailed information, including LMK price, datasheets, in-stock availability, technical difficulties. I’d also be getting the TO and heat sink it as necessary.

Wing Shing Computer Components. Other possibilities include adding a series pass transistor or diode drops so that the LMT doesn’t take the brunt of the drop. WatthourJun 24, You could mount the regulator somewhere else to make it easier to add one if needed as sKiZo suggested. STMicroelectronics’ two new microcontroller product lines enhance the datawheet 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.

Do you already have an account? You can always stretch the leads to fit the board. If you go the TO route, you could indeed hook up two TO’s in parallel with a low value resistor say 0.
