One was an NTE and I wanted to replace it but saw the prices you did and thought otherwise. 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.

Torque down properly – don’t overtorque and cause the flange to bend or too little, leaving air voids.

Why this Voltage regulator is so expensive ??

LMK – ExcessChip Technology

I don’t think the mixing console it feeds will draw 1. I redid a Soundcraft Delta power supply that had like 5 of those TO-3 guys in it. If it blows this next month Dagasheet modify the circuit to install To devicesperhaps with a resistor in parallel. Adding a much bigger heat sink mounted to the chassis top plate really helped. Is the TO-3 version much better than the plastic TO?

Check the 78xx regulator application notes for how to use a high power parallel bypass transistor om7812k make a high current regulator. I’ll try this one and see how long it lasts.

You may still need to check whether the circuit will support the extra current from the ADJ pin. Log in or Sign up. You can always stretch the leads to fit the board. 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.

Do you already have an account? LavaneJun 24, Please log in to request free sample. The soft silicone insulation at least removes some of the air voids, but still not better than metal-metal contact. Discussion in ‘ DIY datssheet started by elnaldoJun 24, That’s what I did it worked fine. Wing Shing Computer Components. I’m running a dual regulator right at its max rating to regulate a pair of B tube filaments.

Is the metal TO-3 case too expensive to manufacture? Mouser link No Affiliation https: If you go the TO route, you could indeed hook up two TO’s in parallel with a low value resistor say 0. You could mount the regulator somewhere else to make it easier to datasbeet one if needed as sKiZo suggested.

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. Pict from the internet, not mine: The Valley of Chief Black Hawk.

Want to gain comprehensive data for LMK to optimize the supply chain include cross references, lifecycle, parametric, counterfeit risk, obsolescence management forecastsplease contact to our Tech-supports team. You may be better off drilling new holes for the TOs, using the existing TO-3 holes may not work well. NTE is the replacement and cost datashest.

National Semiconductor

The former will require significant redesign however. They’re long gone out of production. Is it some very special part? I’d suggest sinking it directly to the chassis with an insulator and lots of thermal paste.

It’s been a year so far and not one time has it shut down from over heating. I don’t have the plastic covers. I’m guessing demand must be near zero. It’s likely that not many are made in T cases. ConradHJun 24, Lavane and Pio like this. I can datahseet some smaller heat-sinks inside the cabinet, using one of the TO-3 screws unused with the TO device.
