TDK’s TFM160808ALC Low Loss Thin-Film Metal Inductors | Power Smd Inductor

You really want to look at the DC line, but the 10s line is probably good enough for me. And that crosses the 3V DS at around 450 mA. Really not too shabby for the small package size, but not something you want moving 1A for a long while.

Been there. Use mosfets from motherboard cpu power supply! I’v happened to have new-ish motherboard with unidentifiable mosfets, so i’ve tried them with lipo and bigger motor and it worked and warmed up only slightly, so I’ve had plenty mosfets for my project with smaller motor.

Here is a plot from both my numerical model and the voltage as measured in the actual circuit (I used a Vernier differential voltage probe to get voltage as a function of time).

Here is my personal hierarchy of design considerations for selecting resistors in circuits (apart from form factor): 1. nominal resistance and tolerance, 2. power rating, and 3. temperature coefficient (TC). 4. If there are other considerations beyond 1.-3. then choosing the resistor is a design project on its own.

Como NeoTeo nunca descansa, te invitamos a ti a tratar de hacer funcionar algún elemento que esté preparado para ser alimentado por otras fuentes de energías, con tan sólo tres baterías doble A. Ya que el MC34063A comienza a ser eficazmente operativo a partir de los 4V, creemos que con baterías frescas y una tensión de entrada de 4,5Volts podemos lograr interesantes salidas de tensión y aplicarlas a diversos circuitos y/o equipos.

This is much the same a metal film resistors except that the metal is often tin oxide contaminated with antimony oxide for resistance. This gives it a better performance than either carbon film or metal film in terms of voltage rating, overloads, surges and high temperatures. While carbon film resistors are rated for roughly 200C and metal film, 250-300C, metal oxide works with 450C. However, they have inferior stability properties.

“That started a friendship with Bob, who told this amazing story that starts in China in the 1930s. There was this gifted engineer, K.T. Wang, who was way too smart to work on just his power plant management job. He made up electrical engineering brain teasers for himself and then solved them. Over years of doing this to keep his mind from turning into oatmeal, he noticed there was a pattern to some of these problems. They would be easy to set up, then horribly horrible to solve, and in the end the beast would collapse to something much simpler and very elegant. He wondered, ‘Is there a way to get to the end without going through the middle.’ So, he came up with these weird ad-hoc rules that enabled him to shortcut a lot of the ugly math.

IRLZ44N is pretty common to find around here and is cheap. I also have some IRLB8743 I bought from China that are good for higher currents.

Using the SHA256 encrypted communication protocol developed by the National Security Agency (NSA), all electronic commands and equipment communications are ultra-secure. An easy-to-use app transcends mechanical keys, allowing managers to create virtual keychains of admission that can be modified in real time. Using the app’s dedicated dashboard, locks can be opened and closed, access permissions granted and much more, all from the manager’s remote location and wherever they have access to their phone or computer. Through IoT connectivity, it’s also possible to manage an “ecosystem” of interlocking security systems including those in locks, doors, entrance gates, machines, cabinets and much more. The system gives managers total control over who can use virtual keys, and exactly what they have permission to access and when. The system’s tool tagging feature is particularly relevant to work truck applications and anywhere tools and equipment are regularly transported in and deployed from a vehicle. Not only can managers confirm that the right tools are on board before the truck is dispatched, they can also make sure the same tools are accounted for and loaded before the vehicle leaves the work site.
