VTC on soliciting opinions based on trying to get into the brain of the guy who designed it. For example, sometimes processor pins may have internal weak pullups on them during power-on and reset. Those weak pullups could turn on a transistor. The pull-down can make sure it stays off until code has control of the output. Add a comment. Active Oldest Votes.

Some manufacturers are using them in built into electromechanical locks these days. However I would err on the side of caution and allow for it unless confirmed the strike does have it fitted internally. You would have to check the part number of the strike you end up using. This allows you to improve resistance to false or low-level signals. Dwayne Reid Dwayne Reid The Overflow Blog. Does ES6 make JavaScript frameworks obsolete?

This product has shipping restrictions, so it might have limited shipping options or cannot be shipped to the following countries:. Added to your shopping cart. Commonly used in breadboards and other prototyping applications, these 1K ohm resistors make excellent pull-ups, pull-downs and current limiters.
These thick-lead versions of the resistors fit snugly into a breadboard with very little movement, so you should have few to no issues using them in your next project! If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics. Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

Commonly used in breadboards and perf boards, these 1K Ohm resistors make excellent pull-ups, pull-downs, and current limiters. Note: Although these come in bags marked with a quantity of 25, they don't always contain So we'd rather call it 20 and hope that you get extras.
