Frequency for leaded RLCs - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Hi People. I've always done electronics maintenance, not design. But I'm wanting to do some experimentation on some remote control low power circuits (train layout for switching and lights). I don't want to have to fool with the surface mount components because they're too hard to work with without special equipment. What is a good rule of thumb for the highest frequency I can use without having to worry to much about lead inductance for resistors, inductors, and capacitors. Any other gotchas for leaded circuits?

Thanks for any help.

Hello Tbone,

Up to a frequency of 1MHz you should not expect any big problems.

However, if you plan to use any switched mode power supplies (Buck or Boost converters), I would recommend to use SMD components because the layout has a crucial effect on the performance of these circuits.

I hope this helps.
