Resistors/caps with high temperature tolerance

AI Thread Summary
For high-temperature tolerant resistors and capacitors, options are available that can withstand temperatures up to 155°C for resistors and 125°C for ceramic capacitors. It's important to consider the power levels when selecting resistors. Ceramic capacitors, particularly X7R types, maintain stable performance up to 125°C, but users should check the temperature coefficient graphs for compatibility with their circuits. Resources like the Digikey catalog can provide specific examples and options for these components. Selecting the right type ensures reliability in high-temperature applications.

Hi guys,

need to purchase some resisters and caps that can tolerate temperatures upto 125 deg. cel.

any ideas where i can find some - or what type i should be looking for??

thanks!

Resistors are routinely rated up to 155C. What power levels are you talking about?

Caps are a different matter, depending on the value and type. Ceramic caps are rated up to 125C -- you just have to look at the tempco graph for each ceramic type in order to see if the variation will be tolerated by your circuit. If you can use X7R ceramic caps, they are pretty flat up to 125C.

Just look in your Digikey catalog for some examples.
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
