who cares what the parts are made of? what are their specs? I find myself annoyed by the categories on the distributors sites, I don't care what the resistor technology is, I'll select the parameters I want and what I get I get. |

Is there a universal answer to that? No. I think the engineers desinging Royal Navy torpedoes might care *A LOT*. You sound somewhat impatient - why would that "annoy" you; would you rather they HID such detail? I am sure you're pretty much alone there, if so. |

Test their resistance and capability to withstand 0.25W. If they are within tolerance and dissipate 0.25W fine, they are fit for the purpose. The fact that the leads are thinner should not be a factor, because you didn't buy resistors specified by their lead diameter. |

Resistors are not all equal. --- End quote --- But what specs does the construction affect? I look for a value, tolerance, ppm, wattage and temperature ratings, I expect that to automatically filter the right type of resistor. Same with capacitors although the construction is a bit more in my face there. I don't say "oh I need a polymer", I say "I need low ESR therefore I should look to a polymer", I don't use polymer because I want to use polymer. If I could filter caps of all types and i wanted ultra low ESR naturally the polymers would come at the top of results, if I filtered ot price the standard aluminiums would came on top. |
