Why is it important to keep lead lengths short for components used in circuits for VHF and above?
To increase the thermal time constant
To minimize inductive reactance✓Correct answer
To maintain component lifetime
All these choices are correct
Explanation
Every length of wire has inductance of roughly a nanohenry per millimetre, and the reactance of that inductance grows with frequency. At VHF and above even short leads present enough inductive reactance to detune circuits and degrade bypassing, so leads are kept as short as possible.
