Why are DIP through-hole package ICs not typically used at UHF and higher frequencies?
Pick an answer to check it.
Answer: C. Excessive lead length
The long leads of DIP packages add inductance and capacitance that cause problems at UHF and above. Excessive lead length is the issue, not the epoxy.
Tip: Long leads hurt at UHF.
