Yeah, but they will just insert their planned obsolescence somewhere else. Merry Christmas and Happy New Year!

Maybe Robert, it is easier to invent new circuits that do not need e-caps anymore (LOL)? Have a great Xmas and a good New Year! (same wishes go to Jestine and all Readers/fellow contributors!)

That is true. Well if we invent a cheap nontoxic dependable replacement for e-caps we will be very rich men!

HF coils do not make them more expensive than the often more expensive standard 50/60Hz transformer types in power supplies. The e-cap problem always causes much polution because in time they always will fail and even will destroy our expensive instruments like our Tektronix scopes. It should not mean that because better technical solutions do not yet exist the e-cap technology is perfect as it is. And if in future all cars use lithium-ion batteries as power source it probably will cause new environmental problems too. I mean polution has its price too.

That is educative and it explains why we should put more emphasis on visual inspection first.

Oh! My! Those leaky capacitors make a sticky job! Cleaning the board and handling it is a difficult job! Well done!

Hi Albert,

Would you rather have the "weak link" to be a more expensive component? Luckily for us that most e-caps are not very expensive. Without e-caps we would have an even more throw-away society than we already have.

If they would make power supplies that store energy in a magnetic way instead of in the capacitive way that would eliminate these bulge and leakage problems completely. Coils hardly ever deteriorate. But hélas it doesn't exist yet.
