Thick Film Resistors
« on: June 19, 2022, 11:28:11 AM »
Hello,

I'm building a 20 years old project that use this kind of resistors.

TA205PA82R0J

I think that the author select this resistors because the space is very tight, and use to-220 style resistors.

The problem is I can't found this resistors anymore. Anybody know a replacement or a trick suggestion?

Thanks.

TA205PA82R0J datasheet call for 82Ω 5W..!!

I'm not sure if there is enough space for equivalent ceramic resistors..

or even for metal-oxide equivalent..

TA205PA82R0JE is almost identical, and still available.

What's the project?  If we knew maybe there's better options.

I worked on a high-frequency project which used these because of the low inductance.

They can be bent back and forth an eventually break off.

The project is a tube headphone amp. I think that I try to use metal oxide resistors. This Thick Film are very expensive!!
