High-Accuracy and High-Reliability

Panasonic’s new ERA-1AEB Series Thin-Film Chip Resistors feature a 0201 inch case size and have a 0.05W power rating. Featuring high-reliability and stability at high temperatures and high humidity, the ERA-1AEB Series is usable in demanding automotive applications. These Resistors boast a high accuracy of 25ppm, 0.1%.

Very good specs if you can tolerate staying well within the 50mW rating.

Promising except for the very low 50 milliwatt rating. And surface mount. I hate surface mount because I can't work with them.

I'm not even sure that I can SEE a 0201 size smt resistor.

Too small and too low power for my need. 😱 The smallest I could solder is 0603.

Low maximum voltage rating too.
No markings either, so hard to debug.
Generally resistors improve as you go up in power rating, with lower voltage and thermal distortion

These are super tiny, intended for highly integrated and miniturized circuits like cellphones, tablets and laptops, as evidenced by the 0201 size (this is insanely tiny). This is also why there is such a low max voltage limit and low wattage. These are used in devices optimized to sip power.

I'll assume that in an audio context you want a resistor with low extra noise, low dR/dV, and low tempco for self heating...

It's much easier to get that in a larger package, more thermal mass means less self heating ; lower electric field (V/m) means less dR/dV, and more resistive material means lower noise (all other things being equal)...

Plus, soldering 0201s is a bitch !!!!! it's for robots not humans.
