I was searching for some small size, low value, low current inductors on Mouser, when I noticed that they give a spec for "self resonant frequency" of each inductor. It surprised me to see that parts with very similar current and inductance ratings can vary widely in their self resonant frequency. For example, as low as 1kHz and as high as >1MHz, for two different products rated at ~100mH/50 to 100mA. My instinct would be to choose an inductor whose self resonant frequency is well above the audio range, e.g., 1kHz would seem to be unacceptable for audio. Is this spec indeed something to think about, or does it not matter much? Thanks.
