0402 Wire Wound Chip Inductor

The original poster probably got the wrong unit. There are 4.7nH ones, but not 4.7uH ones. The 0402 package simply cannot wrap around so many wires. Note that the inductance of the two differs by 1000 times. Moreover, the current "high frequency" is usually in the hundreds of MHz level or even higher, and uH-level inductors are basically not used in signal paths. Even if they are used, considering the control of distributed parameters, the size of the inductor will be very large.

The moderator is right. After all, the Al value is very small for such a small size. 0402 4.7nH should only be available in SMD form. The self-resonance is 4GHz, which should be considered high frequency. However, I see that many of these specifications have been discontinued.
