DC Resistance and Q value for  EQ Inductors
We will make the dc resistance as small as possible but the value will depend on the inductance and frequency.

L(H) R Q
0.1 0.5 125
1.0 57 109
10 600 104

Typical R and Q values at 1000 Hz

Tolerance
We can only guarantee the inductance value as measured by our meter as meters vary considerably.

We have a number of standard EQ inductors for pro-vintage gear see EQ INDUCTORS.
