C. Features:
1. Plastic molded.
2. High reliability.
3. Low cost.
D. Measurement:
1. Q and L measured with ½” long of TCW#16 soldered along the coil leads and with one end flush with the
bottom of the coil then bent ¼” down from stand off at an angle of 90°.
2. L min. measured with core halfway out of the top of the form.
3. Inductance greater than 0.1uH read at recommended Q meter frequency.
4. Inductance below 0.1uH calculated from readings taken at 50MHz.
E. Test equipment:
