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: Q meter (HP 4342A)
