Insert Molded Coils
Product ID: 2901-01, 2901-02, 2901-Series
- Plastic molded.
- High reliability.
- Low cost.
- Test equipment: Q meter (HP 4342A)
- Measurement:
- Q and L measured with 1/2" long of TCW#16 soldered along the coil leads and with one end flush with the bottom of the coil then bent 1/4" down from stand off at an angle of 90 degree, except type 2901 with leads connected directly.
- L min. measured with core halfway out top of form, except type 2101, 2303, 2308 without core.
- Inductance greater then 0.1uh read at recommended Q meter frequency.
- Inductance below 0.1uh calculated from readings taken at 50MHz.
