The Coilcraft 7M3-681 is a tunable RF inductor belonging to the "Slot Seven" series, housed in a compact 7mm package. This inductor is designed for variable inductance applications, operating over a wide range of frequencies.
Key electrical specifications include a minimum Q factor of 40 at 25 MHz and a maximum DCR of 0.333 Ohms at the same frequency. For lower frequency applications, at 7.9 MHz, the minimum Q factor is 27 and the maximum DCR is 1.49 Ohms. The inductance range for this specific part is 0.612-0.748 µH at 25 MHz, with a nominal value of 0.680 µH.
This inductor is suitable for applications requiring RF filtering, EMI/RFI suppression, power supply ripple reduction, and signal conditioning. Its precision-molded slotted bobbin ensures tight tolerances and high stability. The tuning is achieved via slotted ferrite tuning cores for easy adjustment.
The physical dimensions include a package height of 4.50 mm, a package width of 7.62 mm, and a package length of 7.24 mm. The tab thickness is approximately 0.30 mm. The 7M3 series has a weight ranging from 1.30 to 1.34 grams.
