7M3-391 Description

Short technical summary and product information.

The Coilcraft 7M3-391 is a tunable inductor from the "Slot Seven" series, housed in a 7 mm package. These inductors are designed for versatility across a wide range of frequencies, allowing for easy adjustment via slotted ferrite tuning cores.

 

Key electrical specifications include a nominal inductance of 0.100 µH, with a range of 0.094 µH to 0.106 µH at 25 MHz. The Q factor is a minimum of 27 at 25 MHz, and the maximum DC resistance (DCR) is 0.124 Ohms. The 7M3 series has a typical weight of 1.30 - 1.34 g.

 

These components are suitable for applications requiring precise inductance tuning. The "Slot Seven" series offers tight tolerances and high stability due to its precision-molded slotted bobbins. Custom values can also be provided upon request.
