7M3-272 Description

Short technical summary and product information.

The Coilcraft 7M3-272 is part of the "Slot Seven" series of 7 mm tunable inductors. These inductors are designed for versatility and operate over a wide frequency range, with adjustable inductance values achieved through slotted ferrite tuning cores. The 7M3 series provides higher inductances and additional magnetic shielding compared to other variants.

Key electrical specifications include a nominal inductance range of 2.4 µH to 3.0 µH at 25 MHz, with a minimum Q factor of 27 at 25 MHz. The maximum DC resistance (DCR) is 0.898 Ohms at 25 MHz. The component is housed in a 7 mm package and features a metal can for electrostatic shielding. Terminations are pins made of tin-lead over tin over copper over iron.

This product is not RoHS-compliant due to lead content in the core. It is suitable for wave soldering with a recommended maximum board surface temperature of 168°C for no more than three seconds. Pre-heating is advised to minimize time over the solder nozzle. The Coilcraft Designer's Kit M106 is available for evaluating multiple coils.
