Footprint doesn't match Murata datasheet?

In addition, the datasheet shows "non-resist areas," which points to solder mask openings between some of the pads, likely for RF reasons.

Hello kslamba3,

Hello kslamba3

Thank you for your detailed feedback and for your patience while we reviewed the footprint.

We checked it against Murata’s recommended land pattern and confirmed the following:

GND pad: The I shaped GND copper is correct. The four ground lands are connected by a central electrode, which the datasheet specifies should be covered by solder resist, leaving only the four lands exposed for soldering.

Non resist, non metal area: This was missing from the original footprint. We’ve now defined it on the tStop and tRestrict layers to prevent solder mask coverage and copper pours in this region, as required for RF performance and maintaining the intended 50 Ω impedance matching.

The updated footprint is now available on our site. Please feel free to download it and let us know if the changes meet your expectations.
