Frequently asked questions
What does the VFK4R suffix specify on the MKL03Z16?
VFK4R encodes the 24-QFN (4x4 mm) exposed pad package with extended temperature grade and tape-and-reel packaging. V = QFN package, F = 24 pins with exposed pad, K = -40 to 105°C temperature grade, 4R = tape-and-reel orientation. Confirm this is the exact footprint variant your layout targets.
