For applications requiring frequent reconnection, a threaded or push-pull connector would be a better fit. ## SMT Termination and Board Layout Surface-mount termination with solder shield termination and solder contact termination — the centre pin and outer shield both reflow onto the PCB pads. The LCP (Liquid Crystal Polymer) dielectric maintains dimensional stability through reflow and holds the 75 Ohm impedance across the operating temperature range. The board footprint must match the D.FL75 series recommended land pattern to keep the impedance through the launch; a ground plane cutout under the pad is typical for this connector class.","metaTitle":"Hirose D.FL75-R-SMT-1(40), 75 Ohm SMT Receptacle, 12 GHz","metaDescription":"Hirose D.FL75-R-SMT-1(40) 75 Ohm SMT receptacle, male pin, snap-on, rated to 12 GHz.
