Please choose appropriate capacitance values to the application frequency. [2] To reduce stlipline influence on RF characteristics, please locate bypass capacitors (C5) close to VDD terminals. [3] For good isolation, the GND terminal (7th pin) must be placed possibly close to ground plane of substrate, and through holes for GND should be placed near by the pin connection. -7- NJG1544HC3 QPACKAGE OUTLINE (USB10-C3) (TOP VIEW) (SIDE VIEW) 1pin INDEX 0.038±0.01 0.14±0.05 0.75 0.8±0.05 2.0±0.05 0.5±0.1 0.5±0.1 0.5±0.1 :Au :FR5 : Epoxy resin :mm :7mg R0.075 0.2±0.1 4 0.3±0.05 10 5 9 8 7 0.2±0.05 6 0.2±0.05 (BOTTOM VIEW) Cautions on using this product This product contains Gallium-Arsenide (GaAs) which is a harmful material. • Do NOT eat or put into mouth. • Do NOT dispose in fire or break up this product. • Do NOT chemically make gas or powder with this product. • To waste this product, please obey the relating law of your country.
