無線藍牙最佳之選為SMD晶振ECS-240-18-33-JEN-TR3，The ECX-32 series of compact, surface mount crystals is available in an industry standard package ideal for IoT, Wi-Fi and Bluetooth. 
ECS’ ECX-32 series of compact 3.2 mm x 2.5 mm 4-pad MHz quartz crystals offer a wide frequency range of 8 MHz to 54 MHz. The crystals are available with tight stability and tolerance options of ±10 ppm and an extended -50ºC to +125ºC temperature range options. The standard part provides a 20 pF load capacitance but additional load capacitance options of 8 pF, 10 pF, 12 pF and 18 pF. These crystals are ideal for wireless, mobile, IoT, Wi-Fi and Bluetooth applications where board space is critical.

ECX-32系列緊湊的表面貼裝晶體是物聯網，Wi-Fi和藍牙的理想行業標準封裝。

ECS的ECX-32系列緊湊的3.2毫米x 2.5毫米4墊MHz石英晶體提供8 MHz至54 MHz的寬頻率范圍。該晶體具有緊密的穩定性和±10 ppm的公差選項，以及擴展的-50ºC至+125ºC的溫度范圍選項。標準部分提供了20 pF負載電容，但額外的負載電容選項為8 pF, 10 pF, 12 pF和18 pF，這些晶體是無線，移動，物聯網，Wi-Fi和藍牙應用的理想選擇，這些應用的電路板空間是至關重要的。
