Murata Co., Ltd. will commercialize the NFC*2 adjustable capacitor *3 (LXRW19V201-058) with improved withstand voltage*1. Mainly for NFC payment terminal equipment (POS*4 system). This product was mass-produced at the Gangsan Murata Manufacturing Plant in April 2018.
Unlike smartphones and mobile phones equipped with conventional adjustable capacitors, payment terminal devices need to operate under AC voltage. The product achieves an AC rated voltage rating of 30Vpp under applied voltage by improving the internal capacitance configuration (it is a traditional 3) Double).
On the NFC-enabled payment terminal device, in order to support the miniaturization of mobile and the corresponding EMV*5, the fine-tuning of the frequency is more stringent. To meet the same needs, the product is commercialized.
Old-fashioned Bluetooth Speaker
For Old-fashioned Bluetooth Speaker, I personally think that when many people buy Vintage speakers, the appearance is the first priority and the function is second.
We focus on retro Bluetooth speakers,It has high energy density, mini size, light weight and diversified shapes;Excellent fast charging performance, support fast charging and other excellent features with a brand-new design, showing retro nostalgia without losing fashion. It uses a 2.5-inch speaker and has many functions such as FM radio, Bluetooth fast connection, multi-mode switching, and HIFI high fidelity. Wireless Bluetooth 4-10 hours of playback (at 50% volume), which adds to its unique charm.
The sound quality of small speakers is also good. It does not have the same large speakers and power as HIFI speakers, and its sound quality cannot compete with large speakers due to physical limitations. But for the vast majority of users who are not golden ears, the use of small speakers with tablets and mobile phones is sufficient to meet their hearing requirment.
