Note: Output filtering capacitor C2 is electrolytic capacitor, it is recommended to apply electrolytic capacitor with high frequency and low resistance. For
capacitance and current of capacitor please refer to manufacture’s datasheet. Capacitance withstand voltage derating should be 80% or above. C1 is
ceramic capacitor, which is used to filter high-frequency noise.
to use S10K300.
TVS is a recommended component to protect post-circuits if converter fails. External input FUSE
model is recommended to use 3.15A/250VAC, slow fusing. External input NTC model is recommended to use 5D-9. External input MOV model is recommended

“tensymetry”这个词在《韦伯斯特词典》中没有解释，但在医学界却广为人知。由Tensys Medical Systems公司开发的tensymetry是一种使用生物机械、电气、软件工程的专有组合技术。利用这三种强大的技术，你可在手术室内对病人的心跳血压进行精确、连续、实时和非侵入性测量。 该技术结出的果实就是该公司的T-line Tensymeter产品。该产品线的最新进展是去年...[详细]
中风发生时，一切都是以秒来计算的。延误治疗可能导致大脑重大损伤。伦敦大学医学院的一位博士Alistair McEwan已经获得行为医学研究所(Action Medical Research)的同意，为急救人员开发一种无线诊断系统来减少时间延误。感谢抗血栓药物，一些病人在病情发作的三个小时之内可以完全恢复。但出血也会导致中风。医生在治疗之前需要确定发病原因，因为不适当的服用抗血栓药物会加重损害。...[详细]
