如表二所示PTC测试项目中,UL认证及CSA认证的不同处,在于CSA认证需要额外针对样品做三百小时的高阻值状态下的寿命测试。在耐久测试方面,CSA认证称之为TripEnduranceTest,其测试条件与UL认证不同的地方是,UL认证要求需完成一定的循环次数,而CSA认证则要求先在额定电压下测试4小时,然后再调高电压至120%并测试4小时,最后...

The controversy over opening up FM Radio to new entrants remain unresolved when the National Telecommunications Commission (NTC ) failed to supervise a test broadcast by upstart broadcasting firm Media One Broadcasting Co., Inc. (Media One) ordered by the House of Representatives last week.Manila ...
NTC stands for "Negative Temperature Coefficient". NTC thermistors are resistors with a negative temperature coefficient, which means that the resistance decreases with increasing temperature. They are primarily used as resistive temperature sensors and current-limiting devices. The temperature sensitivity coe...
The approach is validated by silicon measurement on a test chip in a 40nm low-power processing technology. Advanced monitoring, control and run-time error mitigation schemes enable the operation of these memories at the same optimal near-Vt voltage level as the digital logic. Reliability ...
在光伏行业中,光伏组件的参数分为STC和NTC两类。 STC,即标准测试条件(Standard Test Conditions),指组件被测试时所使用的环境参数,如光照强度、空气质量、温度等。标准测试条件要求光照强度为1000W/m²、空气质量为AM1.5以及温度为25℃。 NTC,即额定测试条件(Nominal Test Conditions),指组件在实际使用中所处的环...
