| Features and Applications The JSTC04 is a high-frequency multi-junction thermal converter device for high-precision AC-DC transfer standards. Using NIKKOHM’s unique thin-film thermopile technology, this device realizes sensitivity of 10-6 to 10-7 for comparing rms power between ac and dc input voltages. The JSTC04 thermal converter is designed to minimize effects from stray inductances and capacitances in the input circuit. The frequency characteristic of the AC-DC transfer difference is self-calculable, and has been evaluated to be better than 0.001% in the frequency range between 10kHz to 100 kHz, and better than 0.01% up to 1 MHz. All the JSTC04 devices are identified by serial production numbers, and are individually inspected and guaranteed for the specifications. The inspection data include input resistance, output resistance, sensitivity (output voltage), and reversal error. The JSTC04 thermal converter has been developed through the collaboration with AIST (National Institute of Advanced Industrial Science and Technology, Japan). 7.0 10.5 15.0 1.5 0.05 3.5 10.5 15.0 |
