  • Resistance temperature detector (RTD) formed with a surface-mount-device (SMD) structure
    Patent number: 5896081
    Abstract: The present invention discloses a surface-mount resistance-temperature-detector (RTD) supported on a substrate. The surface-mount RTD includes a resistive strip disposed on a top surface of the substrate having a substantially linear temperature resistance coefficient (TCR) over a predetermined temperature range for measurement. The surface-mount RTD further includes two top terminals disposed on two opposite end on the top surface of the substrate wherein each of the top terminal connected to one end of the resistive strip. The surface-mount RTD further includes two bottom terminals disposed on a bottom surface of the substrate wherein each of the bottom terminals is disposed below one of the top terminals. The surface-mount RTD further includes two edge conductive plates each disposed on an edge surface of the substrate connected to one of the top terminals to a corresponding bottom terminal below.
