HC103M2

      The HC103M2 is designed as fast high end humidity sensors for radiosondes / registering balloons.It is designed for SMD automatic assembling with subsequent reflowsoldering.
      Some characteristics of HC103M2 have been concluded into several points as follow.The average increase of capacitance over the working range is 55pF. For the range of 098% RH linear approximation is possible, errors will be lower than < ± 2% RH.The sensor characteristic is determined by the following linear formula: C(RH) = C0 * [1+HC0 * RH] with HC0 = 3420 ± 250 ppm /% RH.For high accuracy requirements, the sensitivity is determined by the following polynomial: C(RH) = C0 * [1 + HC0 * RH + K(RH)].And also its whereby would be K(RH) = A1*RH+A2*RH1.5+A3*RH2+A4*RH2.5 (A1 = 2.6657E-3, A2 = -9.6134E-4, A3 = 1.1272E-4, A4 = -4.3E-6).
      Also some important technical data and electrical specifications about HC103M2.The first one is about its nominal capacitance (at 30°C / 86°F) which would be 160 ± 40 pF.The second one is about its sensitivity which would be 0.55pF /% RH.The third one is about its working range humidity which would be from 0 to 100% RH and its temperature would be from -80 to 120°C (-112...248°F).The fourth one is about its linearity error (0 to 98% RH) which would be less than ± 2% RH.The fifth one is about its hysteresis which would be 1.9 ± 0.25% RH.The sixth one is about its temperature dependence which would be dC = -0.0019*RH*(T-30°C) [pF].The seventh one is about its loss tangent which would be less than 0.05.The eighth one is about its maximum supply voltage which would be 5V max (UPP).The eighth one is about its maximum DC voltage which would be less than 5mV.The ninth one is about its operating frequency which would be from 10 to 100 kHz, recommended 20kHz.The tenth one is about its packaging tray 101.6x101.6 mm (4x4") which would be 240 sensors and its tape and reel would be refer to ordering guide.And so on.For more information about HC103M2, please contact us.
