V1.2 HC103M2 HC103M2HC103M2 Nominal capacitance C0 (at 30°C / 86°F) 160 ± 40 pF Sensitivity 0.55pF /% RH Working range humidity 0...100% RH Linearity error (0...98% RH) < ± 2% RH Hysteresis 1.9 ± 0.25% RH Response time RH t Temperature dependence dC = -0.0019*RH*(T-30°C) [pF] Loss tangent < 0.05 Maximum supply voltage 5V max (UPP) Maximum DC voltage < 5mV Operating frequency 10...100 kHz, recommended 20kHz Packaging tray 101.6x101.6 mm (4x4”) 240 sensors tape and reel refer to ordering guide 1) more details for t < -20°C on request TTecechnical Dahnical Da tata Fast High End Humidity Sensors for Radiosondes / Registering Balloons CharChar acteristicsacteristics The average increase of capacitance over the working range is 55pF. For the range of 0–98% RH linear approximation is possible, errors will be lower than < ± 2% RH. The sensor characteristic is determined by the following linear formula: C(RH) = C 0 * [1+HC0 * RH] with HC0 = 3420 ± 250 ppm /% RH capacitance [pF] relative humidity [% RH] temperature [°C] response time t63 [sec] For high accuracy requirements, the sensitivity is determined by the following polynomial: C(RH) = C0 * [1 + HC0 * RH + K(RH)] whereby: K(RH) = A 1*RH+A2*RH1.5+A3*RH2+A4*RH2.5 A1 = 2.6657E-3 A2 = -9.6134E-4
Dimensions (mm)Dimensions (mm) Mounting InstrMounting Instr uctionsuctions To allow full access of the air, the humidity sensor should be positioned over an opening in the printed circuit board (PCB). False readings because of humidity assimilation at the front side of the PCB should be avoided as much as possible by using gold-plated-through holes. contact area PCB opening gold plated contact through HC103M2 HC103M2 HC103M2 OrOr dering Guidedering Guide HC103M2 (103M2) TYPE AssembAssemb ling and Solderingling and Soldering HC103M2 sensor series are designed for SMD automatic assembling with subsequent reflow- soldering.
