HC103M2

Mounting Instructions

For shortest response time, in case of mounting onto a printed

circuit board (PCB), HC103M2 shall be positioned over an

opening to allow enough air circulation around the sensor.

For best accuracy it is important to avoid moisture accumulation

such as at the edge of the PCB by selecting appropriate board

material or gold-plating the edge of the opening.

Please refer to the HC103M2 Handling Instructions at

www.epluse.com/hc103m2.

For high accuracy requirements, the characteristic is described by the following polynomial:

C(RH) = C0 * [1 + HC0 * RH + K(RH)]

whereby:

K(RH) = A1*RH+A2*RH1.5+A3*RH2+A4*RH2.5

A1 = 2.6657*10-3

A2 = -9.6134*10-4

A3 = 1.1272*10-4

A4 = -4.3*10-6

Assembling and Soldering

HC103M2 is an SMD (surface mounted device) sensor, appropriate for automatic assembling with

subsequent reflow soldering. Please refer to the Handling Instructions at www.epluse.com/hc103m2.
