Note1: Values have been obtained by applying the test system shown in Fig. 1 and maximum 5,5 V power supply.
Note2: The minimum and maximum showed values are determined by the device’s construction tolerance.
To define the working frequency of the device, add to these values the deviation caused by the thermal variations (see fig. 3).
Note3: To keep the parameters within the limits established by the rules in force, (see para. “Reference Rules”), it is recommended to
supply the circuit with not more than 5,5V and to comply with all the recommendations specified in para “Device usage”.
Messrs AUR°EL declines all responsibilities in case the a.m. recommendations are disregarded.
Technical features are subject to change without notice. AUR°EL S.p.A does not feel responsible for any damage caused by the device’s misuse.

Device usage
In order to obtain the performances described in the technical specifications and to comply with the
operating conditions, which characterize the Certification, the transmitter has to be mounted on a printed
circuit, and keep into consideration what follows:
5V dc supply
1. The transmitter must be supplied by a very low voltage source, safely protected against short circuits.
2. Maximum voltage variations allowed: ± 0,5 V.
3. De-coupling, next to the transmitter, by means of a minimum 100.000 pF ceramic capacitor.
Ground
1. It must surround at the best the welding area of the transmitter. The circuit must be double layer, with
throughout vias to the ground planes, approximately each 15 mm.
2. It must be properly dimensioned, especially in the antenna connection area, in case a radiating whip
antenna is fitted in it (an area of approximately 50 mm radius is suggested).
Technical features are subject to change without notice. AUR°EL S.p.A does not feel responsible for any damage caused by the device’s misuse.
