... TECHNICAL INFORMATION FREQUENCY BEHAVIOR The EMIF01-10005W5 is firstly designed as an EMI/RFI filter. This low-pass filter is characterized by the following parameters: - Cut-off frequency - Insertion loss - High frequency rejection Fig A1: EMIF01-10005W5 frequency response curve -10 -20 f(MHz) - 100 Figure A1 gives these parameters, in particular the signal rejection at the GSM frequency is about -24dB at 900MHz, ...

... EMIF01-10005W5 ESD PROTECTION In addition to its filtering function, the EMIF01-10005W5 is particularly optimized to perform ESD protection. ESD protection is based on the use of device which clamps at : This protection function is splitted in 2 stages. As shown in figure A3, the ESD strikes are clamped by the first stage S1 and then its remaining overvoltage is applied to the second stage through the resistor R. Such a configuration makes the output voltage very low at the Vout level ...

... Vout clamping voltage very close to V Fig A5 : Remaining voltage at both stages S1 (Vin) and S2 (Vout) during ESD surge a) Positive surge Please note that the EMIF01-10005W5 is not only acting for positive ESD surges but also for negative ones. For these kind of disturbances it clamps close to ground voltage as shown in Fig ...
