The isolator μModule® technology used by the LTM2883 has been independently evaluated, and successfully passed the RF and magnetic field immunity testing requirements per European Standard EN 55024, in accordance with the following test standards: EN 61000-4-3 for radiated, radio-frequency, and electromagnetic field immunity; EN 61000-4-8 for power frequency magnetic field immunity; and lastly, EN 61000-4-9 for pulsed magnetic field immunity. Tests were performed using an unshielded test card designed per the data sheet PCB layout recommendations. Specific limits for each test are shown in the table. The LTM2883’s EMI performance is shown on the right, measured using a Gigahertz Transverse Electromagnetic (GTEM) cell using the method detailed in IEC 61000-4-20, which covers testing and measurement techniques for emission and immunity testing in transverse electromagnetic waveguides. As can be seen, both LTM2883 demo boards, the 3V DC1748A-A in blue and the 5V DC1748A-B in green, are well below the CISPR22 Class B limit in red.
