EMIF02-USB04F3 is a highly integrated audio filter device designed to suppress EMI/RFI noise in all systems subjected to electromagnetic interference. This filter includes ESD protection circuitry, which prevents damage to the protected device when subjected to ESD surges up to 15 kV.
The EMIF02-USB04F3 is a highly integrated audio filter device designed to suppress electromagnetic interference (EMI) and radio frequency interference (RFI). It features built-in electrostatic discharge (ESD) protection circuitry capable of withstanding surges up to ±15 kV on external pins, protecting sensitive equipment such as mobile phones, computers, and MCU boards.
| ESD protection (external pins, air discharge) | ±15 kV |
|---|---|
| ESD protection (internal pins, air discharge) | ±2 kV |
| Operating temperature range | -40 to +85 °C |
| Storage temperature range | -55 to 150 °C |
| Line resistance (R1, R2) | 33 Ω ± 5% |
| Series resistance (R4, R5) | 18.5 kΩ ± 20% |
It is intended for mobile phones, communication systems, computers, printers, and MCU boards where EMI filtering in ESD sensitive equipment is required.
The external pins support an ESD discharge of ±15 kV for air discharge and ±8 kV for contact discharge.
The device operates within a temperature range of -40 to +85 °C.
The maximum line capacitance is 20 pF.
