FAQ
Q: What is the difference between EMI and RFI?
A: EMI (Electromagnetic Interference) is a broad term for unwanted electromagnetic noise that can disrupt electronic devices. RFI (Radio-Frequency Interference) is a specific type of EMI that occurs in the radio frequency spectrum. All RFI is EMI, but not all EMI is RFI. EMC filters are designed to suppress both types of interference.
Q: What is the difference between a common mode choke and a ferrite bead?
A: A common mode choke is typically used on power or signal lines to suppress common-mode noise across a wide frequency range. An EMI ferrite bead is a surface-mount device often used on PCB traces to filter high-frequency noise from a specific line. Both are EMI suppression components but are used in different applications and configurations.
Q: Can SHINHOM provide custom EMC filter components?
A: Yes, we offer comprehensive OEM/ODM services. We can customize parameters such as inductance, impedance, current rating, dimensions, and mounting configuration to meet your specific design needs.
Q: What quality certifications do SHINHOM EMC filters meet?
A: Our EMC filter components are manufactured under ISO 9001:2015 and IATF 16949:2016 (automotive) quality management systems. They are RoHS, CE, and REACH compliant, with UL recognition available for many models.
