SRF0905-472Y

Common mode chokes (CMCs) are essential components in modern electronic equipment, providing a means of suppressing interference from high frequency or common mode noise. SRF0905-472Y is a type of CMC specifically designed to meet stringent requirements for the suppression of higher frequency interference in a wide range of applications. The robust design and superior performance of the CMC make it suitable for use in power supplies, consumer electronics, automotive, industrial, medical, and military applications.

The SRF0905-472Y is a termoformed CMC with a 47Ω termination resistance and three 6mm x 5mm shielded cores. It has a self-resonant frequency of 905 MHz and is rated for use at temperatures ranging from −25°C to 125°C. The shielded cores allow for the rejection of common mode interference while the terminations provide a mechanical barrier against arcing and corona discharge. The CMC is available in multiple international environmental approvals.

The SRF0905-472Y is designed to provide superior suppression of high frequency noise generated by electrical equipment. The CMC is constructed with a high temperature plastic case and has three concentric cores of different sizes. The innermost core is made from a ferrite core with a laminated structure. This core is designed to provide a greater level of EMI (electromagnetic interference) suppression, as it absorbs energy passing through the CMC. The larger outer core is made from an electromagnetic suppression material with a higher inductance value. This core serves to reject higher frequency noise that may pass through the inner core.

In order to ensure optimal performance, the SRF0905-472Y must be installed correctly and securely. The CMC should be properly spaced from other components on the substrate, as this helps to ensure better performance and reduce the chance of arcing or flux leakage. Additionally, the CMC should be securely connected to the component ground plane. Ground planes are made of conductive material which provides additional shielding from outside interference.

The SRF0905-472Y is a highly effective CMC, providing excellent performance for a wide variety of applications. The CMC is capable of rejecting a wide range of high frequency or common mode interference, as well as providing superior protection against arcing and corona discharge. It is available in multiple international environmental approvals, ensuring that it can be used in virtually any type of environment. The robust design and superior performance of the SRF0905-472Y make it an ideal choice for a wide range of applications.
