25-CBSA-2.0X2.0X0.225 RF Shields

RF shields are physical barriers which are used to reduce the effects of radio frequency (RF) interference between two electronic devices. RF shields are commonly used to protect sensitive electronic equipment from the harmful effects of RF radiation, electromagnetic interference (EMI) and electrostatic discharge (ESD). RF shields can also be used to reduce the number of signals entering and reflected from a device, and to provide added protection from dangerous electrical currents.

The 25-CBSA-2.0X2.0X0.225 RF shield is a component used to reduce the susceptibility of EMI, ESD, and RF radiation on circuits. It is designed to provide isolation for low, medium, and high frequency signals. It can be installed on a variety of printed circuit boards, including, but not limited to, differential pairs, antennas, and radios. The shield is engineered to provide a low loss and attenuation path between the conductors, allowing it to effectively reduce EMI and/or RF interference.

Application Field

The 25-CBSA-2.0X2.0X0.225 RF shield is designed to reduce the risk of interference to audio and video signals, as well as that of EMI and ESD on ICs in high-end smartphones, tablets, and laptop computers. It is suitable for cellular phones, Bluetooth headsets, radios, and other portable communication devices. It can also be used in a variety of other applications, including, but not limited to, medical instruments, LCDs, and television sets.

Working Principle

RF shields provide attenuation of EMI and RF radiation. This protection is achieved by absorbing, reflecting, and/or dissipating energy. Unlike other shielding techniques, RF shielding does not rely on electrical conductors, but instead uses specially designed material to absorb, reflect, and/or dissipate RF radiation. This material generally consists of a conductive layer which is separated by a dielectric layer. The dielectric layer absorbs and reflects the RF radiation and the conductive layer dissipates the RF energy.

The 25-CBSA-2.0X2.0X0.225 RF shield absorbs RF radiation using a conductive layer consisting of a mix of copper, nickel, and gold. The dielectric layer is made of polyimide, a type of plastic-like material which is highly resistant to temperature, pressure, and electrical current. The combination of these two layers creates a high-efficiency shield which can attenuate high and low frequency signals.

The 25-CBSA-2.0X2.0X0.225 RF shield is designed to reduce EMI, ESD, and RF radiation from devices. It is best suited for audio, video, and communication applications in which EMI and ESD protection is of paramount importance. It is a cost-effective solution that can provide an excellent balance between shielding performance and cost.
