Radiation from ambient and extraneous sources has a great impact on our electrical systems when considering its effect on performance, malfunction, data loss, and system degradation. RFI (radio frequency interference) and EMI (electromagnetic interference) shielding and absorbing materials are crucial in providing protection against such interference.

One of the shielding and absorbing materials, 3M 1170 0.75"SQ-250, offers excellent performance for its cost. The product is made of a metallic copper composite material with a 0.75-inch square shape. It is the perfect choice for applications including defense electronics, air traffic control, and satellite communication. Further, its semi-conductive elastomeric adhesive provides a durable layer of protection against EMI and RFI emission.

The working principle of 3M 1170 0.75"SQ-250 is quite simple. It works by creating electrical or Faraday cages over the electronic devices. These cages are designed to absorb and block any external EMI and RFI radiation from entering the system by blocking out any high-frequency energy that may be present. The material\'s semi-conductive elastomeric adhesive helps ensure that the material is firmly attached to the circuit board or electronic device and does not move or separate when subjected to shock or vibration.

In addition to providing protection against EMI and RFI radiation, 3M 1170 0.75"SQ-250 also acts as an absorber of RF energy. This energy is absorbed and dissipated into the environment, effectively reducing the radiation levels entering the system. This prevents disruption of the system\'s normal operation and reduces the possibility of electromagnetic radiation exposure to personnel.

3M 1170 0.75"SQ-250 is the perfect choice for applications requiring EMI and RFI shielding and absorbing materials. Its semi-conductive elastomeric adhesive ensures a long-lasting and reliable layer of protection against any incoming interference, and its RF absorption properties provide additional protection against external radiation. The product is ideal for aerospace, defense electronics, air traffic control, and satellite communications applications.
