  • Filtering & Attenuation (.pdf)
    Some caution should be used in evaluating the EMI/RFI filtering capabilities of a surge suppressor. MIL-STD-220B defines the basic testing procedures and test equipment to be used. However, there are certain procedures and measurements that are left up to the user for interpretation. Also, since
  • Application Note on SCADA / Process Automation System (.pdf)
    Many SCADA system installations are in areas where it is exposed to harsh environments of EMI, RFI, multiple/dirty ground, and lightning where in the conventional communication cables have to be protected to run SCADA properly. Apart from this, distances to be covered may involve additional devices
  • HOW TO SELECT THE IDEAL ENCLOSURE GASKET
    electrical and electronic equipment inside the enclosure. While gaskets are primarily used to exclude the external environment from entering an enclosure-such as dust, dirt, water, and Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI)-they can also be used to contain noise or other
  • Design Criteria for Optimum Cooling and Shielding of Enclosures
    of challenges for the packaging engineer. In order to satisfy the demands of a given environment the engineer must consider: mechanical constraints, cooling requirements, EMI/RFI restrictions, shock/vibration, power distribution, cable management, system monitoring, high availability (HA), reliability
  • Littelfuse Varistor Design Examples (.pdf)
    network is there to prevent RFI from being transmitted into the power line (as in a TV set), but also serves to reduce the transient voltage. An analysis shows that the transient will be reduced approximately by half, resulting in about 2.5kV instead of 5kV at the rectifier. This is still to high
  • EMI Shielding With Perforated Metals
    One of the most common uses for perforated metal is to enclose electrical devices to attenuate the EMI/RFI radiation they emit and to ventilate them at the same time. Many questions have been asked about which perforated pattern should be used to satisfy both of these design requirements
