List two specifications for the electronic system within the structure EMI shield
1. The electronic system within the EMI shield should have a shielding effectiveness of at least 90 dB (decibels) to protect against electromagnetic interference (EMI) from external sources.
2. The electronic system should have a frequency range of at least 10 kHz to 1 GHz to effectively shield against EMI in a wide range of frequencies commonly encountered in electronic devices.
1. Material Composition: The electronic system within the structure should have an EMI shield made from a conductive material, such as copper or aluminum. This ensures that it effectively blocks electromagnetic interference (EMI) from entering or leaving the system.
2. Shielding Effectiveness: The EMI shield should have a specified level of shielding effectiveness, usually measured in decibels (dB). This indicates the extent to which the shield can attenuate or block EMI. Higher shielding effectiveness values indicate better EMI protection for the electronic system. Common shielding effectiveness targets for electronic systems range from 60dB to 100dB.
To find the specifications for the electronic system within the structure EMI (Electromagnetic Interference) shield, we can look into the requirements and characteristics usually associated with EMI shielding. Here are two common specifications:
1. Shielding effectiveness: This specification indicates the ability of the EMI shield to block electromagnetic radiation and prevent it from interfering with the electronic system. Shielding effectiveness is typically measured in decibels (dB) or as a percentage of electromagnetic energy blocked. Higher shielding effectiveness values indicate better protection against electromagnetic interference.
2. Frequency range: The EMI shield system should be designed to attenuate electromagnetic radiation across a specific frequency spectrum. The frequency range specification defines the minimum and maximum frequencies that the shield can effectively block or reduce electromagnetic interference. It is important to ensure that the shield covers the frequency range relevant to the electronic system's operation or the interference it is meant to prevent.
These two specifications are essential in assessing the performance and suitability of an EMI shield for a given electronic system. It is worth noting that additional specifications, such as material durability, ease of installation, and environmental factors, may also be relevant depending on the specific application and requirements.
