STMicroelectronics’ IPS8160HQ and IPS8160HQ-1 new high-side switches provide eight channels in a compact QFN48L package — with the added value of built-in protection and diagnostics. This unique combination of features saves space and enhances reliability in PLC modules used for driving heavy loads and unidirectional motors in vending machines. Additional applications for the new switches include I/O peripherals…
What is EMC?
EMC stands for Electromagnetic compatibility, which means that a device is compatible with (i.e., no interference is caused by) its electromagnetic (EM) environment. It does not emit levels of EM energy that generate electromagnetic interference (EMI) in other devices in the vicinity. Electromagnetic interference (EMI) is the interference caused by one electrical or electronic device…
What are EMS/EMC immunity lab tests?
EMC test is known as Electromagnetic Compatibility, a certification for electronic devices to maintain their limitation of electromagnetic waves. As discussed in the previous article, there are two types of EMC tests – emission (EMI) and immunity (EMS). EMI (Electromagnetic Interference) tests measure the magnetic waves emitted by the device, and EMS (Electromagnetic Susceptibility) tests…
What are some common EMI/EMC tests?
An EMC test is known as Electromagnetic compatibility, a certification for electronic devices to maintain their limitation of electromagnetic waves. As discussed in the previous article, there are two types of EMC tests: emission (EMI) and immunity (EMS). EMI (Electromagnetic Interference) tests measure the magnetic waves emitted by the device, and EMS (Electromagnetic Susceptibility) tests…
How to perform an EMI/EMC pre-compliance test
EMC testing is essential to get a certification of Electromagnetic Emission and Immunity test before launching the product in the market. However, actual EMC tests are pretty expensive. Before going for the actual EMC test, the product should test in EMC pre-compliance test Lab. Pre-compliance testing will mimic all tests performed at EMI/EMC test labs…
EMS/EMC Pre-Compliance immunity test
In the previous article, we learned about EMI/EMC pre-compliance test. EMS/EMC pre-compliance immunity test is required before the compliance test. EMS/EMC pre-compliance immunity test will give the confidence to pass the compliance test. The pre-compliance immunity test simulates all the tests done at the compliance test lab, but it is unnecessary to apply all the…
