The purpose of certifying a product with capacitors and resistors for RF disturbance testing is to ensure that the product meets the required standards for electromagnetic compatibility (EMC). This testing helps to determine if the product's components, such as capacitors and resistors, are able to mitigate or suppress the effects of radio frequency interference.
RF disturbance testing involves subjecting the product to various electromagnetic fields, both radiated and conducted, at different frequencies and power levels. This is done to simulate real-world conditions and determine if the product's capacitors and resistors are able to withstand and suppress any interference that may occur.
Some common standards for RF disturbance testing include FCC Part 15 for products sold in the United States, EN 55022 for products sold in Europe, and CISPR 22 for products sold internationally. These standards specify the maximum allowable levels of electromagnetic interference that a product can emit.
If a product fails RF disturbance testing, it may need to be redesigned or modified to include more effective capacitors and resistors. It may also need to undergo further testing and evaluation to determine the cause of the failure and how it can be resolved. In some cases, the product may not be able to be certified for sale until it meets the required standards.
No, RF disturbance testing is necessary for all electronic products that emit electromagnetic radiation. Capacitors and resistors are just two components that are commonly tested due to their role in mitigating RF interference. Other components, such as filters and shielding, may also be tested to ensure the product meets EMC standards.
