High Precision EI25 Current Transformer

Transformer: The "Current Translator" Hidden in the Circuit Board Disassemble any power adapter. The black "small steel bar" on the circuit board is the core of the EI25 transformer - it is not an ordinary iron block, but the ei transformer core (ferrite core). This magnetic core is like an intelligent purifier: when a large current passes through, it can instantly absorb the high-frequency noise in the power supply and filter the dirty and messy current as clear as mountain spring water.   As a member of the Current Transformer family, the unique skill of EI25 is to safely "translate" dangerous large currents (such as 10A) into small currents (such as 0.1A). The three capabilities that engineers love most about it:     Ferrite cores have excellent anti-interference performance - they can completely absorb the high-frequency noise of switching power supplies. High-temperature resistant without malfunction - Even if the power chip is heated to 80℃, it remains as stable as an old…
