1. Miniaturization and Surface Mount Design
Compact Size: SMD package, much smaller than traditional plug-in current transformers, suitable for high-density PCB layout.

Automated production: can be directly through the SMT (surface mount technology) welding, improve production efficiency and reduce labor costs.

2. High accuracy and low error
High linearity: good linear relationship between output signal and input current within the rated current range, typical error range ±1%~±3%.

Low phase difference: optimized design to reduce phase shift, especially important for AC signals (such as power metering).

3. Wide Operating Parameters
Wide Current Range: Typically supports current detection in the milliampere (mA) to tens of amperes (A).

Wide Frequency Bandwidth: Suitable for 50/60Hz industrial frequency, some models support kHz level high frequency (e.g. switching power supply applications).

4. Low power consumption and high isolation
Passive sensing: relies on the principle of electromagnetic induction and does not consume power itself.

Electrical isolation: the primary side (measured current) and the secondary side (output signal) are insulated, and the withstand voltage can reach several kV, to ensure the safety of the circuit.

5. Application Scenarios
Electricity metering: smart meters, energy monitoring systems.

Power management: current protection and feedback in switch-mode power supply (SMPS), inverter, UPS.

Industrial electronics: motor drive, inverter, PLC current detection.

Consumer electronics: miniaturization design of chargers and adapters.
