The performance parameters of network transformers are divided into three parts: electrical performance, mechanical performance and environmental performance.
Electrical performance contains:
1. insertion loss (IL)
2. return loss (RL)
3. crosstalk (Crosstalk) 4. common mode rejection ratio (CMRR)
4. common mode rejection ratio (CMRR)
5. Open Circuit Inductance (OCL)
6. Turn Ratio (T/R)
Mechanical properties include:
1. Solder ability
2. Resistance to soldering heat
3. Vibration
4. Mechanical Shock
5. Flatness (in case of SMT modules)
Environmental performance is included:
1. Thermal Shock
2. Temperature Life
3. Humidity/Temperature Cycling
