Wide Temp Common Mode Inductance TRF2606H-103Y -40°C to +105°C for Automotive Electronics and Industrial Control

The TRF2606H-103Y common-mode inductance is designed for common-mode noise suppression in AC/DC and DC/DC power lines. Inductance is 11.5mH minimum, rated current is 4A, and rated voltage is 250VAC. The product features low DCR, effectively reducing power loss. Withstand voltage tests: 1000VAC/50Hz/5mA/3 seconds (coil to core) and 1500VAC/50Hz/5mA/3 seconds (N1 to N2), ensuring high-voltage isolation safety. It is widely used for common-mode noise suppression in switching power supplies, communication equipment, automotive electronics, and industrial control applications.

Q: What is the withstand voltage rating of this product?

A: The withstand voltage test has two levels: 1000VAC/50Hz/5mA/3 seconds (coil to core) and 1500VAC/50Hz/5mA/3 seconds (N1 to N2). The high withstand voltage levels ensure safe isolation in AC/DC power supplies, preventing breakdown between windings.

Q: What applications can the 4A rated current meet?

A: The 4A rated current is suitable for small to medium power AC/DC adapters, DC-DC converters, communication equipment power supplies, and industrial control equipment. When selecting, we recommend choosing a rated current at least 1.2 to 1.5 times the maximum operating current to prevent core saturation, which would reduce filtering performance.

Q: How long is the delivery time and what packaging methods are used?

A: The standard lead time is 2-8 weeks after order confirmation, depending on product specifications and order quantity. Products are securely packed with cartons, foam, pallets, wrapping film, and fixing straps to ensure safe international transportation.
