FAQ
Q: What are the inductance and current ranges of the TRF series?
A: The TRF series covers inductance from 0.7mH to 100mH (dual winding) and rated current from 0.3A to 8A. The wide inductance range and high current capacity make it suitable for various EMI suppression applications, from signal line filtering to power line filtering. For specific selection, please refer to the datasheet or contact our technical support team.
Q: What are the advantages of the plastic case?
A: The plastic case provides physical protection and environmental shielding. It effectively prevents foreign objects from contacting the windings, improving product reliability in harsh environments. The plastic case also facilitates automated insertion and PCB mounting, offering excellent mechanical strength and vibration resistance.
Q: What does the 1500VAC withstand voltage test represent?
A: The 1500VAC withstand voltage test (between windings, 3 seconds) means the primary and secondary windings can withstand 1500V AC without breakdown, ensuring isolation safety. This parameter is especially important for safety isolation in AC/DC power supplies.
