FAQ:
Q: Are you manufacturer?
A: Yes we are manufacturing transformer, coil & choke for more than 17 years in China
Q: Is common mode choke made by machine?
A: No, it is handly made.
Q: What is the smallest diameter of core can you make:
A: the inside diameter is about 5mm to 600mm.
Q: Do you test all before shipment?
A: Yes, the choke are tested 100% before time of shipment
Q: Is the choke meeting our requirements?
A: The samples before mass production shall be sent to you for final approval which can be installed on your PCB for final testing.
Q: All the inductance is in same level?
A: Yes. But the inductance shall be +/-25% due to the fluctuation of core
Q: Can you make the choke with the core from buyer?
A: Yes, no problem
