FAQ
Q1: What types of magnetic components can you customize?
A: We offer complete OEM and ODM services for high-frequency transformers, low-frequency power transformers, common-mode inductors, power inductors, ring coils, flat wire inductors, filter reactors, and multi-winding coils. Support through through-hole/solder pad (SMD), vertical/horizontal installation, optional EE/EI/PQ, ring ferrite or silicon steel core. Widely used in switching power supplies, new energy chargers, industrial control, medical equipment, and solar inverters, etc.
Q2: What technical parameters need to be provided when making the quotation?
A: You can provide electrical parameters (inductance value mH/uH, DCR, Isat, turns ratio, operating frequency, withstand voltage value), size drawings, physical samples, operating temperature range, environmental requirements, and annual order quantity. If only the application scenario is provided without the complete specifications, our engineers will design a solution for you for free.
Q3: Can I customize the inductance value, DC resistance (DCR), leakage inductance and insulation voltage?
A: All electrical parameters can be adjusted. We offer inductance tolerances of ±5%, ±10%, and ±20%; we use multi-strand Litz wire to reduce DC resistance and heat generation; we control leakage inductance for high-frequency transformers; the insulation withstand voltage can be selected from 1kV to 5kV.
Q4: Can I customize the pin type, wire length and installation structure?
A: Yes. We support vertical/horizontal through-hole, SMD base, extended leads, custom wire color, insulating sleeves, vacuum impregnation, epoxy resin casting, metal shielding casings, and customer-specific part number silk-screening, etc.
Q5: Will the unit price be lower if the order quantity is larger?
A: We use a tiered pricing approach. The larger the order quantity, the lower the raw material costs for the cores and wires, and thus the unit price decreases accordingly. Long-term cooperative customers can enjoy additional annual discounts.
Q6: If I only have the requirements for the equipment application, can you provide the design drawings?
A: We offer free development services for magnetic component solutions. Our engineers will generate circuit diagrams, winding specifications and size drawings based on the power, frequency and size limitations of the equipment. After confirmation, samples will be produced.
Q7: What tests will be conducted before shipment? Can test reports be provided?
A: 100% comprehensive inspections will be carried out for inductance, DC resistance, withstand voltage, on-off capability and appearance; sampling inspections will be conducted for aging, high and low temperature cycling, salt spray, and vibration. Corresponding quality inspection reports for each batch of goods can be attached. The complete inspection data for long-term cooperative customers will be archived for a long time.
Q8: Can I choose different magnetic core materials?
A: All series of magnetic core materials can be selected: manganese-zinc ferrite and nickel-zinc materials are suitable for high-frequency scenarios; iron-silicon-aluminum and iron powder cores are used for large current inductors; cold-rolled silicon steel sheets are used for low-frequency transformers.
