Q: What is an induction coil, and how does it function in a
circuit?
A: An induction coil, or inductor, is a passive electronic
component that stores energy in a magnetic field when electric
current flows through it. It primarily resists changes in current,
a property known as inductance. In signal systems, it can be used
to tune frequencies, filter signals, or in wireless power systems,
to create or receive an electromagnetic field for energy transfer.
Q: Why should I choose a custom-designed coil over a standard
off-the-shelf part?
A: Standard coils may not meet the specific size, performance, or
efficiency requirements of your unique application. A custom coil
ensures optimal performance by being precisely engineered for your
target inductance, current handling, physical dimensions (O.D.,
I.D., height), and self-resonant frequency, leading to a more
reliable and efficient end product.
Q: What information do I need to provide for a custom coil order?
A: To get started, please provide your key requirements such as:
Desired Inductance Value (e.g., in µH or nH)
Target Operating Frequency or Self-Resonant Frequency
Current Rating and Saturation Current
Maximum Physical Dimensions (Outer Diameter, Inner Diameter,
Height)
DC Resistance (DCR) Limits
Application and Operating Environment
Q: What is your sample policy and production lead time?
A: We support sample development. The sample lead time is typically
7-15 working days after design confirmation. For mass production
(MP) orders, the lead time is generally 10-25 days, depending on
the order quantity and complexity.
Q: How are the products shipped?
A: We offer flexible shipping options to suit your needs, including
express couriers (DHL, UPS, FedEx) for speed, sea freight for
large, cost-effective shipments, and China Post for smaller
parcels.
