In contemporary society, a bunch of information is crowded our life, same as the product information. Coilmaster understands that some time is really difficult to find the suitable component for your applications, there are thousands of choices for our product. Even the same characteristic, normally will get 2~4 kinds of product that could meet the requirement, however, what is the best product to fit your applications?
This is what we could help with, we are not only the manufacturer, we are glad to help you to understand what is the difference between each product series, and what may cause the change if you use the wrong part on your applications. Take shielded inductors as examples, in the same dimension, we will have traditional winding series, SDS / SDC, molded type SEP series even the semi-shielded inductor SQH series. But how to choose the most suitable and economical part of your application?
Furthermore, the lead time issue has become more critical since the end of the year 2020.
Many well-known manufacturers currently have lead times of over 20 weeks even one year, often with product allocation policies. Coilmaster could help you to solve this shortage issue, with a lead time of 5~8 weeks excluding the public holiday.
We also could help you to provide the alternative for the EOL / discontinued inductors. And you do not have to wait 20 weeks due to allocations, our lead time is around 5~8 weeks only (excluding the holiday). If for urgent case, we still offer special fast program service with a little extra cost but could deliver the goods to you in 2~4 weeks. Our product range could cover around 90% of all passive components including Murata, Sumida, TDK, Coilcraft, Wurth, Bourns, Vishay, Panasonic, Yageo, and others.

Our vision and product scope
To be the top SMD Power Inductor, Power Choke, Common mode choke supplier in the world, we constantly improve our production instrument to reach the zero defect. Zero defect at Coilmaster is not the slogan, it is a state of mind. Over the past years, Coilmaster invests the few million dollars to achieve this goal. From automated producing line to the testing machine.
Moreover, here is the brief information about our production capacity.
Except for the standard lead time, Coilmaster Electronics also supports the Quick Delivery program, this service provides the limited volume of standard products with lead times from 15~25 days. This service will help our customers to have a prototype in the shortest time and seize business opportunities.
