SMD units lead production. Releases come in types A, B and C.
China's selection of USB 3.1 connectors consists of types A, B and C in male, female, SMD and DIP configurations, with the first leading production. The products come in 5, 12 and 20V rated voltage, and 1.5, 2, 3 and 5A rated current. These have copper alloy contacts with gold plating, steel shell and UL94V-0-rated thermoplastic insulators. All models comply with RoHS requirements.
The key materials such as copper, gold, nickel, tin and plastic are sourced locally. A number of manufacturers also purchase thermoplastic from overseas providers.
The cost of manufacturing inputs has been stable, keeping prices unchanged. Most companies project this trend will persist in coming months.
