What are the specifications and sizes of 0.4 board-to-board connectors? What are the main electrical properties?

0.4 board-to-board connector is a kind of board-to-board connector with the features of miniaturization, high reliability and multi-functionality, which is widely used in electronic equipment. Its specification size and main electrical properties are as follows: 1. Specification size The specification size of 0.4 board-to-board connector is usually described in two parts: plug and socket, where plug refers to one port of the connector and socket refers to another port of the connector. The following are some common specification dimensions: 0.4mm plug: length of 3.6mm, width of 2.0mm, height of 1.0mm, number of pins 40-100. 0.4mm socket: length of 3.6mm, width of 2.0mm, height of 0.5mm, number of sockets 40-100. 0.4mm heightened plug: length of 3.6mm, width of 2.0mm in length, 2.0mm in width, 1.5mm in height, the number of pins is 40-100. 0.4mm heightened sockets: 3.6mm in length, 2.0mm in width, 1.0mm in height, the number of sockets is 40-100. 2. Main electrical properties The main electrical properties of the 0.4 board-to-board connector include the following: Rated Voltage (Rated Voltage): 0.4 board-to-board connector's rated voltage is generally 50V AC/DC. rated current (Rated Current): 0.4 board-to-board connector's rated current is generally 0.5A AC/DC. insulation resistance (Insulation Resistance): 0.4 board-to-board connector's insulation resistance is generally 100MΩ. Contact resistance (Contact Resistance): 0.4 board-to-board connector contact resistance is generally 20mΩ or less. Withstanding voltage (Withstanding Voltage): 0.4 board-to-board connector voltage is generally 200V AC/DC. Operating temperature range (Operating Temperature Range): 0.4 board-to-board connector operating temperature range is generally -40 ℃ to +85 ℃. 0.4 board-to-board connector is a widely used connector, has a small, high-density, high-efficiency, high-efficiency, high-efficiency, high-efficiency, high-efficiency, high-efficiency, high-efficiency, high-efficiency, high-efficiency. The 0.4 board-to-board connector is a widely used connector, featuring compactness, high density, high reliability and so on. Due to its small specification size, easy installation, can adapt to the trend of increasingly smaller electronic products, so it has been widely used. In the actual application, you need to select the appropriate 0.4 board-to-board connector according to the specific application scenarios and requirements.
