Rectangular Connectors - Headers, Receptacles, Female Sockets: Application Field and Working Principle

Rectangular connectors, commonly referred to as headers, receptacles, and female sockets, are small, but complex, connectors used in a wide range of applications. Often used in medical, automotive, and consumer electronics industries, the connectors are employed for a variety of purposes, from interconnecting digital components to powering power circuits, and from sealing electrical shields to providing code specific code switches for medical instruments (i.e. ECG/EKG).

The PPTC251LFBN series is one type of rectangular connector. This series is commonly used in medical field as a power supply connection, especially in high temperature environment. The main feature of PPTC251LFBN series is its low voltage capability to meet power requirements and current rating up to 1A. Other features include compact size, low profile, stripped ends, and the ability to mate with most types of mating parts.

The working principle of PPTC251LFBN series is based on the parallel plate capacitance theory. It consists of two planar plates positioned very close together, separated by an insulating layer. One of the plates is made out of metal and the other is made out of an insulating material. When voltage is applied to the two plates, an electric field is generated and produces a capacitive effect. This causes current to flow through the connector, allowing for the transfer of power to the connected device.

The connector can withstand temperature up to 105°C, and the rated current is up to 1A. The contact area is characterized by high reliability due to its metal pre-tensioned contacts, and its low profile design makes it ideal for high density applications. The PPTC251LFBN series also features a PCB mount design, which makes it easy to install and secure within a PCB board.

The rectangular connectors of the PPTC251LFBN series are versatile and widely used in many applications for their high performance properties. They are now a preferred choice in many areas such as automotive, medical, home appliances, and consumer electronics. In addition, with their wide range of configurations, PPTC251LFBN series connectors ensure an optimal fit for specific applications.

To conclude, the PPTC251LFBN series is a reliable and versatile connector that is suitable for many applications, ranging from medical power supply connections to automotive electronics. With its low profile design, metal pre-tensioned contacts, and high temperature capabilities, the receiver is able to function in a variety of environments, providing a secure, efficient, and cost effective connection.
