The PTC17DFBN is a part of the rectangular connectors and male pin family. This type of connector is an important component in PCB design for the majority of electrical and electronic applications. The PTC17DFBN offers superior performance characteristics and an excellent connection in a variety of applications. The connector design of the PTC17DFBN contains a pin-and-socket arrangement, and the contacts are compliantly attached to the circle of the insert to ensure a positive electrical connection. It has a two-row, dual-block design with an overall width of 0.9 mm and a total length of 17 mm. Displayed in a black, fast-on machined contact, the PTC17DFBN is PoP ready and mateable/dismateable from the top side of the PCB. The PTC17DFBN is mechanically design to optimize its contact force and reduce its insertion and extraction forces. Within the connector, a pair of integral barbs locate the spring fingers parallel to reduce bowing. This results in a lower touch current in the contact. All of the parts can accommodate multiple mating cycles with low insertion force. This connector is suitable for a high packing density due to its small size and compatibility with surface mount technology.The PTC17DFBN is UL approved for proper and safe operation in a wide variety of electrical and electronic projects. The contact pins are of dual flush design and manufactured from phosphor bronze alloy. This type of material has excellent electrical conductivity and it is resistant to oxidation. The contact pins are rated for 0.55A/contact at rated voltage and 8A/contact max. The pins are designed to withstand up 6mΩ of contact resistance and can operate in temperatures from -25°C up to 85°C, making it suitable for many different application scenarios.The working principle of the PTC17DFBN is based on its contact resistance. The contact resistance is the sum of the resistance that develops between the contact surface and the mating surface, and the resistance that develops along the contact surface. The contact resistance depends on the contact force, contact geometry, surface finish and materials used. The contact force of the PTC17DFBN is higher than most other connectors due to its dual-block design, thus ensuring a reliable electrical connection at all times.In conclusion, the PTC17DFBN is a great option for electrical and electronic applications due to its reliable contact resistance, UL approval, dual flush contact pins and superior performance overall. Its two-row, dual-block design allows for a high packing density, and its low insertion/extraction forces make it suitable for multiple mating cycles. With its superior performance, the PTC17DFBN is an excellent choice for PCB design.
