PTC19DBCN headers are rectangular connectors typically used for wire-to-wire and wire-to-board connections. Headers are generally available in 2 to 40 positions with plastic or metal substrate options. The PTC19DBCN is a 2.54mm pitch, 19-pin header with a dual row design. It is compatible with most common mating receptacles, including the ZX14-E01-E02 (19-pin) series.

The electrical performance parameters for the PTC19DBCN header are mainly affected by its contact resistance, dielectricwithstand voltage, insulation resistance, and contact current rating. The contact resistance of the PTC19DBCN header is typically 15 Kohm maximum. The dielectricwithstand voltage ensures the correct signal conduction in the connection. The typical dielectricwithstand voltage of the header is 500VAC. The insulation resistance is typically 1.0Ω, with a minimum dielectric strength of 250VAC. Moreover, the contact current rating is 3A (maximum).

The mechanical performance parameters of the PTC19DBCN header can be divided into three categories: mounting, mating, and shell. In terms of mounting, the PTC19DBCN header has to meet the Flat-to-Flat (FTF) standard (with a maximum deviation of 1.6mm). In terms of mating, the electrical contacts of the header must have a strong adherence and good clamping forces. The PTC19DBCN has a mating durability rating of 100 cycles, with a minimum contact retention force (CRF) of 5N. In terms of shell, the PTC19DBCN header has to meet the IEC 61076-2-101 standards. Specifically, it must have shock resistance, vibration resistance, and corrosion resistance.

The working principle of the PTC19DBCN header is simple. First, the header is mounted onto a printed circuit board (PCB). Next, the contacts on the header are connected to the respective conductors on the PCB. The corresponding male pins on the mating connector are then inserted into the contact’s slots on the header, thus creating a secure electrical connection. Additionally, the secure lock on the connector ensures that the two connectors are properly mated. The PTC19DBCN header is thus able to provide reliable signal conduction from the source to the destination.

In conclusion, the PTC19DBCN headers are reliable rectangular connectors, typically used for wire-to-wire and wire-to-board connections. The electrical parameters of the header comply with international standards, and its mechanical parameters provide a secure connection between the two connectors. Furthermore, its simple working principle makes it an ideal choice for a wide range of applications.
