Rectangular Connectors - Headers, Receptacles, Female Sockets

SQT-136-03-L-5 is a rectangular connector component of the Headers, Receptacles, and Female Sockets group. This particular version is ideal for low frequency applications such as the automotive, medical, industrial, and networking markets.

It is a single-row, press-fit type connector available in thirteen different pin counts, from two to fourteen contacts. Its 3.96 mm board-to-board pitch allows it to perform in a wide range of harsh environments such as humidity or temperatures between -55°C to 150°C. The main features of the SQT-136-03-L-5 connector are its UL 94V-2 insulation material for additional protection, its galvanized brass contacts for warmth and electrical conductivity, and its metallic black color.

Regarding its working principle, the SQT-136-03-L-5 connector provides a mechanical and electrical connection between two or more printed circuit boards to complete the interconnect system. The connection is made by inserting the pins of the connector into the mating holes on the circuit board using a press-fit method. The press-fit operations can be done either by hand pressing or with press-fit fixtures.

The SQT-136-03-L-5 connector has an improved mechanical design that includes a termination point between the tapered rear barbs and the connector body in order to provide a better heat dissipation when compared with similar headers. This greatly reduces conductive heat emission and decreases the risk of board damage caused by heat.

The pins of the SQT-136-03-L-5 connector also feature an angled surface which offers a better contact surface and improved electrical characteristics. This results in a more reliable connection which offers a maximum current rating of 2A per contact.

Another great feature of the SQT-136-03-L-5 connector is its robust construction which is designed to withstand environmental shocks and vibrations, making them suitable for use in harsh industrial and automotive environments. The connector also has an IP67 protection rating and is RoHS compliant.

In conclusion, the SQT-136-03-L-5 connector is an excellent choice for low-frequency applications such as those found in the automotive, medical, industrial, and networking markets. Its robust construction, UL 94V-2 insulation material, and press-fit type connections make it a reliable and economical choice for many applications.
