HTSW-118-21-F-D, a type of rectangular connector – headers, male pins, provides an electrical interconnection between the device and the printed circuit board (PCB). It is widely used in consumer products, automotive and telecommunication fields, because of its small-sized, lightweight and low cost advantages.

The header has two types: solder type and self-mating type. Among them, the solder type has two common subtypes: right angle and straight. In addition, the header is divided into single row and double row according to the number of pins. The (S)MALL-112-21-F-D type is a double row, right angle, solder type header.

SMALL-112-21-F-D has a set of compliant pins designed for additional anti-vibration performance, enabling tight connection between the device and the PCB. It is designed and optimized to withstand vibration of up to 3G at 10-2000 Hz. It is a reliable solution for automated manufacturing systems such as reflow soldering and wave soldering.

Its operating temperature range is -40℃～+105℃. Its durability is good, with minimum engagement/disengagement cycles of 10,000 times in operations. It is widely used in areas with high safety requirements, such as automobiles, aerospace and medical equipment, ensuring performance operation in harsh environments.

The wiring size is 1.2mm. Using high-precision contact technology, it has a maximum current of 1A and a contact resistance of 12mΩ (maximum). The mating force is 0.6N (maximum), and the withstanding voltage is 100V

SMALL-112-21-F-D is widely used in the automotive, telecommunication, home appliance, consumer electronics and instrumentation industries. It can be used in PCMCIA, PCI, audio, and other portable interfaces

The working principle of the SMALL-112-21-F-D is simple. The header has two parts: the female connector and the male pin. The female connector is connected to the PCB, while the male pin is connected to the electronic device. When the male pin is inserted into the female connector, current is carried through the connection and the two devices are electrically connected.

When the male pin is inserted into the female connector, the compliant pins provide a secure connection with very low mating force, ensuring reliable electrical connection while still allowing for easy mating and unmating. Moreover, the compliant pins can withstand vibration thus providing additional reliability.

The SMALL-112-21-F-D is a popular rectangular connector – headers, male pin – that is used in many industries for its small size, low cost, durability and reliable electrical connectivity. It can provide a secure connection with very low mating force, ensuring reliable electrical connection while still allowing for easy mating and unmating. Its compliant pins are designed to provide additional anti-vibration performance, ensuring long-term reliable performance in harsh environments.
