1×6 pin header (one row) 1×6 female header (one row) A pin header (or simply, header) is a form of electrical connector. A male pin header consists of one or more rows of metal pins molded into a plastic base, often 2.54 mm (0.1 in) apart, though available in many spacings. [1] Male pin headers are cost-effective due to their simplicity.
Populated (rear) and unpopulated (front) TSOP land patterns on a printed circuit board. A row of through-holes acting as the footprint for a pin header.. A footprint or land pattern is the arrangement of pads (in surface-mount technology) [1] or through-holes (in through-hole technology) used to physically attach and electrically connect a component to a printed circuit board.
The metric codes still represent the dimensions in mm, even though the imperial size codes are no longer aligned. Problematically, some manufacturers are developing metric 0201 components with dimensions of 0.25 mm × 0.125 mm (0.0098 in × 0.0049 in), [ 31 ] but the imperial 01005 name is already being used for the 0.4 mm × 0.2 mm (0.0157 in ...
JST manufactures numerous series (families) and pitches (pin-to-pin distance) of connectors. [ 2 ] [ 3 ] JST connectors are used in many types of products, and commonly used by electronics hobbyists and consumer products for rechargeable battery packs, battery balancers , battery eliminator circuits , 3D printers , and radio controlled servos .
There are three typical pin sizes: 1.57 mm (0.062 in), 2.13 mm (0.084 in), and 2.36 mm (0.093 in). The 1.57 mm pin can carry 5 A of current, while the 2.36 mm can carry 8.5 A. Because the pins have a large contact surface area and fit tightly, these connectors are typically used for power.
The male PCB connector on the 3½-inch floppy drive is normally a polarized right-angle male header, which is a TE Connectivity / AMP 171826-4, [4] the straight model is AMP 171825-4. [ 5 ] The shape of the connector housing makes it very easy to determine the pin number allocations by visual inspection.
The size of the Mini Small Outline Package is only 3mm × 3mm for the 8 and 10 pin versions [1] and 3mm × 4mm for the 12 and 16 pin version. [2] [3] The small package offers a small footprint, short wires for improved electrical connections, and good moisture reliability. [1] Some versions have an exposed pad on the bottom side.
TSOPs are rectangular in shape and come in two varieties: Type I and Type II. Type I ICs have the pins on the shorter side and Type II have the pins on the longer side. The table below shows basic measurements for common TSOP packages. [3]
