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 ...
Pins and sockets can be arranged in any combination in a single housing, and each housing can be either male or female. 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.
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 .
SOIC-16 A PIC microcontroller (wide SOIC-28) in a ZIF socket. A small outline integrated circuit (SOIC) is a surface-mounted integrated circuit (IC) package which occupies an area about 30–50% less than an equivalent dual in-line package (DIP), with a typical thickness being 70% less.
The tab is located 45° from pin 1, which is typically the emitter. The typical TO-5 package has a base diameter of 8.9 mm (0.35 in), a cap diameter of 8.1 mm (0.32 in), a cap height of 6.3 mm (0.25 in). [1] The pins are isolated from the package by individual glass-metal seals, or by a single resin potting.
The former Soviet Union and Eastern bloc countries used similar packages, but with a metric pin-to-pin spacing of 2.5 mm rather than 0.1 inches (2.54 mm). The number of leads is always even. For 0.3 inch spacing, typical lead counts are 8, 14, 16, and 20; less common are 4, 6, 18, 24, and 28 lead counts.
