What’s A Trimmer in Electronics?   A Trimmer, or Preset, is a miniature adjustable electrical component. It is meant to be set correctly when installed in some device, and never seen or adjusted by the device’s user. Trimmers can be …

What’s TSOP Package?   Thin Small Outline Package (TSOP) is a rectangular IC package with a thickness of 1.0 mm. The lead counts range from 20 to 48. Thin SOP IC’s are packed in JEDEC trays or tape and reel …

Thin Shrink Quad Flat Package (TSQFP) is a surface-mount IC package with gull wing leads on all four sides of the quad flat package (QFP) body. The lead pitches are always 0.30mm, 0.40mm, 0.50mm or 0.55mm with height equal to or less than 1.60mm. …

Thin Shrink Small Outline Package (TSSOP) is a rectangular surface mount plastic integrated circuit (IC) package with gull-wing leads. They are suited for applications requiring 1 mm or less mounted height and are commonly used in analog and operation amplifiers, …

Tube and Tray Component Packaging styles are similar in that they allow for the safe storage and transport of larger parts that do not fit comfortably in Tape-and-Reel Packaging. Compared to Loose and Bulk Packaging, where the components are stored …

In electronics manufacturing, Turnkey or Turn-Key, is a type of outsourcing method that turns over to the subcontractor all aspects of manufacturing including material acquisition, assembly and testing. Its opposite is consignment, where the outsourcing company provides all materials required …

The vertical bending of gull-wing leads.

Twist references the flatness of a printed circuit board where not all four corners of the board are able to touch at the same time on a flat plane. See Bow.

What’s UCSP Package?   Micro (μ) or Ultra Chip Scale Package (UCSP) is a packaging technology that eliminates the traditional plastic package used to encapsulate integrated circuits (ICs). Soldering the silicon directly to a PCB saves board space, but at …

What’s UJT?   A Unijunction Transistor (UJT) is a three-lead electronic semiconductor device with only one junction that acts exclusively as an electrically controlled switch. The UJT is not used as a linear amplifier. It is used in free-running oscillators, …
