Through Hole twin In-line Package

A Ceramic dip IC is a normal dual In-line package that supplies Ceramic instead of Plastic because that the IC body, at a greater cost.

Ceramic protects the IC from greater temperature and humidity conditions.A Ceramic dive is also called a CERDIP. Click the CERDIP because that a bigger view.The graphic above shows a with Hole machine in a Ceramic package.The snapshot below shows various plastic dive sockets.

DIP Sockets

DIP Sockets include; 6-pin, 8-pin, 14-pin and also 22-pin sockets.Note the the IC is a ceramic package in order to have far better thermal characteristics, but the sockets are just molded plastic. The sockets don"t have any kind of electrical characteristics to adjust over temperature. Of food the sockets might be damaged through high heat, but the very same amount of heat would also destroy the board the components are mounted on. For this reason the ceramic parcel is used to defend the junction temperature that the semiconductor which might be damaged by a much reduced temperature than that i beg your pardon would damages the plastic real estate of a dip socket.

The most typically found dive packages have actually an inter-lead spacing (or lead pitch) of 0.1 inch (2.54 mm). And also having a heat spacing varies depending on lead counts, v 0.3 in. (7.62 mm) or 0.6 customs (15.24 mm).

Both passive or active devices may be uncovered using ceramic packages.

Another instance of a ceramic dip is shown as a 8048 uP, with a UV home window on the optimal of the package. Indicating the a semiconductor ingredient made one of two people of plastic or ceramic may have actually a home window to erase a programmed part. Keep in mind that big DIP packages the that dimension made either of plastic or ceramic product are ending up being less common, relocating to PGA or BGA packages .

A comparison between a Ceramic and also Plastic emboldened IC

Editor note; as an observation: usually ceramic packaged IC can be differentiated from plastic packages by sight. In general a plastic packaged IC is jet black, while a ceramic package is a dark gray. Also the whole body that a plastic package is the same shade . If a ceramic package is dark gray however has a lite gray band running roughly the body at the height of the leads of the IC . In addition the plastic body has actually a smother texture 보다 a ceramic body, in that, visually the end up of a ceramic body shows up to be more course. Keep in mind that the graphical illustration at the height of the page is shown in reverse; the human body is displayed as white while the tape is high-lighted with black shading. However the gray band is visible in each of the three photographs offered as ceramic IC examples.

In basic a ceramic part may be a army grade part, for this reason will run through the armed forces temperature range. The common commercial temperature variety is defined between 0 and also 32C, while the military variety extends -55C to 125C. A military component could be identified by a number of different component numbers, however the TTL family would be a 54 part instead of a 74 part, as in 5400 or 7400 quad 2-input NAND gate. There room a few conventions provided with the number is numbered sequence; IC operation Temperatures. Yet the ceramic IC over shows a couple of part numbers, the 883 suggest that the component is qualified to MIL-STD-883 i beg your pardon is another indication that is a DOD component.
