Surface mount versions of components like many types of inductor transformers quartz crystal resonator temperature controlled crystal oscillators tcxos filters ceramic resonators and the like may require different style packages often larger than the ones that are sued for surface mount resistors and capacitors.

Smd resistor package types. The letters refer to the layers of semiconductor material used to make the transistor. Most transistors used today are npn because this is the easiest type to make from silicon. 3 digit smd resistor codes 4 digit eia 96 smd resistor codes example of smd resistor codes.

There are two types of standard transistors npn and pnp with different circuit symbols. Melf resistor package sizes. The smd resistor packages generally conform to the standard smd outlines for passive smd components.

There is another acronym used that means pretty much the same thing which is smt and that means surface mount technology. Smd resistor chart calculate find the value of smd resistor. Sometimes surface mount resistors are also used as melf packages metal electrode leadless face.

First off smd means surface mount device. There is a growing trend in new designs to migrate towards some of the very small packages where power dissipation allows. The main advantage of using melf in stead of standard smd packages is the lower thermal coefficient and better stability.

Small signal transistors and diodes marking codes diode type number to. Thisll be describing the various packages that an led can come in as well as resistor and the more common capacitor packages as well as many other surface mount devices. These tiny chips are marked with three 3 or four 4 digit codes which is called smd resistor codes to indicate their resistance values.
