How do you identify a SMD transistor?

How do you identify a SMD transistor?

To identify a particular SMD device, first identify the package style and note the ID code printed on the device. Now look up the code in the alphanumeric listing which forms the main part of this book by clicking on the first character shown in the left-menu.

How do you read a SMD capacitor code?

Capacitor Code Format Standard-tolerance SMD capacitors use a 3-digit code to mark the capacitance value on the part. The first two numbers will indicate the significant digits, and the third will be the multiplier. ‘R’ is used to indicate the position of a decimal point.

How do you read a transistor number?

The typical format for the transistor is a digit, letter and serial number. The first digit is the number of leads minus one. An ordinary bipolar transistor has three leads, so the first digit for it will be 2. The letter N is for semiconductors, so this will be the letter written on a transistor using this system.

What is meant by SMD in electronics?

Surface Mount Device (SMD): An electronic component that mounts on the surface of a printed circuit board (as opposed to “through-hole” components which have pins that are inserted into holes).

How do you identify SMD capacitors and resistors?

There are two methods to indicate the resistance value on the SMD resistors’ appearance. 1. In Arabic numbers: the first two numbers indicate the absolute numbers of the resistance value, and the last number means the power of 10. For example, 103 means 10000Ω, 391 means 390Ω, 473 means 47000Ω.

What are SMD capacitors?

SMD or SMT surface mount capacitors are used in high volume manufacture – quantities used are numbered in the billions. They are small, leadless and can be placed onto modern printed circuit boards using pick and place machines used in modern manufacturing.
