The BC548 is a general purpose epitaxial silicon NPN bipolar junction transistor. It is used for amplification and switching purposes.The maximum DC current gain is 800. 

Order Code : RDL/TRB/13/001/V1.0

 It is a 3mm diameter round head, 2 pin terminal for reliable connection, it can create bright red LED light.Ideal for color displays, indicators, diagnostic or analytical equipment and etc.

Order Code :  RDL/RED/13/001/V1.0

 A diode is a two-terminal electronic component with asymmetric conductance; it has low  resistance to current in one direction, and high  resistance in the other direction.

Order Code : RDL/DIN/13/001/V1.0

It is a 5mm diameter round head, 2 pin terminal for reliable connection, it can create bright red LED light.Ideal for color displays, indicators, diagnostic or analytical equipment and etc.

Order Code : RDL/RL5/13/001/V1.0

This is an IC base for 28 Pin IC's. This is used as a place holder for the 28 pin IC chips and is used in order to allow safe removal and insertion of IC chips because IC chips may become damaged from heat due to soldering.This base is very useful for your circuit because if your IC burns out you can easily change the IC without the need of desoldering. 

Order Code : RDL/28PB/13/001/V1.0

DB9 ports are very common on most types of microcontroller, where they can be used to communicate with a PC or other serial devices.

Order Code : RDL/DBFP/13/001/V1.0

DB9 ports are very common on most types of microcontroller, where they can be used to communicate with a PC or other serial devices.

Order Code : RDL/DBMP/13/001/V1.0

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors act to reduce current flow, and at the same time, act to lower voltage levels within circuits. In electronic circuits resistors are used to limit current flow, to adjust signal levels, bias active elements, terminate transmission lines among other uses.
