The BC548 is a general-purpose NPN bipolar junction transistor found commonly in European electronic equipment and present-day designs in Australian and British electronics magazines where a commonly available low-cost NPN transistor is required. It is a part of a family of NPN and PNP epitaxial silicon transistors that include higher-quality variants, originating in 1966 when Philips introduced the metal-cased BC108 family of transistors which became the most used transistors in Australia and taken up by many European manufacturers. The BC548 is the modern plastic-packaged BC108, and can be used in any circuit designed for the BC108 or BC148, which includes many Mullard and Philips published designs.
The BC546 and BC547 are essentially the same as the BC548 but selected with higher breakdown voltages while the BC549 is low noise version, and the BC550 both high-voltage and low-noise. The BC556 to BC560 are the PNP counterparts of the BC546 to BC550, respectively.
The BC548 is low cost and is available in most European Union and many other countries. It is often the first type of bipolar transistor hobbyists encounter, and is often featured in designs in hobby electronics magazines where a general-purpose transistor is required.
Never said that I was perfect
All the crazy things I do
All the loving we made
I wouldn't trade, girl I love you
But falling in love was not the plan
So honey try to understand
The only thing I can do
Is promise to you, that I won't be true
Don't ask me to be Faithful
‘Cos I've tried so many times
I don't think that I am able
All I am is what I lay out on the table
Don't ask me, don't ask me to be Faithful
You know I hate to lie
I don't have a reason why
To hurt you deliberately
Why can't you see, the others
They don't mean a thing to me
Don't ask me to be Faithful
‘Cos I've tried so many times
I don't think that I am able
All I am is what I lay out on the table
Don't ask me, don't ask me to be Faithful
You want the man I'll never be
I'll be yours unfaithfully
I know in time that when you cry you'll realise
My love is not a crime
Don't ask me to be Faithful
‘Cos I've tried so many times
I don't think that I am able
All I am is what I lay out on the table
Don't ask me, don't ask me
