Electronics Forum / Components / February 2006

Dear Member,
We are an 8 Years company strong in supply the electronic component of
different brand name.
Our services including the OEM manufacturing and electronic components

Looking for a 5 v relay for a robotic toy, looking for what product would
have one, We have many discarded electronics to look at.

Is there a way to discover the pinout for unknown transistors with a
multimeter? Without damaging them? Even if you don't know whether it's
a jfet or pnp, etc? This one is a Telefunken OC603 with a dot next to
one of the legs. Sometimes you can find a datasheet on obsolete

I recently bypassed my vehicles electrical system for my headlights and
now my vehicle comes up with headlight out warnings.  I have been told
if I installed resisters in the original wiring to simulate the load of
the light bulbs then my problem will go away.

i want to test a 24xx32A serial EEPROM. Can you tell me a way to input
serial
data and how i can observe the output?
Thanx in advance

I'm looking to make a portable battery pack (12V lead-gel battery and 9V
step-down switching reg) to power a Nikon DSLR. The Nikon docs state
that the 4-pin DC-in connector is an "industry standard DC connector".
While it looks familiar somehow I couldn't find anything like it in ...

Can anyone direct me or advise of any schematics, examples etc of what is
required to build up a device that I can use to interface with the compact
flash port of a PDA.
Many thanks

Hi , I m looking for a STI5508 OMEGA-PVR IC.
THis is to repair a Bell ExpressVU receiver model 5900.
Tks./...

Hi I am trying to repair an old Technics AM-FM receiver which has an
AN217P IC and an AN363 N IC does anyone know what the pin data is as it
is not available anywhere on the net.
Thanks ...Arachnid

I want to create an electronic weigh scale measure upto 100kg
which loadcell,microcontroller,Lcd driver display are easy for me to
make it.
I need all datasheet part no.

hi, how does one decide the operating frequency of a crystal oscillator
required for a PIC18F452? is there any relation between the supply
power and the frequency?
the datasheet seems confusing.

I have a momentary contact switch.
I want to find more.
But, this is not an ordinary momentary contact switch.
Inside it has a rubber plunger attached to the acuator.

I'm looking at a circuit based on an NE570 compandor chip (as described in
http://www.semiconductors.philips.com/pip/NE570D.html).  A couple questions
arise:
1. What are the key differences between the NE570, NE571, and SA571?  They

anyone know the basic spec for this one? Thank you.

Anyone know the part number for this mosfet? It has a circle with "H1"
inside
The biggest Mosfet on the top of the picture.
