There are a few odd things about F007C. If you look at the specs
Peak Reverse Voltage:40V
DC Forward Current:100mA
Power Dissipation:1W
Package / Case:PBPC-6
Emitter Voltage VCEO Max:1.2KV
Gate-Emitter Leakage Current:100nA
Why would there be VCEO?
Hello
I have an old power supply circuit which I am trying to repair/ replace. It has an Op Amp F007C. I have tried to Google F007c but I am unable to get it's datasheet. Due to this I cannot understand I cannot check the board/ unable to figure out what voltage output the supply should give...
Hi. I have run into a strange problem. I am using PIC18LF1220. The microcontroller is working fine except pin RB2. I have configured RB2 as input but it always reads 0 volts. To eliminate possibility of (hardare) PCB problem, I bent the RB2 pin so now its not touching the PCB. Then I am applying...
I have a paper cutter knife that runs on 24 volts which is controlled by microcontroller running at 3.3 V. DO-Cut Signal is attached to microcontroller pin. The pin goes high and low but the CN-CUT signal remains at 24 volts. I think there is some problem in resistor values. Can anyone help with...
I am using PIC18LF1220. The output functions (on PortA) work fine, however, the input functions on PortB are not working. I have checked hardware connections to Pin and they are fine. I think I am missing something in the code. My code is as below.
#include <hitech.h>
#include <stdio.h>...
Very interesting. How can you check resonant frequency?
Since its part of printer, it should support both read and write operations. Therefore, it cannot be 125khz as they are write only. The other possibility is 13.56Mhz but my reader does not see it as a RFID tag (reader works fine with other...
Hello Everyone
We have a OKI C711 printer attached to university network and almost every week, we change the toner cartridges. The old cartridges are a waste and are disposed off. However, recently I found these chips in the cartridges which look like RFID chips. Since I can get 4 of these...
