Hello.I want to replace my 6 laptop cells which are Sanyo NCR18650BF 3350mAh - 4.9A and i am thinking either
BAK N18650CP 3350mAh - 6.5A or
LG INR18650-M36 3450mAh - 5A.
What do you suggest?
Hello.I am having an fm oscillator that gives around 5 to 7 dbm.I want to drive a MSA0886 with it in order to get around 16dBm.The datasheet of MSA0886 says that output power at 1dB Gain compression is 12.5dBm.So I shouldnt exceed this output power level at MSA0886 in order not to produce signal...
In the datasheet says input sensitivity minimum 12mV ,maximum 300mV.Does that mean that for a TSA5511 can have minimum sensitivity 12mv and another TSA5511 can have a minimum sensitivity of 200mV?
Hello.I have a VCO with +4dbm output at 50 ohm load. What is the min and max input sensitivity of RF IN1 pin 15 OF TSA5511 and what is its impedance?I am thinking of using a resistor attenuator of -5db to feed pin 15 .
In the past when i was feeding pin 15 with -7dbm it wouldnt lock,it needed...
I have already teared down the plastic and measured individual cells at different times.when fully charged,when laptop shuts down, and at middle.all voltages are equal and as expected.
when fully charged each cell is at 4.12V, when fully discharged is at 2.78V and at a middle state all voltages...
Power supply of +/-15V is fine.I dont know why they say +/-5V max.
Yes input R of about 9.1K is a bit on the low side but i think it is ok for modern equipment.Maybe the 9.1K its not suitable if i used a receiver or a cassete deck of 70s-80s. A more appropriate value would be 47K but going...
Hello.This is the datasheet of the uf4004:
https://datasheet.octopart.com/UF4007-Diotec-datasheet-113245491.pdf
I Dont know how to model these parameters for a transformer in Ltspice
Hello.I am making a simple 0.5A /35V psu with a 24Volt AC transformer ,4 diodeS UF4002 and a 2200uF capacitor. I was considering the initial charge current and if the diodes are ok to handle it or should i move to something like HER205? Simulating with a 100 ohm load to get an idea of the...
Hello.I dont know why the designer uses 18cm RG178 coax cable instead of a coil.its not my design.Maybe it has better stability than a coil since its inductance doesnt change when you get close to it.
The oscillator is tested and working.
Another point i dont understand is the use of the...
Hello and thank you all for answering.Looking at the datasheet of TSA5511 the reference frequency of the phase comparator derives from the frequency of the external crystal divided by 512 so for a crystal of 3.2MHZ the reference frequency is 6.25Khz as you said so the values of the first...
Hello.I have this PLL loop filter around Tsa5511 and i have some questions.
What is the role of the circuit after uA741?
I also have an almost same circuit but with different values for the parts inside the red circle.
R26,R27=1K5
R28=680
C32=200nF
C33,C34=100nF
Which of the values perform...
Hello I am having an Asus Xonar dx sound card with pci-e x1 interface.Is there a converter from alliexpress or ebay to connect the card to the usb port of my laptop and use it as external?
