Trebao bih 2 otpornika
Ako ima koja dobra dusa da mi posalje dva otpora koja nisam mogao naci.
To su:
500 Ohma (cistih) x 2
1.4 Ohma (cistih) x 1

Re: Trebao bih 2 otpornika
ja jos ne znam za prljave ome, pa ako ti nije problem objasni...
500 oma mozes dobiti paralelnim vezivanjem 2 otpornika od 1K
1.4 oma mozes dobiti paralelnim vezivanjem nekoliko otpora. ili rednim.
nisi naveo snage tako da mislim da ti niko nece dat te otpornike...

Re: Trebao bih 2 otpornika
... snaga... veličina... išta!
Btw. nestandardne vrijednosti...
Peđa... brz! 1,4 i 1,5 su u 10% tolerancije...
Re: Trebao bih 2 otpornika
Imam te opornike ali ima malo prašine i prljavštine na njima, cini se ta ti to ne odgovara...Black Angel wrote:Ako ima koja dobra dusa da mi posalje dva otpora koja nisam mogao naci.

Re: Trebao bih 2 otpornika
A sada ozbiljno za 500 napravik to što ti je peđa rekao, a za 1.4 stavi ova 3 u seriju

Zaš ti trebaju baš čisti ?

Re: Trebao bih 2 otpornika
Pod "cisti" sam mislio da su tocno te vrijednosti uz vrlo malu toleranciju.
Snaga i velicina moze sta se nade.....
0.25W (najpozeljnije), 0.5W......
Bitno mi je da bude tocno 1.4k jer je boro tako rekao

Re: Trebao bih 2 otpornika
Aj napravit cu 500R sa 2 x 1k a ako netko ima trimer 2k umjesto onog otpora 1.4k bilo bi super.
Ako treba uplatit cu i za trimer i za postansku markicu

Šteta je tog sa 10-ak okretaja utrošiti ovdje

I to što kažeš... ovo je dio data sheeta...
"MUTE FUNCTION
The mute function of the LM4702 is controlled by the amount of current that flows into the mute pin. If there is less than 1mA of current flowing into the mute pin, the part will be in mute. This can be achieved by shorting the mute pin to ground or by floating the mute pin. If there is between 1mA and 2mA of current flowing into the mute pin, the part will be in “play” mode. This can be done by connecting a power supply (Vmute) to the mute pin through a resistor (Rm). The current into the mute pin can be determined by the equation Imute = (Vmute – 2.9) / Rm. For example, if a 5V power supply is connected through a 1.4k resistor to the mute pin, then the mute current will be 1.5mA, at the center of the specified range. It is also possible to use Vcc as the power supply for the mute pin, though Rm will have to be recalculated accordingly. It is not recommended to flow more than 2mA of current into the mute pin because damage to the LM4702 may occur."
Prema tome 1,5k radi... sve kao i 1,4k... samo malo, malo drugčije...
Struja u slučaju 1,5k bude 1,4mA... što je i dalje "at the center of the specified range"

Angel, onih "čistih" 500R ("prljavih" 499R ima u Chip.) predvidi kao jedan 1206 SMD otpor, a na to mjesto staviš 2 kom SMD od 1K jedan na drugoga - kad već nemaš mjesta
Ako 1 SMD trebaš napraviti od 2 ili 3 u seriji, zalemiš ih kao Stonehenge.
