A selenium rectifier typically consists of a stack of alternating selenium disks with metal electrodes connecting them. The input AC voltage is applied across the stack, and the rectified output is taken from the ends of the stack. A resistor is often included in series with the rectifier to limit current flow.
What else can I help you with?
Can selenium rectifiers be rebuilt?
Selenium rectifiers, with their metal fins and long lived application in battery chargers and in tube type television sets are not intended to be repaired. Once a rectifier plate becomes damaged or it is burnt (unmistakable stink), the entire assembly should be replaced.
How many moles of selenium in selenium tetra-fluoride?
There is one mole of selenium in one mole of selenium tetrafluoride, as the formula for selenium tetrafluoride is SeF4. Therefore, there is 1 mole of selenium in 1 mole of selenium tetrafluoride.
Can you replace a selenium rectifier with a silicon rectifier?
The short answer is yes, usually. If you are working with an ultra high voltage stack all bets are off. For old stereos, etc. you need to estimate the peak reverse voltage and the current requirements. If you have documentation, use it, otherwise: rule 1. PIV is 30 volts per plate, divided by the formfactor: rule 1a. Formfactors: diode=1, half bridge (center tap)=2, bridge=4. rule 1b. Use the maximum of the above and the input electrolitic working voltage multiplied by 1.4, then round up to the next standard voltage within reason (silicon is cheap). rule 2. Assume 500mA per square inch of a single plate's area. rule 3. You may need to heatsink the new rectifier, especially if the current is over a few hundred mA. rule 4. Replace the electrolitics!!!! If the unit is old enough to have a selenium, they are well past the warentee. rule 5. If the voltage is low (under 10VDC) you may need to put a small valued resistor between the rectifier and capacitor. example: a 12 plate center tapped rectifier 1.5 inches square; 12*30=360V divide by 2 =180PIV area=2.25 square inches which gives a current requirement of a little over one amp so use a 1.5A 200PIV unit.
Is selenium a nonmetal?
Yes. selenium is a non metal

Which rectifier has good efficiency?
bridge rectifier is the best rectifier.
What is the correct name for SeF6?
This compound is called selenium hexafluoride.
