HVB Ceramic Resistors

㈠Introduction:

   Ⅰ KWX’s HVB Resistor series are  primarily designed for high voltage,power charging/discharging  circuits,surge energy applications and conform to RoHS directive and lead-free.
   Ⅱ For customed designs,tighter tolerances,non-standard technical requirements,or custom special applications,please contact our sales for more information.
   Ⅲ The HVB is perfect for medical defibrillators.
   Ⅳ Surface insulation optional palm red or green.
   Ⅴ Compared with HVA,the HVB offers more choices for customer.

㈡Features： 

  Ⅰ Special  ceramic resistor , was made of Clay , Silicon dioxide and Porcelain cement   ,After sintering under high temperature and high voltage , the resistor core was build ,then take the insulation coating.

  Ⅱ Saver than the wire-wound resistor and film resistor , which will avoid the wire disconnecting and the film breaking up .

  Ⅲ High peak power can be reached at 5KW-30KW in short time.
  Ⅳ Good performance in bearing high voltage and high current.
  Ⅴ Products meet the RoHS requirments.

㈢Applications:

 Ⅰ Radar,Motor Drives, Broadcast Transmitters.
 Ⅱ X-Ray equipment ,Lasers,Medical Defibrillators.
 Ⅲ Dynamic Braking, Soft-start/Current-limit equipment.
 Ⅳ Snubber Circuits, Dummy Loads, Energy Research field..
 Ⅴ RF Amplifiers,Semiconductor Process,Power Conditioning.
