FAQ
Introduction Of Resistor Reference Material:
1.How to choose the resistor ?
1 We would like to commend the wirewound resistor for you when it will be used in low voltage(220v-3.5kv).
2 It is better to use glass glaze resistor in high voltage(above 5.0kv).
3 For high-frequency circuits,to recommend oxide film resistor or glass glaze resistors.The resistance of the structure body,determines that it has a low inductance.There are requirements on the circuit inductance,film resistor is your best choice.
2.Resistor structure model and parameters characteristics ?
2.1 Glass Glaze Resistor:It is extremely stable chemical properties resistor paste coated on 95%AL2O3 ceramic tube,high temperature resistance film formed after firing.In order to guarantee stable electrical performance parameters,the surface to be coated with a protective lacquer.Its characteristics:
Resistance Range:Ω--GΩ
Power Range:0.5--500W
Frequency Response:less oxide film resistor ideal,but much better than wire wound resistors.(Called non-inductive resistor)
2.2 Oxide Film Resistor:It is the liquid chemical reagent injected into the high pressure borrow about 800ºC 95%AL2O3 ceramic tube,in the high temperature generated in the resistive film.Surface without protective lacquer coating.Its characteristics:
Resistance Range:1Ω--5KΩ
Power Range:10W--500W
Frequency Response:≥100MHz Truly non-inductive resistor
2.3 Wire Wound Resistor:Alloy resistance wire is wound on an insulating substrate for the endurance temperature,the surface protective layer coating made of resistive components.Because the different of the coated and package,it can divided into paint type,glaze type,metal shell type,porcelain shell type.Its characteristics:
Resistance Range:0.15Ω--20KΩ
Power Range:1W--500W
Frequency Response:inability to completely eliminate inductive factors,the frequency characteristics of the worst of the three resistors
3.High voltage resistors abide by electronics basic formula yet Using in the equipment circuit ?
Ohm Law
V=IR
Here:
I-Flowed Resistor Current,Dimension:A.
V-Voltage Exerted Resistor,Dimension:V.
R-Resistor's Resistance,Dimension:Ω.
4. How to choose the resistor power?
Power is larger (≥ 20W) of the load resistor at full power for a long (more than 2 hours) work surface will produce 300ºC temperature of around. And safe use of the resistor surface temperature is preferably maintained at less than 200ºC. Therefore, when the choice of the resistor, reduced power in using should be considered.
5.Withstanding Voltage?
China National Standard GB/T5729-2003/IEC60115-1:2001 in on the withstand voltage so provides:"In addition to surface mount resistors for all except resistors,test voltage shall be applied to the following two electrodes between:two resistors connected together as a lead-out electrode,V-block,a metal foil or mounting member as the other electrode,test voltage is AC(40Hz-60Hz),the peak of about 100v/s rate of rose from zero detailed specification insulation voltage worth 1.42 times the specified voltage is reached after keeping 60s(±5s).
Obviously,this is the measurement resistor resistance of the insulation coating layer or carrier(such as porcelain) the withstand voltage performance.Therefore,the Withstanding Voltage are not necessarily linked with the resistor's other technical parameters,like power,resistance,etc.
6. Using note?
The resistor is a heating component. During use, please pay attention to whether the surface temperature rise have effect on other elements. Of course, when choosing resistor, we will provide all technology parameters of the product for you to ensure your using. Please use according to technology parameter!
7. Why ask the working voltage, resistance value, resistor tolerance, temperature coefficient, contour dimension, main use of the resistor for the buyers every time?
Our company offer products in multiple dimensions, types, uses. According to that data you providing, we will choose optimum resistor for you. The optimum resistor will bring to the good influence for your produce, reducing power consumption and extending use life.
