◇HOW TO APPLY RESISTORS CORRECTLY

1.The characteristics of resistor have relations to Temperature, Moisture and Voltage.

2.The rating of resistor is specified on the basis of Temperature.

3.The power rating resistor is all specified with a Direct-Current (D.C)

continuous working voltage at commercial-line frequency.

4.The test regarding characteristics of resistor, is principally specified on the basis of moisture.

5.Maximum rated voltage and maximum overload voltage are limited for each style of resistor.

(1) Generally, Rated VoltageWhere, E=Volt, P=Watt, R=Ohm.

(2) Generally, Overload Voltage,Application time=5 Seconds.

Note: Max. rated and Max. overload voltage are specified in each specification. So, the voltage value is computed over than specified voltage value, the specified value should be applied to resistor.

6.In the complicated or high density circuit, it is recommended that the wattage or ohmic values of resistor should have a large redundancy from a view point of

reliability.

7.It is necessary that the handling or wiring of resistor to the circuit, be carefully

and please do not inflict any stress to resistor with over heating application.

8. To rise the reliability of resistor, it is better to prefer resistor with uniform quality than taking resistor to meet with severe specification.

9.To rise the stability of resistor, it is very important by taking resistor to meet with circuit conditions and it is also economical not to have unreasonable design from the point of pricing of resistor.

10.Generally, failure of resistor takes a concentrated trend in the impulse circuit with complicated pulse wave form or LC circuit generated high voltage with transient phenomena. Therefore, it is very important for designers to consider these conditions in the circuit design if the resistor is applied in these circuit.
