产品介绍 Product Introduction

无感水泥电阻是水泥电阻的一种，是使用交叉绕制出来的电阻芯做出来一种特殊的水泥电阻，相较于有感水泥电阻，无感水泥电阻的感抗值较小，不易损坏回路。

Non inductive cement resistance is a type of cement resistance that uses cross wound resistance cores to create a special type of cement resistance.Compared to inductive cement resistance, non inductive cement resistance has a smaller inductance value and is less likely to damage the circuit.

电阻使用建议

电阻在使用电路中[敏感词]留1.5 倍的功率余量，如电路中电压100V，电流0.01A，计算功率：P=100*0.01=1W，这时候电阻不能使用1W的，计算1*1.5=1.5W，没有1.5W 的电阻故需用到2W 的电阻。

It is best to leave 1.5 times the power margin for resistors in circuits. For example, if the voltage in the circuit is 100V and the current is 0.01A, the

calculated power is P=100 * 0.01=1W. At this time, a resistor of 1W cannot be used, and 1 * 1.5=1.5W is calculated. If there is no 1.5W resistor, a

resistor of 2W is needed.
