珐琅电阻（被釉线绕电阻）属于绕线电阻（型号RX20）的一种，将电阻系数较大的锰铜丝或镍铬合金丝绕在陶瓷管上，并将其外层涂以珐琅作为耐热的釉绝缘层加以保护。
Enamel resistance (glazed wire winding resistance) is a kind of winding resistance (model RX20). The manganese copper wire or nickel chromium alloy wire with larger resistance coefficient is wound on the ceramic tube, and the outer layer is coated with enamel as a heat-resistant glaze insulation layer to protect it.
珐琅电阻（被釉线绕电阻）的优势：
Advantages of enamel resistance (glazed wire wound resistance):
珐琅电阻（被釉线绕电阻）具有高稳定性，高精度，噪音低，大功率等特点。一般可承受1-500w的额定功率，可在150℃高温下正常工作，温度系数可做到小于10/℃，精度高于±0.01%。
Enamel resistance (glazed wire wound resistance) has the characteristics of high stability, high precision, low noise and high power. Generally, it can withstand the rated power of 1-500 w, and can work normally at 150 C. The temperature coefficient can be less than 10 /(?) C, and the accuracy is higher than (?) 0.01%.
绕线电阻的缺点是自身电感和分布电容比较大，体积大，阻值不高，不适合在2MHZ以上的高频电路中使用。只适合在要求大功率电阻的电路中做分压电阻或滤波电阻或高温工作场合。
The drawback of winding resistance is that its inductance and distributed capacitance are relatively large, its volume is large, and its resistance value is not high, so it is not suitable for high frequency circuits above 2MHZ. It is only suitable for dividing resistance or filter resistance or high temperature working occasion in circuit requiring high power resistance.
