Precautions for Use
z 由于外装涂层具有阻燃性特征,因此对外部冲击比较弱,请注意操作。请进行最小限度的清洗。刚刚清洗好以后的涂层非常薄弱,在产品完全干
燥之前,请勿对涂层施加外力。产品干燥后,涂层将恢复原有强度,请注意在洗净后的20分钟内,勿对电阻器的涂层施加外力。特别注意,请勿
将PCB板堆放起来。
z 在使用交流电路时,由于绕线构造会产生电感因素和寄生电容,因此,有可能会发生振动等异常现象。在使用时请仔细考虑其他部件常数的离散
情况。
z Be careful to handle these resistors because outer coatings are comparatively weak to outer shock due to flameproof special coats. Please wash them to a
minimum. No external force is given to the coating films until they are well dried because the coating films become weaker right after washing. The original
strength will be returned after they are dried, so please pay attention not to apply any external force onto the coating film of resistors for 20 minutes after
drying. Especially no PC boards shall be piled up.
z In case of using them for an AC circuit, abnormal phenomena like oscillation etc. occasionally happen as they have an inductance or a parasitic capacitance
because of their wiring structures. Use them by taking the dispersion of constants of other components into the consideration.
