Precautions for Use
z 由于包装涂层是阻燃性特种涂料，对外部冲击比较弱，所以在使用上应注意。应在最小限度清洗。清洗后涂层膜会比较弱，因此，在充分干燥
前，不要在涂层膜上施加外力。由于要在干燥后才能恢复到原来强度，因此应注意，在清洗后约20分钟内，在电阻的涂层膜上不要施加外力。特
别不要进行基板的堆叠等。
z 高电阻值的产品，为防表面漏电，请不要直接用手接触。
z 附近有导电体时，有可能发生电晕和放电短路，因此，请与我们咨询。
z 请勿在高温、高湿度和粘附部位脏污等不良条件下或进行树脂成型时使用本电阻器，因为这可能引起电阻值发生改变。
z 小于RCR50 100kΩ的电阻膜层有所不同。因此，被湿度较大的环境和离子材料污染后，其性能可能下降。对于此类情况，请事先向我们公司咨询。
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 Do not touch the resistors with high-resistance value by hand to prevent surface-leakage current.
z Consult with us when there are electric conductors near to because it may cause corona and short-circuit by discharge.
z Please do not apply resistors under such bad conditions as high temperature, high humidity, and foul adhesion, or with resin molding, because it may cause the
change of resistance value.
z The resistance film of less than RCR50 100kΩ is different. Therefore, the characteristic might decrease when it is polluted by a remarkable moisture
environment and the ionic material so inquire of our company beforehand, please.
