  • Thunder Precision Resistor Co., Ltd. applied RoHS and Reach Test to guarantee all materials used in the products as well as the packing materials meet the Restriction of Hazardous Substances and REACH/SVHC requests. Thunder Precision Resistor Co., Ltd. requested all the material suppliers to provide RoHS and REACH/SVHC test reports annually and applied the RoHS and REACH/SVHC tests our selves occasionally to make sure all materials are under control even the packing materials. Thunder Precision Resistor Co., Ltd. makes high precision resistors and special resistors, such as high power precision wire wound resistors up to 150W with temperature coefficient low than 15ppm, high resistance resistors up to 10G Ohm with temperature coefficient of resistance lower than 25ppm/℃, ultra-precision resistors with tolerance up to 0.005% and temperature coefficient lowen than 1ppm/℃, high resistance wire wound resistors with resistance up to 100k Ohm, etc.

  • Hackers intercepted Thunder Precision Resistor's users' emails and sent them to us after modifying the email website suffix. All the information we replied to these email was rejected but we didn't received the failure info. Hackers intercepted our replied email and then tampered with the bank information, sent these fake info to our users, resulting in the failure of users' payment for several times. Please pay attention to the mail address you replied to check it is the normal one or different from the normal one. Thunder Precision Resistors will pay attention to those email contain certain importance info such ad bank payment info and the contract info, etc.

  • 分级说明:本文件规定的要求反映了如下三个产品级别:晶圆电阻使用厂家可以根据自己产品的定位选择合格判据的级别 1级:是使用在普通类电子产品中的仪器仪表生产过程中的检验要求; 2级:是使用在有可靠性要求的仪器仪表产品、设备的生产制造过程中的检验要求; 3级:是使用在有较高可靠性要求的仪器仪表产品、设备的生产制造过程中的检验要求

  • Ceramic composition resistors are 100% non-inductance and chemically inert so they have high reliability to provide a solution for wide range of applications, such as high-voltage and high energy surges, circuit breakers, spark plugs, distributor points, or coil leads to limit spurious high frequency signals from being emitted or carried on transmission lines.

  • MELF type ceramic resistors HPCM series are high pulse load resistors that are the good choice of ignition resistors of motorcycle and automobile starting system.

  • minimum side solder width of melf resistors after reflow soldering in larger than 50% of the diameter of the resistors or larger than 50% of the width of the solder pad. the wider the solder width the better the solder strongth. The high the tin filtration the better the solder strength will be. the most important of the the requirement of getting wide solder width at the side of melf resistors is the sufficient amount of tin paste on the solder pads. there are information in our file provided the detailed date of the dimension of the pads and the thickness of the tin mesh for customers reference. the most important of the the requirement of getting wide solder width at the end of melf resistors is the sufficient amount of tin paste on the solder pads.

  • Thunder Precision Resistor Co., Ltd. had made the wetting balance tests to prove the perfect solder-ability of the precision melf resistors made by thunder precision resistors. The test was made by SGS and the result of the test declared the high quality of the precision melf resistors made by thunder precision resistors.

  • Fusible wire wound resistors FEATURES · Advanced alloy wire technology · Fusible less than 60 seconds when against 25 times power abnormal applied or according to customer’s request · Reliable in pulse / transient / abnormal surge applications · Non-inductance winding available upon request · Flame retardant coating
