precision resistors

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.

8.3.3.3 Visual inspection 3：Minimum end solder width of MELF resistors after reflow soldering minimum end 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 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. minimum end 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 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.
