Thunder Precision Resistor Co., Ltd. disclosed the process and preparation methods of making a new kind of UHF RF resistors: (1) Take a certain mass of nano silicon carbide with a particle size of 20nm ~ 50nm and disperse it in 95% ethanol with a mass multiple of 5 ~ 8 times, and then add nano alumina with a particle size of 20nm ~ 50nm with a mass of 2 ~ 3 times of nano silicon carbide to fully disperse it; (2) Add silane coupling agent dl602 with 2% ~ 3% mass of nano silicon carbide, fully stir until the system thickens, and then add organic Polyborosilazane iota-9120 with 0.3 ~ 0.5 times mass of nano silicon carbide to fully disperse; (3) in air atmosphere, the mixture of step 2 (step 2) was desiccant and cured by spray drying method, and the modified filler was prepared.

RN series high stable metal film resistors with stability established Thunder Precision Resistor Co., Ltd. makes RN series resistors that meet requirements of MIL-R-55182 with established reliability. The hard Bakelite mold construction provides superior moisture protection RN series high stability resistors are made of 96% alumina ceramic cores sputtering with high grade professional metal film trimmed with the professional laser machines to achieve uniform helix grooves without hurt the ceramic cores. The production procedure is introduced from Europe in 1989. All materials of to make RN series high stability resistors have been keep the same as they are introduced to guaranty the high quality and high stability as well.

There are many different types of Resistor available which can be used in both electrical and electronic circuits to control the flow of current or to produce a voltage drop in many different ways. But in order to do this the actual resistor needs to have some form of “resistive” or “resistance” value. Resistors are available in a range of different resistance values from fractions of an Ohm ( Ω ) to millions of Ohms.

Thunder Precision Resistors has more than 29 years of experience in developing, designing and manufacturing qualified high precision resistors. All productions are strictly controlled and follows an extensive set of instructions established in production procedure for reproducibility which was introduced from Europe. The quality of the products is always the first priority of Thunder Precision Resistors that is also our company quality policy. BSI issued ISO9000 Quality Management Certificate to Thunder Precision Resistors in 1998 and upgraded it in June 2016 to ISO9001:2015.
