In the modern electronics industry, the stability and reliability of the resistor is very important to the overall performance of the circuit, especially in some special working environments, such as high temperature, high humidity, strong corrosion and other harsh conditions, ordinary resistors are often difficult to meet the requirements of long-term stable work, you need another kind of resistance, anti-vulcanization chip resistor, such as ROHM SFR series. Designed for these special application scenarios.
ROHM SFR series resistors using thick film technology manufacturing, has excellent vulcanization resistance, special internal structure design, in the high temperature and high humidity sulfur-containing environment, still can maintain the stability and reliability of the resistance value, for some in the petroleum, chemical, mining and other industries used in the electronic equipment, is a revolutionary progress. Because the working environment of these industries is often accompanied by the presence of sulfides, ordinary resistors are prone to performance degradation or even failure under such conditions.
The ROHM SFR series resistors range in size from 1005 to 3225, with rated power ranging from 0.063W to 0.5W, and resistance values ranging from 1Ω to 10MΩ, meeting the diverse needs of different electronic devices for resistors, whether in precision measuring instruments or in high-power industrial control systems. SFR series resistors can find the right application space.
ROHM SFR series resistors also have excellent performance such as low noise and low temperature coefficient, and can also be used in a wide range of applications where circuit noise and temperature stability are required, such as communication equipment and medical equipment. In addition, the SFR series resistor models are diverse, including SFR01MZPF, SFR01MZPJ, SFR03EZPF and other specifications, these different types of resistors have differences in electrical performance, can be selected according to the specific circuit design requirements, so as to achieve the best circuit performance and cost effectiveness.
