Fenghua thin film automotive resistance is also a type of high-precision thin film SMT resistance.
The Nanjing Sart alloy film precision resistor SMD series belongs to the metal foil process technology, also known as alloy resistors. It has product characteristics such as high current, low temperature drift, high reliability, and low inductance, and is widely used in current sampling circuits. Therefore, it is also known as current sampling resistors. Sate SMD series alloy film precision resistance products have a wide range of selectivity, volume range (0603~4320), resistance range (2m Ω~700m Ω), and power range (0.5W~5W). This article will provide a detailed introduction to the main product selection parameters and product characteristics of Sart alloy film precision resistors.
The main core parameters of precision resistors include volume, resistance, accuracy, power, temperature drift, voltage, and temperature, which are key parameters. Each parameter will have certain changes in different environments, so even the resistance of the same parameter will have different changes in different applications. We can provide examples of precision resistors below.
We all know that precision resistors are mainly high-precision thin film mount resistors. In fact, thick films can also be used for high-precision resistors, and they have higher voltage resistance than thin film precision resistors. Their temperature coefficient can also reach (± 50ppm/℃), which has higher product cost-effectiveness. This article provides a detailed introduction to the main selection parameters and characteristics of the high-precision thick film SMT resistors of the Yageo brand.
Yageo is one of the world's largest resistance brand manufacturers. Yageo's high-precision thin film chip resistors adopt advanced sputtering technology, providing high precision, high stability, narrow tolerance of ± 0.1%, and low TCR of ± 25ppm/℃. The minimum size is 0402, and the minimum TCR is ± 5ppm/℃. Guoju thin film precision resistors are divided into: ordinary thin film precision resistors, automotive standard thin film precision resistors, and precision resistance series such as anti vulcanization and high voltage resistance.
The CSR series of Viking metal film precision resistors is a type of SMT wire wound resistor, also known as wafer resistors, with two main volumes: 0204 (3.5 * 1.4) and 0207 (5.9 * 2.2). MELF metal film precision resistor, size 0204/0207. The precision tolerance is 0.1%, TC5/10/15/25/50/100ppm. MELF is a cylindrical, lead-free surface resistor with metal electrodes.
Thin film passivated NiCr precision resistor, Size from 0402 to 2512, Tight tolerance 0.1% Low TCR 15ppm-50 ppm, 1-1.5Mohm resistance range for critical environment designs. Now a day, More designs request high reliable precision resistors in Aircraft, Military or critical devices, sensitive in humidity, acid. NiCr resistor has its’ disadvantage that is lower capability to against humidity and acid. To overcome the disadvantage, the extra passivation on NiCr to withstand humidity and acid thin film resistor which can pass the very strict testing conditions. PR series, a replacement of TaN Resistor, very fast delivery and competitive cost.
The VIP series of high-power thin film precision resistors adopts a process with a larger bottom solder pad, achieving higher power. The 1206 volume power can reach up to 1W. The resistance range is 10 Ω~100K Ω, with good anti vulcanization performance, suitable for harsh environments. This article introduces the selection parameters and product characteristics of the Guangjie high-power thin film precision resistor ARP series.
