Fenghua thin film resistor is a high-precision, low-temperature drift resistor product launched by Fenghua High Tech (FH), widely used in fields that require high precision and stability of resistors. The following is a detailed introduction to Fenghua thin film resistors:
CHARACTERISTICS
High precision: Fenghua thin film resistors have extremely high resistance accuracy, usually reaching ± 0.05% or even higher, which can meet the strict requirements of precision electronic circuits for resistance values.
Low temperature drift: Its temperature coefficient (TCR) is very low, usually between ± 5ppm/℃ and ± 50ppm/℃, which means that the resistance value has very little effect on temperature changes and can ensure the stability of the circuit in different temperature environments.
Good stability: Using special passivation materials and advanced manufacturing processes, Fenghua thin film resistors have good moisture resistance, corrosion resistance, and high reliability, and can work stably for a long time in harsh environments.
Adapt to multiple welding processes: Fenghua thin film resistors are suitable for welding processes such as reflow soldering and wave soldering, facilitating automated production and improving production efficiency.
Environmental compliance: Compliant with RoHS directive requirements, halogen-free, and meets the environmental standards of modern electronic products.
2、 Product series
Fenghua thin film resistors include multiple series to meet the needs of different application scenarios. For example:
AT series: precision resistors for automobiles, meeting all requirements of AEC-Q200 automotive standards, with specifications covering the full range of sizes from 0402 to 2512, featuring low temperature coefficient and high precision, suitable for the automotive electronics field.
TH series: Universal thin film resistors, available in full size from 0201 to 2512, with extremely high precision (currently up to 0.05% precision in mass production) and good resistance to sulfurization, suitable for various fields such as instruments, medical devices, testing/measuring equipment, etc.
TM series: Leadless metal film resistors (wafer resistors) with excellent overall stability, high precision, and very low TCR, suitable for high-precision equipment such as communication, medical, testing, or measurement.
