Active405 in stock
Overview
The RT0805FRE0739KL is a high-precision thin film chip resistor from Yageo's RT series, offering a 39 kOhm resistance in a standard 0805 surface-mount package. It is designed for applications requiring high stability and reliability, featuring a narrow 1% tolerance and a low temperature coefficient of 50 ppm/C. With an operating temperature range of -55C to 155C, it is suitable for demanding environmental conditions.
Why Choose This Part
The thin film construction provides significantly better stability and lower noise compared to standard thick film resistors. Its 50 ppm/C temperature coefficient ensures that resistance remains consistent across the full -55C to 155C operating range, making it a dependable choice for precision electronics.
Applications
Precision Voltage Dividers
Used in feedback loops for power supplies and analog signal conditioning where ratio stability is critical.
Sensor Interfacing
Acts as a stable pull-up or series resistor for analog sensors to minimize measurement drift over temperature.
Industrial Control Systems
Provides reliable performance in PLC and automation hardware that operates in wide temperature ranges.
Medical Instrumentation
Ideal for low-noise signal paths in diagnostic equipment requiring long-term accuracy.
