The performance comparison between RLM25FEER005 and STE1206M1W0R005FS is as follows:
Resistance and accuracy: Both have a resistance of 5m Ω and an accuracy of ± 1%. In circuits that require precise resistance and precise control of current and voltage, stable and accurate resistance values can be provided to ensure that the circuit operates according to design requirements.
Temperature coefficient: The temperature coefficients of RLM25FEER005 and STE1206M1W0R005FS are both ± 50ppm/℃. Under different temperature environments, the rate of change of resistance with temperature is consistent, and the stability affected by temperature is comparable.
Power: RLM25FEER005 has a power of 2W, STE1206M1W0R005FS has a power of 1W.
Package size: RLM25FEER005 adopts 2512 package, with a size of 6.40x3.20mm; STE1206M1W0R005FS is a 1206 package with dimensions of 3.20x1.60mm.
Working temperature: The working temperature range of RLM25FEER005 is 55 ℃~+170 ℃, and the general working temperature range of STE1206M1W0R005FS is 55 ℃~+125 ℃. Here are the reasons for recommending two models:
RLM25FEER005 high-power application scenarios: In power circuits for automotive electronics, power conversion modules for industrial equipment, and other circuits that require handling high power, the 2W power of RLM25FEER005 can better withstand energy loss in the circuit and reduce the risk of faults caused by power overload. Wide temperature environment requirements: In high-temperature industrial furnace control circuits or low-temperature polar detection equipment circuits, its working temperature range of 55 ℃~+170 ℃ can ensure stable performance under extreme temperature conditions and ensure the normal operation of equipment.
Heat dissipation advantage: The 2512 package has a larger size and a relatively larger heat dissipation area. In high-power and high heat generating circuits, the heat dissipation effect is better, which helps to maintain the temperature stability of the resistor itself and surrounding circuit components, and improve the reliability of the circuit.
STE1206M1W0R005FS space constrained scenario: In small consumer electronics products such as smartphones and tablets that require extremely high space, the small size of the 1206 package can effectively save circuit board space, enabling the product to achieve smaller size and thinner design.
General power circuit: In circuits such as ordinary home routers, Bluetooth speakers, etc. that do not require high power and have a power of 1W, using STE1206M1W0R005FS can ensure the normal operation of the circuit while reducing costs and occupying space.
Cost sensitive projects: In some electronic product projects with strict cost control, smaller package sizes and relatively lower power specifications usually mean lower costs, which can effectively control product costs while meeting performance requirements.
