5、 Selection and application suggestions
When using CRH2512F3R30E04S 2512 3.3R 1% 2W high-power resistor, it is recommended that engineers pay attention to the following points:
1. Power derating design: When the ambient temperature exceeds 70 ℃, it is recommended to use derating according to the principle of reducing power by 10% for every 10 ℃ increase, in order to extend the life of the resistor and ensure long-term stability.
2. Heat dissipation layout: During PCB design, sufficient heat dissipation space should be reserved around the resistor to avoid close contact with other heating elements. If necessary, heat dissipation pads can be designed or copper plated areas can be increased to enhance thermal conductivity.
3. Welding process: It is recommended to use reflow soldering process, with a peak temperature not exceeding 260 ℃ and a duration controlled within 10 seconds to avoid high temperature damage to the resistor. Although the multi-layer electrode structure improves welding reliability, standard welding specifications still need to be followed.
4. Current sampling application: 3.3 Ω low resistance with ± 1% accuracy, very suitable for current detection circuits in power management. Pay attention to the symmetry of the wiring during design to avoid introducing additional parasitic resistance that may affect sampling accuracy.
