0603 3.48R resistor model recommendation

The following are recommended and analyzed models for the 0603 package 3.48 Ω resistor (in order of priority):
1. General scenario recommendation: ELR06FG3R48DES
Power: 2/5W (0.4W)
Temperature coefficient: 50ppm/℃
Features: Standard metal film resistor, sufficient power margin, suitable for conventional circuits such as signal conditioning and current detection.
2. Anti sulfurization demand scenario: EAM06FG3R48DES
Power: 2/5W (0.4W)
Temperature coefficient: 50ppm/℃
Features: Anti sulfide metal film resistor, suitable for high humidity or sulfur-containing environments (such as industrial control, automotive electronics).
3. Low power scenario: TRL060301F3R48P05Z
Power: 1/10W (0.1W)
Temperature coefficient: 50ppm/℃
Features: Ultra thin design, suitable for space limited or low-power applications (such as portable devices, high-density PCBs).
4. Cost sensitive scenario: ELR06FP3R48DES
Power: 1/5W (0.2W)
Temperature coefficient: 50ppm/℃
Features: High cost-effectiveness, suitable for consumer electronics products with low power requirements.
5. Loose temperature stability scenario: ELR06FX3R48EES
Power: 1/10W (0.1W)
Temperature coefficient: 100ppm/℃
Features: Lowest cost, only recommended for non critical circuits that are insensitive to temperature drift.
Selection suggestion:
Prioritize confirming the maximum power consumption of the circuit (P=I ² R) and select models with a power margin of ≥ 50%.
EAM series is preferred for anti sulfurization requirements, and 50ppm temperature coefficient models are preferred for precision measurement circuits.
Conventional consumer electronics can choose TRL or ELR-FP series to balance cost and performance.
