Supply information: Supports tape/shear tape packaging, unit price ¥ 1.263/piece (starting from 1000 pieces).
 
 
4、 Precautions and exclusion models
1. Models with mismatched resistance values:
 
The actual resistance of Bourns CRM2512FXR120ELF is 0.12 Ω (120m Ω), which is not 120 Ω and does not meet the requirements.   
The resistance of Bourns CRM2512JW2R2ELF is 2.2 Ω, which is also not applicable.   
 
2. Low resistance alloy resistors:
Such as Viking LR series, SINLOON 2WLR2512, etc., the resistance range is concentrated in 0.5m Ω -100m Ω, suitable for current detection rather than 120 Ω scenarios.
