Overview
The TE Connectivity SBL4R051J is a robust 4W axial-lead current sense resistor designed for precise current monitoring in demanding applications. Its 51 mΩ resistance value and 5% tolerance offer a balance between sensitivity and power handling. A critical design consideration for high-power current sensing is managing thermal runaway; while the SBL4R051J boasts a wide operating temperature range of -55°C to +250°C, designers must ensure adequate PCB heatsinking to maintain its specified parameters and prevent premature component degradation under continuous high-current loads.
Key Features
- Resistance: 51 mΩ
