ULRG252512R005F in WEC Shunt Resistors Family
The ULRG252512R005F sub-family, manufactured by Welwyn (TT Electronics), belongs to the WEC series of ultra-low ohmic metal element shunt resistors. Designed for precise current sensing, these components utilize a robust metal plate construction to ensure low inductance and high stability. They are engineered to handle continuous power ratings up to 2.5W within a compact 2512 footprint, making them essential for monitoring high-current paths in power management systems where thermal management and accuracy are critical design constraints.
Variants in This Sub-Family
Variants within this sub-family primarily differ in their lead-free status, packaging format (such as T&R quantities), and specific termination finishes. Some derivatives might feature specialized soldering pads or thermal management enhancements, such as the SLT suffix denoting long-term stability testing or specific material treatments. While the core 5 mOhm resistance and 2.5W power rating remain constant, engineers should verify the specific suffix for AEC-Q200 compliance levels.
