CRCW040247R0FKED is a low-value, fixed SMD resistor (current-sense/shunt) in the CRCW family, from Vishay. It is an 0402 package device used for measuring current with minimal voltage drop.
Key points:
- Value: 0.047 Ω (47 milliohms).
- Tolerance: F = ±1%.
- Temperature coefficient: K ≈ 100 ppm/°C.
- End code “ED” indicates RoHS/compliant, lead-free packaging.
- Typical use: current sensing in power supplies, DC-DC converters, motor drivers, and other power-management circuits.
- Power rating: around the 0402 class (roughly 1/16 W); consult the datasheet for exact max current and thermal limits.
Note: Always verify exact specs in the manufacturer datasheet for the specific lot.

Equivalents are any 0402 (1005) 47 Ω chip resistor with the same tolerance/power rating (e.g. 47 Ω ±1%, ~1/16 W). Common cross-reference series:
