RNC55H4752FS – TBC

The RNC55H4752FS is a precision metal film resistor characterized by a nominal resistance value of 47.5 kΩ with a tolerance of ±1%. This through-hole resistor conforms to established reliability (ER) specifications, indicated by the “N/R” designation, suggesting a failure rate level is not reported or applicable. Based on the “RNC55” prefix and “VISHAY” association, it is likely manufactured using a hermetically sealed construction, providing enhanced environmental protection and long-term stability. The resistor utilizes a thin film resistive element, enabling precise resistance control and low temperature coefficient of resistance (TCR). The “H” in the part number likely denotes a specific TCR value, typically ±50 ppm/°C, although the exact value requires confirmation from the manufacturer’s datasheet.
