Technical Specifications

The NFM839R02C100R470T1M00 has an impedance of 100 Ohms at 100 MHz and 47 Ohms at a lower frequency. It features a rated current of typically 2A. The DC resistance (DCR) is typically very low to minimize signal attenuation. It operates over a temperature range of -55°C to +125°C.

The dimensions are very small, typical of SMD components (e.g., 3.2mm x 1.6mm x height), making it suitable for densely populated circuit boards. It utilizes a ferrite core material designed for optimal common mode noise suppression.

This component is RoHS compliant, meaning it adheres to environmental regulations regarding hazardous substances. The T1M00 at the end likely denotes specific packaging details for tape and reel, indicating suitability for automated assembly.
