Additional Details

The inductance value for TSL0808S-470K1R2-PF is typically around 47 uH (as indicated by '470'). The DC resistance (DCR) is an important parameter for common mode chokes, as it impacts signal attenuation; a lower DCR is generally preferred. The rated current specifies the maximum current the choke can handle without saturating or overheating. The operating temperature range is another important consideration for selecting the appropriate common mode choke for a given application. Care should be taken to review the datasheet for specific performance curves and derating information. The 'K' likely indicates a tolerance of 10%.
