The 1539M13 is an EMI/RFI choke from the 1539 series, described by the manufacturer as a heavy duty RF hash choke. It is rated 50 uH +/- 10% with a maximum DC current of 10 A, making it a practical choice for electronics designers and OEM engineers building filtering circuits or energy storage inductors.
The 1539M13 sits between the 1539M04 (6.6 A) and 1539M19 (14 A) as the 10 A choice among the 50 uH parts in the 1539 series.
The choke is built on a high saturation flux density ferrite bobbin core. It has 1 in long leads, tinned to within 1/8 in of the body. Maximum DC resistance is 0.017 ohms and the minimum Fo is 3.6 MHz.
