The 1539M17 is an EMI/RFI choke from the 1539 series, described by the manufacturer as a heavy duty RF hash choke. It is rated 1000 uH (1 mH) +/- 10% with a maximum DC current of 2.5 A, making it a practical choice for electronics designers and OEM engineers building filtering circuits or energy storage inductors.
The 1539M17 provides 1000 uH (1 mH) at 2.5 A on the 1.22 in by 1.11 in maximum outline, with 0.279 ohms maximum DC resistance. Other 1000 uH values on the 1539 specification sheet are 1539M08 (1.3 A), 1539M23 (3.5 A) and 1539M29 (4.4 A), so compare current rating and body size when choosing.
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 0.279 ohms and the minimum Fo is 0.58 MHz.
