Hammond 1539M02 10uH 14A EMI/RFI Choke, Ferrite Bobbin Core

The 1539M02 is an EMI/RFI choke from the 1539 series, described by the manufacturer as a heavy duty RF hash choke. It is rated 10 uH +/- 10% with a maximum DC current of 14 A, making it a practical choice for electronics designers and OEM engineers building filtering circuits or energy storage inductors.

The 1539M02 packs 10 uH and 14 A into the compact 0.83 in by 0.91 in maximum outline, with a 0.008 ohm maximum DC resistance. Other 10 uH values on the 1539 specification sheet are 1539M11 (17 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 0.008 ohms and the minimum Fo is 11.4 MHz.

• Inductance: 10 uH +/- 10%
• Fo minimum: 11.4 MHz
• Maximum DC resistance: 0.008 ohms
• Maximum DC current: 14 A
• Maximum Dim. A: 0.83 in (21 mm); maximum Dim. B: 0.91 in (23 mm)
• Typical Dim. C: 0.60 in (15 mm); typical Dim. D: 0.07 in (2 mm)

Inductance for the 1539 series is measured at 1 kHz with 0 A DC current, and typical inductance change is less than 5% at twice rated current. The 1539M02 is RoHS and REACH compliant and has a shipping weight of 0.1 lbs (0.05 kg).
