Hammond 1539M07 500uH 2A EMI/RFI Choke, Ferrite Bobbin Core

The 1539M07 is an EMI/RFI choke from the 1539 series, described by the manufacturer as a heavy duty RF hash choke. It is rated 500 uH +/- 10% with a maximum DC current of 2 A, making it a practical choice for electronics designers and OEM engineers building filtering circuits or energy storage inductors.

The 1539M07 provides 500 uH in the compact 0.83 in by 0.91 in outline, rated 2 A DC with a 1 MHz minimum Fo. Other 500 uH values on the 1539 specification sheet are 1539M16 (3.7 A), 1539M22 (5 A) and 1539M28 (6.5 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 0.378 ohms and the minimum Fo is 1 MHz.

• Inductance: 500 uH +/- 10%
• Fo minimum: 1 MHz
• Maximum DC resistance: 0.378 ohms
• Maximum DC current: 2 A
• Maximum Dim. A: 0.83 in (21 mm); maximum Dim. B: 0.91 in (23 mm)
• Typical Dim. C: 0.68 in (17 mm); typical Dim. D: 0.04 in (1 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 1539M07 is RoHS and REACH compliant and has a shipping weight of 0.1 lbs (0.05 kg).
