The 1538M01 is an EMI/RFI choke from the 1538 Series, providing 5 uH (+/-10%) with a maximum DC current of 10 A. Built on a high saturation flux density ferrite rod, the series is described as ideal for filtering or energy storage inductors, for engineers specifying EMI/RFI chokes in power and signal designs.
Electrical ratings for the 1538M01 are a maximum DC resistance of 0.013 ohms and a self-resonant frequency of 32.4 MHz. Inductance is measured at 1 kHz with 0 A DC current, and the typical inductance change is less than 5% at twice rated current.
The 1538 series offers 5 uH in several current ratings. Alongside the 1538M01 at 10 A there are higher-current 5 uH versions (1538M08 at 14 A, 1538M15 at 19 A, 1538M21 at 23 A), so check the current your circuit will carry when selecting between them.
Physical size follows the series drawing dimensions: Dim. A 0.88 in (22 mm) maximum, Dim. B 0.63 in (16 mm) maximum, Dim. C 0.50 in (13 mm) typical and Dim. D 0.04 in (1 mm) typical. The 1 in long leads are tinned to within 1/8 in of the body.
The rated ambient temperature range is -60 C to +85 C. The 1538M01 is RoHS and REACH compliant, has a shipping weight of 0.05 lbs (0.02 kg), and is identified by UPC 623980299945 and UNSPSC 39121301.
Ideal For
