The 1538M02 is an EMI/RFI choke from the 1538 Series, providing 10 uH (+/-10%) with a maximum DC current of 9 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 1538M02 are a maximum DC resistance of 0.017 ohms and a self-resonant frequency of 21.6 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 10 uH in several current ratings. Alongside the 1538M02 at 9 A there are higher-current 10 uH versions (1538M09 at 12 A, 1538M16 at 16 A, 1538M22 at 20 A), so check the current your circuit will carry when selecting between them.
Physical size follows the series drawing dimensions: Dim. A 1.12 in (28 mm) maximum, Dim. B 0.63 in (16 mm) maximum, Dim. C 0.69 in (18 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 1538M02 is RoHS and REACH compliant, has a shipping weight of 0.05 lbs (0.02 kg), and is identified by UPC 623980299952 and UNSPSC 39121301.
Ideal For
