Create Free Business AccountThe 1538M09 is an EMI/RFI choke from the 1538 Series, providing 10 uH (+/-10%) with a maximum DC current of 12 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 1538M09 are a maximum DC resistance of 0.012 ohms and a self-resonant frequency of 21.7 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 1538M09 at 12 A there are higher-current 10 uH versions (1538M16 at 16 A, 1538M22 at 20 A) and lower-current 10 uH versions (1538M02 at 9 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 0.64 in (16 mm) maximum, Dim. C 1.00 in (25 mm) typical and Dim. D 0.05 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 1538M09 is RoHS and REACH compliant, has a shipping weight of 0.1 lbs (0.05 kg), and is identified by UPC 623980300030 and UNSPSC 39121301.
