The 1538M05 is an EMI/RFI choke from the 1538 Series, providing 100 uH (+/-10%) with a maximum DC current of 4.9 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 1538M05 are a maximum DC resistance of 0.061 ohms and a self-resonant frequency of 2.08 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 100 uH in several current ratings. Alongside the 1538M05 at 4.9 A there are higher-current 100 uH versions (1538M13 at 6.8 A, 1538M20 at 10 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 0.81 in (21 mm) maximum, Dim. C 0.94 in (24 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 1538M05 is RoHS and REACH compliant, has a shipping weight of 0.05 lbs (0.02 kg), and is identified by UPC 623980299983 and UNSPSC 39121301.
