Overview
The Laird-Signal Integrity Products 28L0138-50R-10 is a single-line ferrite bead designed for axial through-hole mounting. It exhibits an impedance of 153 Ohms at 100 MHz and supports a maximum rated current of 5 Amperes. The component features a low DC resistance (DCR) of 10 milliohms maximum. Its physical dimensions include a diameter of 0.138 inches (3.51 mm) and a maximum height of 0.350 inches (8.90 mm). The device operates within a temperature range of -40°C to 125°C.
Feature Summary
- Provides high-frequency noise attenuation with specified impedance characteristics
- Supports high-current applications up to 5 Amperes
- Features low DC resistance for minimal power loss in the signal path
Applications
- EMI filtering in high-current power lines
- RF interference suppression in analog circuits
- Signal integrity enhancement in digital systems
Procurement Notes
Verify the specific impedance value of 153 Ohms at 100 MHz against design requirements, as this differs from similar series variants like the 28J or 28L-40 models. Confirm that the axial package dimensions fit the PCB layout constraints. Ensure the 5A current rating meets the operational load. Check RoHS3 compliance status if required by environmental regulations. Validate the manufacturer part number to avoid confusion with obsolete predecessors.
Selection Notes
Select this component when axial mounting is preferred over surface mount options for mechanical stability. Choose this model specifically for its 153 Ohm impedance profile, which distinguishes it from other 28L series beads with different impedance values. Ensure the application requires a 5A current handling capability. Consider the through-hole installation method for robust connections in industrial environments.
Part Context
This ferrite bead belongs to the 28L series from Laird-Signal Integrity Products, optimized for EMI suppression. It serves as a direct replacement for the discontinued 28J0138-11R-10. The component is manufactured under Laird Technologies' signal integrity division, focusing on passive filtering solutions for electronic systems requiring reliable noise reduction.
Replacement Considerations
The 28L0138-40R-10 is a confirmed substitute within the same series, offering 135 Ohms impedance at 100 MHz instead of 153 Ohms. Verify that the lower impedance value is acceptable for the specific circuit's noise filtering requirements before substitution.
