Overview
The Laird-Signal Integrity Products 28L0138-70R is an axial ferrite bead designed for power and signal line filtering. It provides an impedance of 220 Ohms at 100 MHz with a maximum DC resistance of 10 mOhm. The component supports a rated current of 5A and operates within a temperature range of -40°C to 125°C. It features a single-line configuration in an axial package.
Feature Summary
- Provides high impedance attenuation for electromagnetic interference suppression
- Supports high continuous current handling capabilities
- Designed for axial through-hole mounting applications
Applications
- Power supply input filtering
- Signal line noise suppression
- Electromagnetic compatibility (EMC) circuits
Procurement Notes
Verify the specific suffix requirements, as the 28L0138-70R designation may correspond to obsolete or inactive status compared to variants like the 28L0138-70R-10. Confirm availability and lead times directly with authorized distributors, as stock levels fluctuate. Ensure the selected part matches the required impedance and current ratings for the target circuit design before finalizing procurement orders.
Selection Notes
Select this component when axial mounting is preferred over surface mount options for high-current applications. Compare the 220 Ohm impedance at 100 MHz against circuit requirements to ensure adequate noise attenuation. Verify that the 5A current rating exceeds the maximum expected load current to prevent saturation or excessive heating during operation.
Part Context
This component belongs to the 28L series of ferrite beads from Laird-Signal Integrity Products. The series offers various impedance values and current ratings in axial packages. This specific model targets applications requiring robust EMI filtering with high current capacity in a through-hole form factor.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer catalogs for alternative axial ferrite beads with matching 220 Ohm impedance and 5A current ratings.
