Overview
The Delevan 1537R-60F is a fixed axial leaded RF inductor with a nominal inductance of 47 µH. It features an unshielded molded construction and a maximum DC resistance of 2.75 Ohms. The component supports a maximum DC current of 193 mA and operates with standard termination for PCB mounting. Physical dimensions include a length of 9.53 mm and a diameter of 3.96 mm. It belongs to the 1537/R series and is supplied in reel packaging.
Feature Summary
- Molded unshielded coil design for RF applications
- Axial leaded termination style for through-hole mounting
- Standard terminal configuration
Applications
- RF circuit filtering
- Impedance matching networks
- General purpose RF signal processing
Procurement Notes
Verify the specific manufacturer designation, as sources list both API Delevan Inc. and Delevan. Confirm RoHS compliance status varies across documentation. Ensure the ordering suffix matches the required tolerance and packaging quantity. Cross-reference the Mouser part number 807-1537R-60FTR for accurate identification during sourcing.
Selection Notes
Select this component for high-inductance RF applications requiring axial leads. The 47 µH value suits lower frequency RF bands compared to other series variants. Consider the 193 mA current rating for power handling limits. The unshielded design requires layout consideration for magnetic interference. Verify physical space constraints against the 9.53 mm length specification.
Part Context
This part belongs to the 1537/R series of RF inductors from Delevan. The series includes various inductance values ranging from microhenries to tens of microhenries. All members share identical physical dimensions and axial leaded form factors. The 1537R-60F represents a higher inductance option within this standardized family.
Replacement Considerations
Direct substitutes are not explicitly confirmed in public data. Other 1537 series parts like 1537-48F or 1537-56F offer different inductance values but share the same package. Verify electrical parameters before substitution.
