Overview
The Delevan 1537R-82J is a fixed, unshielded molded RF inductor with an inductance of 130 µH and a tolerance of ±5%. It features a maximum DC current rating of 121 mA and a maximum DC resistance of 5.45 Ohms. The component operates within a temperature range of -55°C to 105°C and exhibits a Q value of 65 at 790 kHz. Its self-resonant frequency is 8.5 MHz. The axial leaded package measures 3.96 mm in diameter by 9.53 mm in length.
Feature Summary
- Molded construction using iron core material for stable RF performance
- Established reliability design compliant with MIL-PRF-39010 standards
- Unshielded axial leaded configuration suitable for through-hole PCB mounting
Applications
- RF circuit filtering
- Impedance matching networks
- General-purpose RF signal processing
Procurement Notes
Verify RoHS compliance status as the ER1537 series is typically non-compliant. Confirm that the specific ordering suffix matches the required electrical parameters. Ensure the procurement channel provides valid traceability documentation for established reliability components. Check for any specific handling requirements due to the axial leaded form factor during assembly.
Selection Notes
Select this component when a high-inductance value is required for RF applications with moderate current constraints. The 130 µH value and 121 mA rating suit specific filter designs. Consider the axial package dimensions for board layout compatibility. Verify that the unshielded nature does not interfere with nearby sensitive circuitry.
Part Context
This part belongs to the Delevan ER1537 series, which consists of established reliability RF inductors. These components are designed for demanding environments and often adhere to military specifications. The series offers various inductance values while maintaining consistent physical dimensions and mounting styles for standardized integration.
Replacement Considerations
Direct substitutes include other parts from the Delevan ER1537 series with identical electrical characteristics. Cross-reference with MIL-PRF-39010 qualified equivalents if military-grade reliability is required. Ensure any replacement maintains the same axial lead spacing and overall envelope dimensions.
