1537R-92G

Overview

The Delevan 1537R-92G is a fixed axial leaded RF inductor designed for through-hole mounting. It features an unshielded molded construction with a nominal inductance of 220 µH and a tight tolerance of ±2%. The component exhibits a maximum DC resistance of 7.45 ohms and supports a maximum DC current of 117 mA. Key electrical characteristics include a minimum quality factor (Q) of 33 at the self-resonant frequency of 16 MHz. It operates reliably within a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded molded coil design suitable for general RF applications
• Axial leaded termination style for standard through-hole PCB mounting
• High stability with ±2% inductance tolerance
• Robust thermal performance across extended industrial temperature ranges

Applications

• RF filtering circuits
• Impedance matching networks
• General purpose inductive components
• Signal processing systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct tolerance and packaging specifications. Confirm that the axial lead length and overall physical dimensions align with the target printed circuit board layout constraints. Cross-reference the RoHS compliance status and REACH regulatory requirements with current project standards before finalizing procurement orders.

Selection Notes

Select this component when high precision is required due to its narrow ±2% inductance tolerance. The unshielded configuration necessitates careful placement to prevent magnetic coupling with adjacent sensitive traces or components. Ensure the operating current remains below the 117 mA limit to maintain thermal stability and prevent saturation effects during continuous operation.

Part Context

This part belongs to the 1537R series of fixed inductors manufactured by API Delevan. The series provides various inductance values tailored for radio frequency applications. The 1537R-92G specifically addresses needs for higher inductance values requiring precise control, distinguishing it from lower-inductance variants within the same product family.

Replacement Considerations

Direct substitutes must match the 220 µH value, 117 mA current rating, and 7.45 ohm DC resistance. Verify that alternative components offer comparable Q factors and self-resonant frequencies near 16 MHz to maintain circuit performance integrity.
