1537R-88J

Overview

The Delevan 1537R-88J is a fixed, molded, unshielded axial leaded RF inductor. It provides an inductance of 180 µH with a tolerance of ±5%. The component features a maximum DC resistance of 6.75 Ohms and a rated current of 123 mA. Designed for through-hole PCB mounting, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Molded construction for mechanical stability
• Unshielded design suitable for general RF applications
• Axial leads for standard through-hole integration

Applications

• RF circuit filtering
• General electronic noise suppression
• Signal processing components

Procurement Notes

Verify the manufacturer part number against official Delevan documentation to ensure authenticity. Confirm that the specific ordering suffix matches the required tolerance and packaging format. Check for RoHS compliance status as indicated in the datasheet, noting that some variants may not meet current environmental standards.

Selection Notes

Select this component when a high-inductance value is required in a compact axial package. Ensure the circuit current does not exceed the 123 mA rating to prevent saturation or overheating. Verify that the unshielded nature of the coil does not interfere with nearby sensitive components due to magnetic field exposure.

Part Context

This part belongs to the 1537R series of RF inductors manufactured by Delevan. The series offers various inductance values in a standardized molded axial form factor. These components are designed for reliability in radio frequency environments where stable inductance is critical.

Replacement Considerations

Direct substitutes include other 180 µH axial molded inductors from Delevan such as the ER1537-88JR if established reliability specifications are required. Verify physical dimensions and electrical parameters match before substitution.
