1537R-94G

Overview

The Delevan 1537R-94G is a fixed, unshielded molded RF inductor designed for through-hole mounting. It features an axial lead configuration with a nominal inductance of 240 µH and a tolerance of ±5%. The component has a maximum DC resistance of 7.8 Ohms and supports a maximum DC current of 115 mA. It utilizes a phenolic core material and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded molded construction for general RF applications
• Axial lead termination style for PCB mounting
• Established reliability design using phenolic core

Applications

• RF circuit filtering
• General purpose inductive components
• Through-hole PCB assembly

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets are often managed by other entities. Confirm that the axial lead form factor matches the target board layout requirements. Ensure the 115 mA current rating and 7.8 Ohm resistance meet the circuit's electrical constraints before finalizing the procurement order.

Selection Notes

Select this component when an unshielded, high-inductance axial inductor is required for RF or general-purpose circuits. The 240 µH value and 115 mA limit define its operational envelope. Consider the phenolic core characteristics and the -55°C to +125°C operating range against environmental conditions.
