1537R-80G

Overview

The Delevan 1537R-80G is a fixed axial leaded inductor with a nominal inductance of 120 µH and a tolerance of ±2%. It features an unshielded molded construction using an iron core, suitable for through-hole mounting. The component has a maximum DC resistance of 5.2 Ohms and a rated current of 140 mA. It operates within a temperature range of -55°C to +105°C.

Feature Summary

• Molded unshielded design utilizing an iron core for stable performance
• Axial through-hole termination style for standard PCB integration
• Established reliability specifications for consistent electrical characteristics

Applications

• General-purpose electronic circuits requiring filtering
• RF applications needing fixed inductance
• Power supply circuitry components

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets were acquired by TDK Corporation. Confirm that the requested part number aligns with current production lines under the new ownership structure. Ensure compatibility with established reliability standards if required by the application. Cross-reference datasheets from authorized distributors to confirm availability and manufacturing origin details before finalizing procurement orders.

Selection Notes

Select this component when a 120 µH inductance value is required with a 140 mA current rating. The unshielded nature necessitates layout considerations to prevent magnetic interference with nearby sensitive components. The axial package requires sufficient board spacing for insertion. Verify that the operating temperature range up to 105°C meets the environmental requirements of the target system.

Part Context

The 1537R series represents a line of fixed inductors known for their molded construction and axial leads. This specific model falls within the general-purpose category, offering a balance of inductance and current handling. The series is widely recognized in industrial and consumer electronics for its durability and consistent performance across various frequency ranges.

Replacement Considerations

Consult official substitution guides or manufacturer cross-reference lists for verified equivalent part numbers. Generic replacements may differ in core material, Q-factor, or physical dimensions. Ensure any substitute maintains the same axial form factor and electrical ratings to guarantee mechanical and functional compatibility.
