1537R-70F

Overview

The Delevan 1537R-70F is a fixed through-hole RF inductor with an inductance of 75 µH and a tolerance of ±1%. It features a molded unshielded construction with an iron core. The component has a maximum DC resistance of 3.7 Ohms and a rated current of 166 mA. Dimensions are 3.96 mm diameter by 9.53 mm length. It operates within a temperature range of -55°C to 105°C.

Feature Summary

Molded unshielded coil design for RF applications
Axial lead termination for through-hole mounting
Iron core construction

Applications

RF circuit filtering
Signal processing networks
Impedance matching circuits

Procurement Notes

Verify the specific suffix 'R' indicates RoHS compliance status against manufacturer documentation, as legacy MIL-PRF-39010 variants may differ. Confirm axial lead availability and package integrity upon receipt. Ensure storage conditions maintain component reliability within the specified temperature range.

Selection Notes

Select this component for high-inductance RF applications requiring unshielded performance. Compare the 3.7 Ohm DCR and 166 mA rating against circuit requirements. Consider the physical dimensions for board space constraints relative to shielded alternatives.

Part Context

This part belongs to the API Delevan 1537 series of fixed inductors. These components are designed for general-purpose RF use. The series offers various inductance values with consistent physical footprints. They adhere to military-grade quality standards where applicable.

Replacement Considerations

Direct substitutes include ER1537-70JR (75 µH, 147 mA) and 1537-70F (75 µH, 166 mA). Verify current ratings and tolerance differences when substituting.
