ER1641-302JS

Fixed Inductors Overview

The Delevan ER1641-302JS is a fixed through-hole inductor from the ER1641 series, designed for established reliability applications. It features an iron core and operates within a temperature range of -55°C to 105°C. The component has an inductance of 3 µH with a ±5% tolerance. Key electrical parameters include a maximum DC resistance of 350 milliohms, a rated current of 840 mA, and a self-resonant frequency of 85 MHz. It utilizes an axial package with dimensions of 0.162 inches in diameter by 0.410 inches in length.

Fixed Inductors Feature Summary

• Constructed with an iron core material for stable magnetic performance
• Encapsulated in a molded axial package suitable for through-hole mounting
• Complies with MIL-PRF-39010/02 standards for military-grade reliability

Fixed Inductors Applications

• Military electronic systems requiring high reliability
• Aerospace circuitry with strict environmental constraints
• RF filtering and signal conditioning circuits

Fixed Inductors Procurement Notes

Verify that the specific order suffix matches the required tolerance and packaging configuration. Confirm compliance with MIL-PRF-39010/02 specifications if the application demands military-grade certification. Ensure the procurement channel provides valid traceability documentation for the established reliability variant. Check for any specific handling requirements related to the axial leaded format during assembly.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 3 µH is required for high-frequency applications up to 85 MHz. The 840 mA rated current supports moderate power levels while maintaining low DC resistance. The wide operating temperature range ensures functionality in harsh environments. Consider the axial form factor for manual or automated through-hole insertion processes where compact radial packages are unsuitable.

Fixed Inductors Part Context

This part belongs to the ER1641 series, which offers various inductance values and tolerances. The 'J' suffix typically denotes a ±5% tolerance, while 'S' indicates the established reliability variant compliant with military standards. This series is distinct from the 1641R series, which may feature different core materials or shielding configurations.

Fixed Inductors Replacement Considerations

ER1641-302JM is a similar variant within the same series, potentially differing in tolerance or specific reliability classification.
