ER1641-123JP

Fixed Inductors Overview

The ER1641-123JP is a fixed axial leaded inductor from the Delevan ER1641 series, designed for military and high-reliability applications. It features a shielded molded construction with an iron core, offering an inductance of 12 µH ±5%. The component supports a maximum DC current of 200 mA and has a maximum DC resistance of 2 Ohms. Key electrical parameters include a Q factor of 50 at 2.5 MHz and a self-resonant frequency of 44 MHz. It operates within a temperature range of -55°C to 105°C.

Fixed Inductors Feature Summary

• Shielded molded construction minimizes electromagnetic interference
• Compliant with MIL-PRF-39010/02 military specifications
• Wide operating temperature range suitable for harsh environments

Fixed Inductors Applications

• Military electronic systems requiring MIL-PRF-39010 compliance
• High-reliability RF filtering circuits
• Aerospace power supply filtering applications

Fixed Inductors Procurement Notes

Verify that the specific order matches the ER1641-123JP designation, as suffixes may indicate variations in tolerance or packaging. Confirm RoHS non-compliance status if environmental regulations apply to the final assembly. Ensure procurement channels provide valid traceability documentation required for military-grade components.

Fixed Inductors Selection Notes

Select this component when a shielded 12 µH inductor with 200 mA rating is required for through-hole mounting. Consider the 44 MHz self-resonant frequency limit for high-frequency circuit designs. Compare against unshielded alternatives like the ER1641-512JS if magnetic coupling mitigation is not a primary design constraint.

Fixed Inductors Part Context

This part belongs to the ER1641 series, which adheres to the MIL-PRF-39010/02 standard for fixed inductors. The series utilizes iron cores and offers various inductance values in an axial package. It is distinct from the 1641 series, which typically uses ferrite cores and different shielding configurations.

Fixed Inductors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-reference with other MIL-PRF-39010/02 compliant inductors only if exact parameter matching is verified through official manufacturer datasheets.
