1025R-80F

Fixed Inductors Overview

The Delevan 1025R-80F is a fixed, unshielded molded RF inductor designed for through-hole mounting. It features an axial leaded package with dimensions of 0.095 inches in diameter and 0.250 inches in length (2.41mm x 6.35mm). The component provides an inductance of 330 µH with a tight tolerance of ±1%. It supports a maximum DC current of 45 mA and has a maximum DC resistance of 28 ohms. The self-resonant frequency is specified at 4 MHz, and it operates within a temperature range of -55°C to +105°C.

Fixed Inductors Feature Summary

• Molded construction with iron core for stable RF performance
• Unshielded design suitable for general circuit layouts
• Axial leads for standard PCB insertion

Fixed Inductors Applications

• RF signal processing circuits
• Impedance matching networks
• Filter applications in radio frequency systems

Fixed Inductors Procurement Notes

Verify the specific suffix requirements against the manufacturer's official documentation to ensure correct tolerance and packaging specifications. Confirm RoHS compliance status and environmental certifications prior to integration. Cross-reference the part number with authorized distributors to validate authenticity and availability. Ensure that the thermal operating limits align with the final assembly environment.

Fixed Inductors Selection Notes

Select this component when a high-inductance value with low self-resonant frequency is required for RF applications. The 330 µH value and 4 MHz SRF make it distinct from lower-inductance variants in the 1025R series. Consider the 45 mA current rating and 28 ohm DCR for power handling constraints. The axial form factor requires adequate board spacing compared to surface-mount alternatives.

Fixed Inductors Part Context

This part belongs to the Delevan 1025R series of fixed RF inductors. The series offers various inductance values ranging from nanohenries to hundreds of microhenries. All members share similar physical dimensions and mounting styles but differ significantly in electrical parameters such as Q-factor, current rating, and self-resonant frequency based on the specific model number.

Fixed Inductors Replacement Considerations

Direct substitutes include other 1025R series parts with identical 330 µH inductance and ±1% tolerance. Verify that any alternative maintains the same 28 ohm DCR and 45 mA current rating to ensure circuit compatibility.
