1330R-78J

Fixed Inductors Overview

The Delevan 1330R-78J is a fixed surface-mount RF inductor from the 1330/R series. It features an inductance of 270 µH with a maximum DC resistance of 25 Ohms and a rated current of 47 mA. The component utilizes an unshielded iron core design, suitable for radio frequency applications. It operates within a temperature range of -55°C to +105°C and is supplied in reel packaging.

Fixed Inductors Feature Summary

• Unshielded construction utilizing an iron core material
• Designed specifically for radio frequency (RF) choke applications
• Surface mount package configuration for PCB integration

Fixed Inductors Applications

• RF signal filtering
• Choke circuits in radio frequency systems
• General purpose RF inductive components

Fixed Inductors Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan and generic Delevan branding. Confirm RoHS compliance status directly with the supplier, as documentation varies between compliant and non-compliant records. Ensure the ordering quantity aligns with the standard reel packaging requirements specified by the manufacturer.

Fixed Inductors Selection Notes

Select this component when a 270 µH inductance value is required for RF circuitry. The high DC resistance of 25 Ohms and low current rating of 47 mA define its operational limits. Consider the unshielded nature of the device regarding potential electromagnetic interference in dense layouts compared to shielded alternatives.

Fixed Inductors Part Context

This part belongs to the 1330/R series of fixed inductors manufactured by Delevan. The series includes various inductance values tailored for SMD applications. Similar parts in the family include the 1330R-44K and P1330R-334H, which share the same physical footprint but differ significantly in electrical characteristics and core materials.

Fixed Inductors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 270 µH inductance, 47 mA current rating, and 25 Ohm DCR specifications against other unshielded RF inductor offerings.
