Z7E

Fixed Inductors Overview

The Ohmite Z7E is a leaded RF plate choke designed for radio frequency applications. It features an axial termination style and measures 152.4 mm in length with a diameter of 14.29 mm. The component provides an inductance of 84 uH with a tolerance of 10%. It supports a maximum DC current of 1 A and has a maximum DC resistance of 4.7 Ohms. The self-resonant frequency is specified at 13 MHz, tested at 1 kHz. This unshielded wirewound inductor is packaged in bulk and weighs approximately 73.036 g.

Fixed Inductors Feature Summary

• Wirewound construction optimized for RF plate choke functionality
• Axial leaded termination for standard PCB mounting
• Unshielded design suitable for specific RF circuit layouts

Fixed Inductors Applications

• Radio frequency signal processing circuits
• RF power supply filtering
• High-frequency choke applications in electronic equipment

Fixed Inductors Procurement Notes

Verify the exact physical dimensions and lead configuration against your PCB footprint requirements before ordering. Confirm that the 1 A current rating and 4.7 Ohm DCR meet your circuit's thermal and electrical constraints. Ensure the unshielded nature of the component does not interfere with nearby sensitive traces or components in your assembly design.

Fixed Inductors Selection Notes

Select this component when a high-inductance RF choke with axial leads is required. Consider the 13 MHz self-resonant frequency limit to ensure operation below this threshold. The 10% tolerance may require adjustment in precision tuning circuits. Evaluate the physical size constraints due to the 152.4 mm length.

Fixed Inductors Part Context

The Z7E belongs to Ohmite's series of fixed RF inductors. It is categorized as a plate choke, distinct from general-purpose power chokes. This model is part of the broader Ohmite inductor portfolio, focusing on specialized RF performance rather than generic power filtering.

Fixed Inductors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing designs if sourcing alternatives, as leaded RF chokes have specific mechanical and electrical characteristics.
