Fixed Inductors Applications

• RF oscillation circuits
• IF choke applications
• Power Amplifier (PA) circuits requiring large currents
• Low Noise Amplifier (LNA) circuits

Fixed Inductors Procurement Notes

Verify the specific suffix codes against official Viking Tech documentation to ensure correct tolerance and packaging specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering. Ensure the selected variant matches the required inductance value and current rating for the target application circuit.

Fixed Inductors Selection Notes

Select this component for high-frequency RF applications where high self-resonant frequency is critical due to its wirewound ceramic construction. Consider the 680 mA rated current and 104 mΩ DC resistance when designing power stages. The unshielded nature requires careful layout consideration regarding magnetic interference compared to shielded alternatives.

Fixed Inductors Part Context

This part belongs to the Viking Tech WL Series of wirewound chip inductors. The series utilizes ceramic bodies and wirewound technology to achieve superior performance in terms of self-resonant frequency and current handling. These components are specifically engineered for general-purpose and RF applications requiring compact surface-mount solutions.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 7.5 nH inductance, 0402 package size, and similar current ratings. Verify that alternative components maintain comparable self-resonant frequency characteristics and DC resistance values to ensure circuit performance integrity without redesigning the PCB layout.
