Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the official TDK/EPCOS datasheet to ensure correct tolerance and packaging specifications. Confirm that the requested variant matches the required inductance value and physical dimensions for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Ensure compliance with environmental regulations such as RoHS if applicable to your production requirements.

Fixed Inductors Selection Notes

Select this component when a low-profile SMD inductor with a ceramic core is required for RF applications. The 1210 package size offers a balance between current handling and board space efficiency. Consider the 700 MHz self-resonant frequency limit to ensure operation below the resonant point for effective inductive behavior. Evaluate the 0.6 Ω DC resistance against power loss constraints in the target circuit design.

Fixed Inductors Part Context

This component belongs to the B82422A*100 series of SMT inductors manufactured by EPCOS AG, now part of the TDK Group. The series is characterized by its use of ceramic cores and suitability for high-frequency applications. The specific model indicates an 82 nH inductance with K tolerance, housed in a standard 1210 case size commonly used in consumer electronics and industrial equipment.

Fixed Inductors Replacement Considerations

Consult the official TDK replacement guide for direct equivalents. Verify that any substitute maintains the same 1210 footprint, 82 nH nominal value, and similar self-resonant frequency characteristics to ensure circuit compatibility without redesign.
