Procurement Notes
Verify the specific manufacturer designation TOKO, Inc against distributor listings to ensure authenticity. Confirm that the suffix =P3 aligns with the required packaging or tape-and-reel specifications for your assembly line. Cross-reference the part number A814AY-391K with the exact electrical parameters provided in the official datasheet to prevent substitution errors during procurement.
Selection Notes
Select this component when a 390 µH inductance value is required for surface-mount technology. Ensure the design accommodates the specified 490 mA current limit and 1.09 Ohm resistance. Verify that the physical footprint matches the 11.50 mm x 9.70 mm x 5.00 mm dimensions within the PCB layout constraints.
Part Context
This part belongs to the A814AY series of fixed inductors intended for surface mounting. The series includes various inductance values such as 100 µH and 470 µH, sharing similar physical characteristics and terminal styles. It serves as a standard passive component for signal conditioning and energy storage in compact electronic assemblies.
Replacement Considerations
Equivalent parts include A814AY-470K and A814AY-680K from the same manufacturer family. These alternatives share the same surface-mount form factor but differ in inductance values. Verify compatibility with circuit requirements before substituting.
