Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm tolerance and packaging configuration. Ensure the requested part matches the exact 2220 footprint dimensions and terminal finish requirements for your PCB layout. Cross-reference the RoHS compliance status with current regulatory standards applicable to your region before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a shielded inductor is required to prevent magnetic coupling in dense layouts. The 85 mA current rating dictates suitability for low-power applications; verify that the operating current remains within limits to avoid saturation. The 15 Ohm DC resistance impacts efficiency; calculate power loss based on expected RMS current to ensure thermal performance meets system constraints.

Fixed Inductors Part Context

This part belongs to the CTHC2220F series of wire-wound chip inductors from Central Technologies. The series offers various inductance values within the 2220 package size. The '102' code denotes the 1000 µH value, while 'K' typically indicates a ±10% tolerance. This specific model represents a shielded variant designed for noise-sensitive environments compared to unshielded alternatives.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 2220 footprint, 1 mH inductance, 85 mA current rating, and shielded drum core type. Verify that alternative manufacturers provide equivalent DC resistance and saturation characteristics. Ensure the replacement part maintains RoHS compliance and identical terminal plating for reliable soldering.
