Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official Cal-Chip Electronics documentation to confirm electrical characteristics and physical dimensions. Ensure that the procurement source provides valid traceability for the active component status. Cross-reference the RoHS compliance and lead-free status with the most recent datasheet revisions to meet regulatory requirements for the intended assembly process.

Fixed Inductors Selection Notes

Select this component when a compact 0603 footprint is required for low-inductance applications. The 220 nH value suits high-frequency filtering needs where space constraints are critical. Consider the 200 mA current rating and 1.9 Ohm resistance for power loss calculations. The wide operating temperature range supports deployment in demanding environmental conditions without derating concerns.

Fixed Inductors Part Context

This component belongs to the NL series of molded chip wirewound inductors from Cal-Chip Electronics. These devices are designed for automatic mounting processes, addressing trends toward higher part density in modern electronics. The series utilizes heat-proof resin encapsulation and metal terminal electrodes to enhance durability and dimensional accuracy compared to traditional winding types.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 0603 package, 220 nH inductance, and similar current ratings. Verify compatibility with existing PCB footprints and reflow soldering profiles. Ensure alternative components maintain equivalent Q-factor specifications at relevant frequencies to preserve circuit performance integrity.
