Fixed Inductors Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as variations such as cut tape or reel formats may exist within the same base part number. Ensure that the requested quantity aligns with the manufacturer's standard factory pack sizes to avoid unnecessary handling fees. Confirm RoHS compliance status through official documentation prior to final procurement decisions.

Fixed Inductors Selection Notes

Select this component when a 270 nH inductance value is required for commercial-grade RF applications. The 0402 footprint allows for dense PCB layouts where space is constrained. Consider the 80 mA current limit and 7 Ohm resistance when designing power-sensitive circuits. The unshielded nature requires careful layout planning to minimize electromagnetic interference with adjacent components.

Fixed Inductors Part Context

This part belongs to the MHQ-P series of fixed inductors manufactured by TDK Corporation. The series specializes in small-form-factor RF components utilizing multilayer technology. These inductors are engineered for high reliability in consumer electronics and general commercial equipment, offering consistent performance characteristics across the operating temperature range.

Fixed Inductors Replacement Considerations

Cross-reference with other 270 nH ±3% unshielded 0402 RF inductors from different manufacturers if supply constraints arise. Verify that substitute components match the 900 MHz self-resonant frequency and 80 mA current rating to maintain circuit functionality without modification.
