CTLQ2220CF-681M

Fixed Inductors Overview

The CTLQ2220CF-681M is a shielded surface-mount power inductor from Central Technologies, rated at 680 µH with a ±20% tolerance. It features a maximum DC resistance of 6.16 Ω and a saturation current of 0.27 A. Designed for operation between -55 °C and +125 °C, this component utilizes a ferrite core within a 2220 package footprint to provide electromagnetic interference shielding.

Fixed Inductors Feature Summary

• Shielded construction minimizes electromagnetic interference
• Suitable for high-temperature environments up to 125 °C
• Surface-mount design facilitates automated assembly

Fixed Inductors Applications

• DC-DC converter output filtering
• Power supply input stages
• General-purpose power circuitry

Fixed Inductors Procurement Notes

Verify the specific suffix 'F' indicates RoHS compliance status as per manufacturer documentation. Confirm that the 6.16 Ω DCR and 0.27 A current ratings align with your thermal management requirements. Ensure the 2220 package dimensions fit your PCB layout constraints before finalizing procurement.

Fixed Inductors Selection Notes

Select this component when a 680 µH value is required in a shielded SMD format. The 0.27 A rating defines the operational limit; ensure peak currents remain below this threshold. Compare against unshielded variants if space is critical, noting the trade-off in EMI performance.

Fixed Inductors Part Context

This part belongs to the CTLQ series of fixed inductors manufactured by Central Technologies. The series offers various inductance values within the 2220 package size, providing engineers with standardized options for power electronics applications requiring compact, shielded magnetic components.

Fixed Inductors Replacement Considerations

Direct substitutes include other 680 µH, 2220 package shielded power inductors from Central Technologies or competitors. Verify equivalent DCR, current ratings, and temperature coefficients before substitution.
