CTSLF1045TF-331M

Fixed Inductors Overview

The CTSLF1045TF-331M is a shielded power inductor from the CTSLF1045 series by Central Technologies. It features a fixed inductance of 330 µH with a ±20% tolerance. The component is designed for surface mount applications and operates within a temperature range of -20°C to +85°C. Key electrical specifications include a saturation current (Isat) of 470 mA and a DC resistance (DCR) of 1.03 Ω. The part number suffix 'T' indicates tape and reel packaging, while 'F' denotes RoHS compliance.

Fixed Inductors Feature Summary

• Shielded construction to minimize electromagnetic interference
• RoHS compliant manufacturing process
• Surface mount device (SMD) form factor

Fixed Inductors Applications

• Switching power supplies operating between 100 kHz and 1 MHz
• General purpose power filtering circuits
• DC-DC converter output stages

Fixed Inductors Procurement Notes

Verify that the specific order includes the 'F' suffix to ensure RoHS compliance status matches project requirements. Confirm the 'T' suffix corresponds to the required tape and reel packaging format rather than bulk or cut tape. Cross-reference the 330 µH inductance value against circuit design constraints to ensure compatibility with the specified 470 mA saturation current limit.

Fixed Inductors Selection Notes

Select this component when a high-inductance value of 330 µH is required for low-frequency switching applications up to 1 MHz. The choice is driven by the need for effective shielding in compact designs where electromagnetic interference must be controlled. Ensure the application current does not exceed the 470 mA saturation rating to maintain stable inductance performance.

Fixed Inductors Part Context

This part belongs to the CTSLF1045 series of shielded power inductors manufactured by Central Technologies. The series offers a wide range of inductance values from 2.2 µH to 1000 µH, all sharing similar physical dimensions and mounting characteristics. The '1045' designation refers to the case size, indicating a standardized footprint suitable for automated assembly processes in consumer and industrial electronics.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include CTSLF1045TF-221M (220 µH) and CTSLF1045TF-471M (470 µH). These parts share identical mechanical dimensions and pin configurations but differ in inductance and current ratings. Verify that the alternative inductance value meets the specific circuit requirements before substitution.
