TPSF12C1DYYR

Overview

The TPSF12C1DYYR is a common-mode active EMI filter (AEF) from Texas Instruments designed for voltage-sense, current-inject applications. It operates within an input voltage range of 8 V to 16 V and supports frequencies between 150 kHz and 3 MHz. The device is housed in a 14-pin SOT-23-THIN package. It is functional safety-capable, with documentation available to aid system design.

Feature Summary

• Voltage-sense, current-inject active EMI filtering architecture
• Functional safety capability with supporting documentation

Applications

• Common-mode EMI suppression in power systems
• Active filtering for high-frequency noise reduction

Procurement Notes

Verify the specific operating supply voltage requirements against the application design, as sources indicate ranges such as 8 V to 16 V or 12 V nominal. Confirm the package type is 14-SOT-23-THIN. Ensure the selected variant matches the required frequency range of 150 kHz to 3 MHz. Check for functional safety documentation availability if required for the system design.

Selection Notes

Select this component for applications requiring active common-mode EMI filtering with voltage-sense and current-inject capabilities. Consider the 14-SOT-23-THIN package size for space-constrained designs. Verify that the operational voltage range aligns with the system's power supply specifications. Evaluate the need for functional safety certification before finalizing the selection.
