Overview
The TF2514VU-131Y7R0-01 is a single-phase EMI filter manufactured by TDK Corporation. It belongs to the TF series of common mode choke coils designed for AC power supply applications. The component utilizes a toroidal core type construction and is intended for through-hole mounting on printed circuit boards. Its primary function is the prevention of electromagnetic interference (EMI) and radio frequency interference (RFI) from power supply lines, ensuring compliance with EMC standards in sensitive electronic systems.
Feature Summary
- Provides effective suppression of electromagnetic interference (EMI) and radio frequency interference (RFI) on AC power lines
- Utilizes a toroidal core design for high-performance common mode noise reduction
- Engineered for through-hole mounting to ensure secure mechanical integration
Applications
- Prevention of electromagnetic interference in AC power supply lines
- Protection of measuring equipment from external noise
- Mitigation of radio frequency interference in system equipment
Procurement Notes
Verify the specific suffix codes against official TDK documentation to confirm exact electrical characteristics and safety certifications. Ensure the procurement source provides valid datasheets matching the TF2514VU-131Y7R0-01 designation. Cross-reference manufacturer part numbers to avoid confusion with similar variants in the TF series that may have different ratings or pin configurations.
Selection Notes
Select this component when designing circuits requiring robust common mode noise filtering for single-phase AC inputs. Consider the toroidal core architecture for its efficiency in handling specific interference profiles. Validate that the through-hole mounting style aligns with the target PCB layout and assembly requirements for the intended industrial or consumer application.
Part Context
This component is part of TDK's TF series, which encompasses common mode choke coils and line filters for AC power supplies. The series is widely used for preventing multifunctioning in measuring and system equipment caused by electromagnetic disturbances. TDK manufactures these components using ferrite materials, leveraging their expertise in magnetic electronics established since 1935.
Replacement Considerations
Official substitutes within the TF series include TF2514HU and TF2514VU-131Y7R0-01 variants with differing suffixes. Verify compatibility by comparing rated voltage, current, and inductance values in the official datasheet before substitution.
