PBF-1201-22

Overview

The PBF-1201-22 is a single-phase power line filter module designed for equipment requiring compliance with EMI regulations such as VCCI, CISPR, FCC, and VDE. It attenuates conductive emissions from power supplies while maintaining a compact package. The component features a rated voltage of 250V (AC/DC) and a rated current of 1A. Electrical specifications include a test voltage of 2500V AC for one minute between terminals and case, with a minimum isolation resistance of 100MΩ at 500V DC. Leakage current is limited to 0.35mA max at 250V, 60Hz, and the DC resistance is 1.2Ω max. The operating temperature range is -25°C to +85°C.

Feature Summary

• Designed to conform to international EMI regulations including VCCI, CISPR, FCC, and VDE standards.
• Attenuates conductive emissions generated by power supplies to ensure signal integrity.
• Features a compact package suitable for space-constrained applications.
• Allows for simple wiring and easy maintenance through fast-on tab connections.

Applications

• Equipment designed to conform to EMI regulations
• Power supply noise suppression
• General-purpose noise suppression in low-current DC and AC power systems

Procurement Notes

Verify the specific datasheet version and safety certifications (UL1283, CSA Std. C22.2 No. 8, VDE0565 Teil 3) applicable to your region and end-product requirements. Confirm that the 1A rated current and 250V rating align with your system's electrical loads. Ensure compatibility with fast-on tab mounting methods during mechanical integration.

Selection Notes

Select this model for applications requiring single-phase filtering with a 1A current capacity. Compare against the PBF-1202-22 if higher current handling is needed. Consider the leakage current specification of 0.35mA for sensitive medical or safety-critical designs. Verify thermal management capabilities within the -25°C to +85°C operating range.

Part Context

The PBF-1201-22 belongs to the PBF series of power line filter modules manufactured by TDK-Lambda. This series includes variants like the PBF-1202-22, PBF-1203-22, and PBF-1206-22, which offer different current ratings. These components are part of TDK-Lambda's broader portfolio of AC-DC power solutions and EMI suppression devices.

Replacement Considerations

The PBF-1202-22 serves as a direct substitute within the same series for applications requiring 2A rated current instead of 1A. Other models in the PBF series may be considered based on specific current and voltage requirements, ensuring identical mounting and functional characteristics.
