The TF2420VU-102Y6R0-01 is a common mode choke coil from the TF series, designed for AC power supply line filtering. It features a toroidal core and vertical through-hole mounting configuration without a terminal base. The component supports a maximum current of 6A with two lines. Its maximum DC resistance (DCR) is specified at 30 milliohms. The unit operates within a temperature range of -20°C to 120°C. Physical dimensions are 23.00mm in length, 20.00mm in width, and a maximum height of 26.00mm.
This component is officially listed as obsolete and no longer manufactured by TDK Corporation. Procurement should focus on verified replacement parts or authorized distributors holding remaining stock. Verify compatibility with existing designs before sourcing alternatives. Check datasheets for pinout and electrical equivalence when selecting substitutes.
Select this component for applications requiring robust common mode noise rejection in AC power lines. The 6A rating suits moderate power applications. Ensure the vertical form factor fits the mechanical constraints of the target enclosure. Consider the operating temperature range for environmental suitability. Verify that the low DCR meets efficiency requirements for the specific circuit design.
Part of the TF series of common mode chokes from TDK Corporation. This series includes various ratings for different current and impedance needs. The TF2420VU variant specifically denotes a vertical type without a terminal base, distinguishing it from other mounting options in the lineup.
