Primeworld TXL26--- range of high current inductors is designed to operate in high frequency switching regulator circuits. Windings are “Class 155” (IEC 60317-0-1) or higher temperature enamelled copper wire terminated using SnCu solder on to two of the diagonally opposite tin plated pins of a vertical EF25 bobbin. Bobbin material is Phenolic PM8375 of Sumitomo (Sumidurez) with a flammability rating of UL94 V-0 @ 0.49mm that also withstands assembly process temperatures of up to 260 deg C.
High frequency low loss ferrite cores used in TXL26 series make them a superior choice for high frequency switching regulators. TXL26 range not only offers lower core losses but also low ripple current by keeping inductance virtually constant over the load range. Vertical mounting configuration and its narrow width allow TXL26 range to directly replace toroidal inductors using iron powder and other expensive alloy materials.
