Primeworld TXL16--- 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, wound on a vertical EF16 bobbin. One version of the bobbin with no pins and no stand-offs simply holds the SnCu tinned lead-outs in place, the other with four pins, terminates them on to two of the diagonally opposite tin plated pins using SnCu solder . 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 TXL16 series make them a superior choice for high frequency switching regulators. TXL16 range not only offers lower core losses but also low ripple current by keeping inductance constant over the load range. Vertical mounting configuration and its narrow width allow TXL16 range to directly replace toroidal inductors using iron powder and other costly alloy materials.
The TXL16 range is designed for use in buck regulators, boost regulators, isolated power supplies and dc/dc converters operating up to 500KHz.
