Technical FAQ
Frequently Asked Questions.
U coil formers are winding bodies for U ferrite core transformer applications. They are especially suitable for power transformers, pulse transformers and high-voltage applications.
U standard coil formers cover U 10 to U 20 and use hidden continuous round pins. U 25 universal coil formers use open continuous round pins and are available with m-, h- or z-solder pin concepts.
h-solder pins are used for radial winding of thin wires and strands. z-solder pins support space-saving installation on the printed circuit board.
Standard U coil formers use glass-fibre reinforced PA66 p6g with RTI +125°C. U 25 universal coil formers use PA66 A RV250 natural with RTI +100°C.
SB-U clamping brackets are steel components used to connect U ferrite core halves. One clamping bracket is required per core set and coil former.
Depending on configuration, U coil formers support short-term soldering temperatures up to +350°C for up to 2 seconds.
