Unique-Bargains EE10 4+4Pin Transformer Component 10 Sets 20 Halves 10 Bobbins
Set of 10 EE10 vertical ferrite cores with 4+4 pin bobbins for switch-mode power supplies and high-frequency transformers
- 10 complete EE10 sets with 20 ferrite halves and 10 bobbins
- Vertical 4+4 pin layout on 2.5 mm pitch for compact PCB designs
- PC40 ferrite cores sized 10.3 × 4.8 × 5.5 mm for high-frequency operation
- Bobbins measure 10 × 10 × 14.5 mm with 7 × 4 × 6 mm winding window
- Suited for switch-mode supplies, DC-DC converters, chargers and industrial automation
EE10 Transformer Kit for Switching Supplies
This kit provides ten EE10 vertical ferrite cores with matching 4+4 pin bobbins for building custom high-frequency transformers. It suits hobbyists, repair technicians and engineers prototyping switch-mode power supplies, DC-DC converters or filter inductors.
20 Halves and 10 Bobbins Ready to Wind
The package delivers twenty ferrite halves and ten bobbins so each transformer is complete without sourcing separate parts. Pin spacing of 2.5 mm and row spacing of 8 mm match standard PCB layouts for vertical mounting.
EE10 Core Limits Power and Frequency
The EE10 core size of 10.3 x 4.8 x 5.5 mm and winding window of 7 x 4 x 6 mm restrict the achievable power throughput and maximum flux density. Designs needing higher energy storage or lower loss at very high frequencies require a larger core geometry.

Questions about this item
How often will the PC40 ferrite halves need replacement in a switching power supply running continuously?
The PC40 ferrite material has no scheduled replacement interval; the halves only need swapping if they crack or show thermal degradation after extended high-frequency operation.
What is the first limit reached when the EE10 core runs at full load for hours?
The 7 × 4 × 6 mm winding frame saturates before the bobbin or halves overheat, capping maximum throughput in sustained high-frequency use.
How much heat does the 10.3 × 4.8 × 5.5 mm ferrite core generate when the transformer operates all day?
Core loss in the PC40 material stays low at typical switching frequencies, so the small EE10 core runs warm but rarely requires forced cooling in enclosed supplies.
