The ERL28 ferrite high-frequency flyback transformer is designed for switching power supply and DC-DC converter applications, with efficiency up to 95%. It offers high isolation strength, low-profile design, and lightweight advantages. The product uses an ERL28 ferrite core, offering strong anti-interference capability, low distributed capacitance, and low transmission attenuation. The structure is robust and reliable. Inductance is fine-tunable, suitable for high-density mounting and good shielding applications. Multiple core series are also available, including PQ, EI, EE, EF, ETD, EFD, and RM, with custom design support for customer requirements. It is widely used in switching power supplies, chargers, alarm systems, TV/CRT monitors, UPS, VCD/DVD players, audio/video equipment, OA equipment, inverters, fax switching systems, and wave carrier filters.

FAQ
Q: Which topologies does this product support?
A: This transformer supports half-bridge and full-bridge SMPS topologies. It is also suitable for flyback power supply designs. Inductance is fine-tunable, adapting to various power conversion requirements.
Q: Which core series are available for customisation?
A: Multiple core series are available for customisation, including PQ, EI, EE, EF, ERL, ETD, EFD, and RM. These cover applications from low-power signal transformers to high-power switching power supplies.
Q: What are the advantages of the low-profile design?
A: The low-profile design reduces transformer height, saves PCB vertical space, and is suitable for thin power supply designs and space-constrained applications, while also reducing weight.
Q: How to apply for samples? What is the lead time?
A: You can submit a sample application through our website or email. Please provide your company information and target specifications (including core type, power, and output voltage requirements). Custom sample lead time is generally 7-10 working days. Mass order lead time is generally 2-8 weeks.
