TECHNICAL INFORMATION:
- Inductance of PE 20s1604 measured on Agilient/HP4284 between pins 7 & 11 at 100kHz, 0.1 Vrms.
- The IDC rated is either 85% of the IDC saturation or the IDC heating depending which is lower.
- The IDC saturation is the current which causes the inductance to drop by 15% of its nominal value.
- The IDC heating is the current which causes the temperature of the part to increase by approximately 45℃.
FAQ
Q: What are the advantages of planar transformers compared to traditional wire-wound transformers?
A: Planar transformers use a low-profile structure and PCB-style winding design. They offer ultra-low leakage inductance (<0.2%), high power density (5W-25kW per component), low EMI radiation, and excellent thermal management. The low-profile design also significantly reduces height, making it suitable for high-density mounting applications.
Q: What are the advantages of ultra-low leakage inductance (<0.2%)?
A: Ultra-low leakage inductance reduces voltage spikes on switching devices, lowers switching losses, and improves system efficiency. It also reduces electromagnetic interference (EMI) to surrounding circuits, simplifying EMI filter design.
Q: How long is the delivery time and what packaging methods are used?
A: The standard lead time is 2-8 weeks after order confirmation, depending on product specifications and order quantity. Products are securely packed with cartons, foam, pallets, wrapping film, and fixing straps to ensure safe international transportation.
