NOTES:
- Test Frequency : 100KHz / 0.1Vdc
- Testing Instrument : L:HP4284A, CH11025,CH3302, CH1320, CH1320S LCR METER/Rdc:CH16502, Agilent33420A MICRO OHMMETER.
- Heat Rated Current (Irms) will cause the coil temperature rise approximately,△T=40℃ without core loss.
- Saturation Current (Isat) will cause L0 to drop approximately 10%
- The part temperature (ambient + temp rise) should not exceed 125℃ under worst case operating conditions. Circuit design, component, PCB trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application.
- Operating Temperature: -40℃ - +105℃.
- Storage Temperature: -40℃ - +105℃.
Note: Product specifications can be customized.
FAQ
Q: How to apply for samples? What is the lead time?
A: You can submit a sample application through our website or email. Samples are free of charge and will be shipped within 3-5 working days. Mass order lead time is generally 2-8 weeks; custom products will be confirmed separately.
Q: Do you support small trial orders?
A: Yes. Small trial orders (below the standard MOQ) can be negotiated and receive the same quality standards and delivery commitments as mass orders. Please contact our sales team for details.
Q: What is the significance of the shielded core and composite structure for applications?
A: The shielded core reduces electromagnetic interference, while the composite structure provides ultra-low audible noise. The high transient current handling capability prevents saturation, making it suitable for high-current POL converters and low-profile high-current power supplies. It is suitable for applications such as PDAs, laptops, and servers.
