Product Description
Product Overview
This series of inductors features a magnetically shielded structure with a closed magnetic circuit, providing strong electromagnetic interference (EMI) resistance, ultra-low buzzing, and high-density mounting capabilities. Designed for small size and high current handling (up to 60A), these components maintain excellent temperature rise and saturation current characteristics in high-frequency and high-temperature environments. Constructed with low-loss alloy powder and low resistance, they offer robust structure and high precision. They operate across a wide frequency range, extending beyond 5MHz, and are halogen-free and environmentally friendly. Ideal for applications in PADs, laptops, desktops, servers, audio systems, networking, security, mobile phones, and smart home devices.

Test Condition Remarks:
- All test data is reference to 25 ambient.
- Test Condition: 1MHz, 1Vrms (for some series) / 100kHz, 1Vrms (for other series).
- Isat: DC current at which the inductance drops less than 30% from its value without current (Maximum Value); DC current at which the inductance drops 30% from its value without current (Typical Value).
- Irms: For Maximum Value, T40; for Typical Value, T is approximate 40.
