Unleashing Power Efficiency: FERRTX SDRH Series Magnetically Shielded Inductors

Why SDRH Inductors? Core Technologies Explained

1. Magnetic Shielding: Silence the Noise

FERRTX’s proprietary shielded core architecture minimizes electromagnetic interference (EMI) by confining magnetic flux leakage. This reduces radiated noise by up to 30 dB compared to unshielded alternatives, critical for:

• EMI-sensitive systems: Medical devices, ADAS sensors.
• High-frequency circuits: DC-DC converters switching at 100 kHz–10 MHz.
  Embedded Link: Shielding Inductor

2. Ultra-Low DCR & High Current Handling

With DC resistance as low as 0.008Ω (e.g., SDRH104-1R3) and saturation currents up to 12A (SDRH12 series), these inductors minimize power loss and thermal stress. Key advantages:

• Energy efficiency: Reduce I²R losses by 15% in 48V server power supplies.
• Compact design: High current density enables smaller PCB footprints.
  Embedded Link: Power Inductor

3. Automotive-Grade Robustness

AEC-Q200 qualified variants withstand harsh environments, making them ideal for:

• EV powertrains: Battery management systems (BMS), onboard chargers (OBC).
• Infotainment: Noise-immune RF Inductors for GHz-range signal integrity.
  Test Data: 500+ thermal cycles (-40°C ↔ +125°C) with <2% inductance drift.

Real-World Applications: Where Performance Meets Innovation

▶ DC-DC Converters: Efficiency Unleashed

In buck/boost topologies, SDRH inductors enable >95% efficiency at 2MHz switching frequencies. For example:

• SDRH1209-1R0Y: 1.0µH, 11A Irms, ideal for POL modules in NVIDIA GPU boards.
• SDRH10145-3R3: 3.3µH, 3.7A, used in 48V-12V automotive DC-DC converters.

▶ EMI Filtering: Tame the Noise Monster

Pair with EMI Filters to achieve EN55022 Class B compliance:

• Common-mode noise suppression: 30 dB reduction using coupled inductors in 3L buck-boost converters.
• Design Tip: Use SDRH7045 (3.3µH, 2.2A) with X/Y capacitors for <3mV PARD output ripple.
  Embedded Link: EMI Filter

▶ Automotive & RF Systems: Signal Perfection

• ADAS radar: SDRH’s low DCR (<20mΩ) ensures stable power for LiDAR Sensor arrays.
• 5G base stations: RF Inductors like SDRH0603-3R5 (3.5µH, 3.0A) enable impedance matching in mmWave PA modules.
  Embedded Link: RF Inductor, Sensor

Technical Specifications at a Glance

Pro Tip: For automated assembly lines, specify "Flat-top" models (e.g., SDRH0704) for pick-and-place compatibility. Tape-and-reel packaging available.

The FERRTX Advantage: Beyond Specifications
