Description and Introduction

Inductors for Power Circuits The SLF7045T-4R7M2R0-PF is a power inductor manufactured by TDK. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Inductance (L):** 4.7 µH (±20%)  
- **DC Resistance (DCR):** 2.0 mΩ (max)  
- **Current Rating:**  
  - **Saturation Current (Isat):** 40 A (typical)  
  - **Thermal Current (Irms):** 40 A (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Core Material:** Metal alloy  
- **Shielding:** Shielded  
- **Package Size:** 7.0 mm × 7.0 mm × 4.5 mm  

### **Descriptions:**  
- Designed for high-current applications such as power supplies, DC-DC converters, and voltage regulator modules (VRMs).  
- Features a compact, shielded construction for reduced electromagnetic interference (EMI).  
- Suitable for automotive and industrial applications due to its robust design.  

### **Features:**  
- **High Current Handling:** Capable of handling up to 40 A saturation current.  
- **Low DCR:** Minimizes power loss and improves efficiency.  
- **Shielded Design:** Reduces magnetic interference with nearby components.  
- **Automotive-Grade:** Meets reliability standards for automotive applications.  

This information is based on TDK's official datasheet for the SLF7045T-4R7M2R0-PF power inductor.

Application Scenarios & Design Considerations

Inductors for Power Circuits

Alternative Part Number

  • CDRH74NP-4R7MC --: Similar 7x7 mm shielded power inductor with 4.7 uH value and comparable current rating, direct functional drop-in from a different series.
  • SRR7045-4R7M --: Same 7045 footprint and 4.7 uH inductance with shielded construction, widely available alternate source.
  • LQH66SN4R7M03L --: 4.7 uH shielded power inductor in a comparable 6.6x6.6 mm size, suitable substitute when board space allows slight footprint variation.
