Description and Introduction

Inductors for Power Circuits Wound Ferrite SLFseries The part **SLF10145T-3R3N3R7-PF** is a power inductor manufactured by **TDK Corporation**. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Inductance:** 3.3 µH (microhenries)  
- **Tolerance:** ±30%  
- **DC Resistance (DCR):** 3.7 mΩ (milliohms)  
- **Current Rating (Isat):** 45 A (saturation current)  
- **Current Rating (Irms):** 45 A (RMS current)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Core Material:** Metal alloy  
- **Shielding:** Shielded  
- **Package Type:** Surface mount (SMD)  
- **Dimensions (L x W x H):** 10.1 mm x 10.1 mm x 4.5 mm  

### **Descriptions:**
- Designed for **high-current, high-efficiency power applications** such as DC-DC converters, voltage regulator modules (VRMs), and power supplies.  
- Features a **low DC resistance (DCR)** to minimize power loss.  
- **Shielded construction** reduces electromagnetic interference (EMI).  

### **Features:**
- **High saturation current (45 A)** for demanding power applications.  
- **Compact SMD design** for space-constrained PCB layouts.  
- **Stable performance** across a wide temperature range.  
- **RoHS compliant** and lead-free.  

This inductor is suitable for **automotive, industrial, and telecommunications applications** where high power efficiency and reliability are required.  

(Note: Always verify with the latest datasheet from TDK for updated specifications.)
