Description and Introduction

Multilayer Chip Inductors The LL2012-F39NJ is a common mode choke designed for noise suppression in electronic circuits. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Inductance:** 20 µH (typical)  
- **Current Rating:** 3 A (max)  
- **DC Resistance:** 0.05 Ω (max)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Voltage Rating:** 50 V (DC)  
- **Frequency Range:** Up to 100 MHz  

### **Description:**  
The LL2012-F39NJ is a surface-mount (SMD) common mode choke used to suppress electromagnetic interference (EMI) in power lines and signal lines. It is part of the LL series, designed for high-performance noise filtering in compact applications.  

### **Features:**  
- **High Noise Suppression:** Effectively filters common mode noise.  
- **Compact Size:** Small form factor suitable for space-constrained designs.  
- **High Current Handling:** Supports up to 3 A, making it suitable for power lines.  
- **Wide Frequency Range:** Effective across a broad spectrum of noise frequencies.  
- **RoHS Compliant:** Meets environmental standards.  

This component is commonly used in power supplies, USB interfaces, and other circuits where EMI suppression is critical.
