Description and Introduction

TELECOMMUNICATIONS PRODUCTS The part T1108, manufactured by PULSE, is a common mode choke designed for EMI suppression in electronic circuits. Below are the specifications, descriptions, and features based on available factual data:

### **Specifications:**  
- **Manufacturer:** PULSE (part of YAGEO Group)  
- **Part Number:** T1108  
- **Type:** Common Mode Choke  
- **Inductance:** Typically ranges between 1mH to 10mH (exact value depends on variant)  
- **Current Rating:** Varies by model (commonly 0.5A to 2A)  
- **Impedance:** High impedance at noise frequencies (e.g., 100Ω @ 100MHz)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Voltage Rating:** Typically rated for 50V to 250V AC/DC  
- **Mounting Type:** Surface Mount (SMD) or Through-Hole (THT) depending on variant  

### **Descriptions:**  
- The T1108 is a passive electronic component used to suppress electromagnetic interference (EMI) in power and signal lines.  
- It filters out common-mode noise while allowing differential signals to pass through.  
- Commonly used in power supplies, data lines, and communication interfaces.  

### **Features:**  
- High common-mode noise attenuation  
- Compact and lightweight design  
- RoHS compliant  
- Reliable performance in harsh environments  
- Low DC resistance for minimal power loss  

For exact electrical characteristics, refer to the manufacturer’s datasheet for the specific T1108 variant.
