Description and Introduction

T1/CEPT/ISDN-PRI TRANSFORMERS Dual Surface Mount, 1500 Vrms, Extended and Standard Temperature Range The part **T1144** is manufactured by **PULSE**. Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** PULSE  
- **Part Number:** T1144  
- **Type:** Common Mode Choke (CMC)  
- **Inductance:** Typically in the range of a few millihenries (mH), but exact value depends on the datasheet.  
- **Current Rating:** Varies by model (check datasheet for exact current handling).  
- **Voltage Rating:** Designed for low to moderate voltage applications (specific ratings depend on the datasheet).  
- **Operating Temperature:** Standard industrial range (e.g., -40°C to +125°C, but verify with datasheet).  
- **Mounting Type:** Through-hole or surface mount (SMD), depending on variant.  

### **Descriptions and Features:**
- **Function:** Used for EMI suppression by filtering common-mode noise in power and signal lines.  
- **Applications:** Power supplies, data lines, USB ports, and other circuits requiring noise suppression.  
- **Construction:** Ferrite core with bifilar or multi-winding design for balanced impedance.  
- **Compliance:** Typically meets industry standards like RoHS, REACH, and may have UL recognition (confirm with datasheet).  
- **Variants:** May come in different inductance values, current ratings, and package sizes.  

For exact technical specifications, always refer to the official **PULSE T1144 datasheet**.
