## 1. Introduction 

The Taoglas TM41229ANL is a BMS Transformer with Common Mode Choke of 12pins, designed to work in automotive environmental conditions with an operating temperature of -40°C to +125°C. 

The Taoglas Magnetic Product Team have over fifteen years of experience in magnetics design and high-quality manufacturing. With ever expanding product lines, we provide trusted products and services to our customers within a wide range of applications such as: 

- Electric Vehicle 

- Energy Storage Systems 

- Data Center UPS 

- Solar energy storage 

- Renewable Energy 

Taoglas offers a full line of BMS transformers, and common mode chokes for energy storage systems that require serial port safety isolation and EMI noise suppression. These transformers are designed for battery systems with large voltage differences that demand component-to-component isolation. 

The Taoglas BMS Transformers portfolio is intended to perform in highly energy-efficiency modern vehicles such as EVs, HEVs, and PHEVs. 

All Taoglas parts meet AEC-Q200 requirements for automotive applications. For more information on the range of products or for assistance with integration, contact your regional Taoglas customer support team.
