The SDT26A15L05 is a common mode choke manufactured by Yageo. Common mode chokes are passive electronic components used to suppress common-mode noise in electronic circuits. Common-mode noise is unwanted electromagnetic interference (EMI) that appears equally on multiple conductors with respect to a common reference, such as ground. This choke effectively filters out such noise, preventing it from interfering with sensitive electronic equipment.

Applications:

• Power line filtering
• USB data lines
• CAN bus systems
• Ethernet interfaces
• Audio signal lines

Features:

• High common mode impedance
• Low differential mode impedance
• Compact size
• Wide operating temperature range
• High reliability
• RoHS compliant

Benefits:

• Reduces electromagnetic interference (EMI)
• Improves signal integrity
• Enhances system stability
• Prevents equipment malfunction
• Meets regulatory requirements for EMI emissions

Additional Details:

The SDT26A15L05 choke is typically constructed with two or more windings on a common core. The common mode impedance is significantly higher than the differential mode impedance, allowing the choke to effectively attenuate common-mode noise while minimizing the impact on differential signals. The specific inductance and impedance values of the SDT26A15L05 choke are specified in the datasheet. The rated current and voltage are also important parameters to consider when selecting a common mode choke for a particular application. Proper selection of the choke is critical for achieving optimal noise suppression without degrading signal performance. Yageo provides detailed specifications and application notes for the SDT26A15L05 choke to assist engineers in selecting the appropriate component. The choke is designed to be surface mounted onto printed circuit boards (PCBs). The operating temperature range is typically from -40°C to +85°C. The choke is often used in conjunction with other EMI suppression components, such as capacitors, to achieve comprehensive EMI filtering.
