Additional Details:

The ACF451832-102-T common mode filter is constructed using a ferrite core and wound with copper wire. The ferrite core provides high impedance to common mode currents, while the winding configuration minimizes the impact on differential mode signals. This allows the filter to effectively attenuate noise without significantly degrading the desired signal.

Technical Specifications:

• Impedance @ 100MHz: 1000 Ohms
• Rated Current: 500mA
• DC Resistance (Max): 0.3 Ohms
• Operating Temperature: -40°C to +85°C

The filter is designed for reflow soldering and is compatible with standard SMT assembly processes. Its small size makes it suitable for dense circuit board layouts where space is limited. The high common mode impedance ensures effective noise suppression in a wide range of applications. TDK's reputation for quality and reliability makes the ACF451832-102-T a trusted choice for engineers seeking to improve the electromagnetic compatibility (EMC) of their products.
