ACT45B-510-2P-TL003
Category
The TDK ACT45B-510-2P-TL003 is a high-performance common mode filter optimized for EMI suppression in compact electronic systems. With its 51µH inductance at 100kHz, 2.8kΩ impedance at 10MHz, and 50V DC rating, it effectively filters noise in communication devices, power supplies, and industrial controls. The SMD 4.5x3.2mm package enables space-efficient designs while maintaining operational stability from -40°C to +150°C. Engineers should prioritize proper thermal management and ESD protection during soldering and testing, with application extended to medical and automotive systems requiring robust EMI performance.
