Fastron has introduced the 1812CMF/E, an advanced common mode choke designed specifically for 100BASE-T1 Ethernet data communication. This innovative component is housed in a compact 1812 chip inductor package (4.7 x 3.4 x 2.85 mm), making it an ideal choice for modern, space-constrained applications.
The 1812CMF/E features dual copper wire coils wound around a ferrite core, with a ferrite plate on top to create a closed magnetic circuit. This design not only ensures effective signal integrity but also simplifies automated pick-and-place assembly, enhancing manufacturing efficiency. With an inductance of 200 µH and typical impedance reaching 10 kΩ, the 1812CMF/E-201X delivers exceptional performance in noise suppression and signal filtering, critical for stable Ethernet communication.
Key specifications include a DCR of 4.5 Ω, rated current of 200 mA, and an insulation resistance of at least 10 MΩ, ensuring reliable performance even in demanding environments. Engineered to operate seamlessly across a broad temperature range from -40°C to +105°C (including self-heating), the 1812CMF/E is ideal for use in extreme conditions.
Fully compliant with RoHS standards, the 1812CMF/E is also AEC-Q200 qualified, making it suitable for automotive and other high-reliability applications. Additionally, it supports lead-free soldering, aligning with current industry requirements for environmentally friendly manufacturing.
