J.W. Miller introduces the PMA Series of SMT Multilayer Ferrite Chip Bead Arrays designed for high performance EMI suppression in multiple-line circuits. The PMA Series features four ferrite beads in a single package, which allows handling of four separate lines simultaneously. The device's small size, 3.2 (L) × 1.6 (W) × 0.9 mm (D), makes it suited for miniature telecommunication devices and portable computer equipment. The PMA Series incorporates multilayer construction and magnetically shielded circuits to prevent coupling and ensure optimal signal integrity. Performance characteristics include impedance range of 30 to 1000 Ω, DC current range of 100 to 350 mA, and an operating temperature range of 55°C to +125°C. Terminals are solder coated for wave and reflow soldering. The PMA Series is offered in Type L for low frequency and Type H for high frequency applications.
