Interconnections & Packaging: Ferrite-Chip-Bead Array Houses Four Beads In One Package

The PMA series of surface-mount multilayer ferrite-chip-bead arrays features four ferrite beads in a single package measuring just 3.2 by 1.6 by 0.9 mm, allowing the handling of four separate lines simultaneously. The arrays especially suit miniature telecom devices and portable computer equipment. Performance includes an impedance range of 30 to 100 (omega), a 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 series is offered in Type L for low-frequency and Type H for high-frequency applications. Arrays come in tape-and-reel packaging and cost from $0.025 each in production quantities. Delivery is four to six weeks.
