Long Beach, Calif. - Achieving maximum space savings just got easier with J.W. Miller's new PMA series of surface-mount multilayer ferrite chip bead arrays. The new arrays pack four ferrite beads in a single package, which allows for handling of four separate lines simultaneously. Designed for high performance EMI suppression in multiple-line circuits, the PMA devices exhibit high reliability and stability.
The PMA Series incorporates multilayer construction and magnetically shielded circuits to prevent coupling and to ensure optimal signal integrity. Performance characteristics include an impedance range of 30 to 1000 ohms, a DC current range of 100 to 350 milliamps, and an operating temperature range of -55 to 125 degrees C. Terminals are solder coated for wave and reflow soldering.
In addition, the device's small size, 3.2 mm (L) x 1.6mm (W) x 0.9mm (D), makes it suitable for miniature telecommunication devices and portable computer equipment. Applications include cell phones, pagers, hand-held organizers, high-frequency wireless communication devices, notebook computers, printers, network cards, industrial electronics, and entertainment devices.
The PMA chip bead arrays are offered in Type L for low frequency and Type H for high frequency applications. They're available in tape and reel packaging with 3,000 units per reel.
Prices for the PMA devices start at $0.025 in production quantities. Delivery is four to six weeks.
