Resettable fuse protects latest AAAA NiMH cells
New from Raychem Circuit Protection, the MAC300 PolySwitch resettable fuse is custom designed for the new AAAA NiMH cells with increased capacity in a smaller space.
Available with rated hold currents of 550 and 750mA, they are designed to help limit current in the event of power cross faults on the coaxial cable, such as might be generated by phase lags in a multiphase power distribution system.
"The decision to coat these devices was made in response to customer requests for insulated devices for use in large cable electronic boxes, and a growing market demand for higher hold currents", said Lisa Leo, Telecommunications Market Manager for Tyco's Raychem Circuit Protection division.
The BBR550 and BBR750 devices are available in straight lead or kinked lead configurations, and are supplied in tape and reel packaging for compatibility with high-volume assembly.
