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.
They are designed for a maximum fault current of 100A, and can be used in ambient temperatures up to 125C.
AHR versions of these products will be available for automotive applications that require qualification to the AEC-Q200 specification.
"This product line expansion gives designers the ability to provide resettable overcurrent protection in higher temperature environments", said Karin Kinsman, R-Line Product Manager for Raychem Circuit Protection.
"Their higher temperature capability leads to another advantage in their ability to provide high current-carrying capacity with a flatter thermal derating curve than other devices.
This flatter thermal derating can be a benefit in lower temperature applications where there is a tighter restriction on the ratio of the trip to hold currents over a large temperature range", she added.
PolySwitch RHE400 and RHE1500 devices are UL, CSA, and TUV certified and are available in straight-lead or kinked-lead configurations in bulk packaging, ammo pack, or tape and reel for compatibility with high-volume manufacturing.
