Safeguard the most complex office machines and communications equipment on the market from damage from electrical hazards and power faults with circuit protection solutions from TE Connectivity.
PolySwitch devices limit the flow of dangerously high currents during fault conditions that can occur when and reset back to normal operating mode once the fault condition is removed.
An electrostatic discharge or ESD event can result in damage to the device. Extrememly low capacitance ESD protection devices such as our PESD devices help shunt ESD away from sensitive circuitry without inducing signal distortion.
An overcurrent / overtemperature event may occur in a battery cell due to short circuit, abusive charging or charger failure. PolySwitch axial-leaded and disk devices help protect against overcurrent or overtemperature faults.
PESD help shunt ESD away from sensitive circuitry in electronic devices without inducing signal distortion.
A PolySwitch resettable device can be thermally linked to the LCD glass can protect the power module is the control circuitry fails to turn off the element and help prevent thermal runaway.
PolySwitch resettable devices can be used to help protect the delicate printed circuit board traces against damage caused by overcurrent conditions.
When an unsuitable or faulty USB cable is plugged into the USB port, the applied voltage, polarity and permitted current may exceed the device specifications. This can damage the equipment and could become a safety concern. PolySwitch devices limit the flow of dangerously high currents during fault conditions and reset back to normal operating mode once the fault condition is removed; while PolyZen devices help clamp the voltage and shunt excess power to ground.
Hard-disk drives must be protected from incorrect voltages due to misconnection of 12V, 5V, and/or 3.3V lines during installation. The variations in the host-computer power supplies may also result in AC ripple or incorrect polarity that can damage the tantalum capacitors on the drives.
PolySwitch devices help protect against overcurrent and overtemperature fault conditions by limiting the flow of current in the DC input power circuit.
