Circuit Protection - Home Entertainment
Home Entertainment
From high-speed digital interfaces, such as HDMI and USB 3.0, to low voltage power inputs, to networked interfaces, we help you get protected against failures, damage, and downtime.
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.
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.
When an unsuitable or faulty USB cable is plugged into the USB port, the applied voltage, polarity and permitted current may exceed the specifications of the power regulation circuits. 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.
Current-limiting devices are most important in protecting entertainment systems from long duration faults, during which joule heating can result in a fire hazard, or can damage thermally sensitive components. Our Polyswitch devices limit the flow of dangerously high currents.
PESD help shunt ESD away from sensitive circuitry in electronic devices without inducing signal distortion.
DC electric motors can overheat and cause damage to temperature sensitive components. To help protect these components, custom made PolySwitch devices can be designed for specific customer applications. Installing a PolySwitch device in close proximity to the motor offers the added benefit of limiting current due to excessive heat.
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.
PolySwitch resettable devices can be used to help protect the delicate printed circuit board traces against damage caused by overcurrent conditions.
An overcurrent / overtemperature event may occur in a battery cell due to short circuit, abusive charging or charger failure. PolySwitch axial-leaded devices help protect against overcurrent or overtemperature faults.
