Additional Details

The RHDX170 is a disc varistor. Key parameters include the varistor voltage (Vv), which is the voltage at which the varistor starts to conduct significant current, and the maximum surge current (Imax), which is the maximum current the varistor can withstand without failure. It's crucial to select an MOV with a varistor voltage that is slightly higher than the normal operating voltage of the circuit being protected to prevent it from conducting current under normal conditions. The RHDX170 is designed to clamp transient voltages to a safe level, preventing damage to downstream components. The energy absorption capability, measured in joules, is another critical specification, indicating how much energy the varistor can absorb before failing. The fast response time of the MOV ensures that it can quickly clamp voltage surges, protecting sensitive circuits. The RoHS compliance ensures that the RHDX170 does not contain hazardous substances and meets environmental regulations.

The RHDX170 is a reliable and effective solution for surge protection in a wide range of electronic applications. Its high surge current capability, fast response time, and wide operating voltage range make it a versatile choice for protecting sensitive components from transient voltage surges and spikes.
