01005 Size Jumper Resistor Resistant to Sulfur-Induced Open Failures

RK73Z-RT

KOA has expanded its RK73Z-RT anti-sulfur jumper resistor series with the introduction of the RK73Z 1F-RT, a 01005-inch-size model.
These anti-sulfur resistors utilize highly sulfur-resistant materials for their internal electrodes, preventing open-circuit failures caused by sulfurization.
In recent years, demand for further miniaturization and lower power consumption has been increasing in electronic devices, including optical modules for data centers.
The new 01005-inch-size RK73Z 1F-RT enables more compact, high-density mounting. The RK73Z-RT series also offers excellent anti-sulfur performance, providing high reliability even in environments where exposure to sulfur is a concern.

Applications: Equipment used in environments where sulfur gases are present (e.g., hot spring facilities, wastewater treatment facilities, and chemical plants)
