Frequently Asked Questions
What makes the ERX3SJ1R0 suitable for safety-critical circuit designs?
The ERX3SJ1R0 is rated to IEC60115-4 flame-proof standard, meaning it is designed not to propagate flame during fault conditions. With a 3W power rating and 1.0Ω resistance, it safely handles inrush and overload events in industrial power supplies and motor drive circuits operating up to 350V.
How does the ERX3SJ1R0 perform in high-current inrush limiting applications at 24V?
At a 24V rail, the 1.0Ω ERX3SJ1R0 limits steady-state current to 24A theoretical maximum, but its 3W continuous power rating constrains practical operation to approximately 1.73A continuous, making it effective for low-side current sensing and startup inrush attenuation in DC power systems.
What lead and package dimensions should be considered when designing a PCB for the ERX3SJ1R0?
The ERX3SJ1R0 has a 0.8mm lead diameter and 38mm lead length, and the axial through-hole mounting style requires 2 drilled PCB holes spaced to the body length. The tubular body typically spans about 11mm, which designers must account for when allocating vertical board clearance in through-hole layout designs.
