Inrush Current Limiters (ICL) Procurement Notes

Verify component authenticity through authorized Vishay distributors or direct manufacturer channels. Confirm RoHS3 compliance status matches specific project requirements. Ensure storage conditions maintain thermal stability prior to installation. Validate datasheet revisions align with current production batches to guarantee parameter consistency during assembly processes.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required 25Ω resistance value and 120°C transition temperature threshold. Evaluate the 500 VDC rating against peak line voltages in the target application. Consider the 12mm package size for PCB footprint constraints. Assess thermal dissipation capabilities relative to expected duty cycles and ambient operating temperatures within the enclosure design.

Inrush Current Limiters (ICL) Part Context

This part belongs to the CL13 series of inrush current limiters, which offers four resistance values ranging from 7.0 to 100Ω at +25°C. The series is engineered to accommodate various pre-charge times while providing robust protection against high initial surge currents common in capacitive load scenarios across industrial and consumer markets.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference similar 25Ω, 120°C transition PTC thermistors from the same manufacturer family. Verify mechanical dimensions and lead spacing compatibility before substitution. Ensure electrical ratings meet or exceed original specifications to maintain circuit integrity and safety standards.
