Procurement Notes

Verify the specific suffix L002 against official TDK documentation to confirm the exact tolerance and packaging specifications. Ensure the procurement channel provides valid manufacturer traceability. Cross-reference the part number with the latest EPCOS series datasheets to confirm availability and compliance status before finalizing orders.

Selection Notes

Select this component when an 8-ohm initial resistance and 3.7 A steady-state current capacity are required. Consider the 11.5 mm diameter for spatial constraints. Evaluate the ±15% tolerance against circuit sensitivity requirements. Confirm that the through-hole package aligns with the target assembly process and PCB design guidelines.

Part Context

This part belongs to the B57236S series of NTC thermistors manufactured by EPCOS, a TDK Group Company.
