Ptc Resettable Fuses Procurement Notes

Verify the exact part number YM120D170N250 against manufacturer datasheets to confirm electrical ratings including the 161mA current rating and 265V maximum voltage. Ensure the 25-ohm resistance value matches system requirements. Confirm radial lead spacing and thermal limits align with the target application environment before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when a self-resetting fuse is required for low-current circuits up to 161mA. The 25-ohm initial resistance must be compatible with the circuit's standby power consumption. Verify that the maximum operating temperature of 55°C suits the ambient conditions. This radial package is suitable for applications requiring robust mechanical attachment on printed circuit boards.

Ptc Resettable Fuses Part Context

This part belongs to the YM series of PTC thermistors from Amphenol Advanced Sensors. These devices are engineered as resettable fuses, offering a reusable alternative to traditional one-time fusible links. The series provides reliable overcurrent protection for sensitive electronic components in various industrial and consumer applications.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 25-ohm resistance, 161mA trip current, and 265V rating. Verify radial lead configuration and thermal characteristics. Consult official cross-reference lists for confirmed equivalent part numbers from Amphenol or other manufacturers.
