YQS5878PTF

Overview

The YQS5878PTF is a ceramic PTC thermistor resettable fuse manufactured by Amphenol Advanced Sensors. It features a radial, disc-style through-hole termination suitable for PCB mounting. The component has a maximum operating voltage of 240 V and a hold current rating of 45 mA. Its resistance at 25°C is 250 Ohms with a tolerance of +/-20%. The device operates within a temperature range of +10°C to +55°C.

Feature Summary

• Provides automatic circuit protection by resetting after fault conditions clear
• Utilizes ceramic PTC material for thermal stability
• Designed for radial through-hole PCB integration

Applications

• Overcurrent protection in electronic circuits
• Battery pack safeguarding systems
• Power supply input protection

Procurement Notes

Verify the specific electrical ratings against the official datasheet before procurement. Confirm that the 240 V maximum voltage and 45 mA hold current align with the target application requirements. Ensure the radial package dimensions fit the designated PCB footprint. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a low-current overcurrent protection solution is needed. The 45 mA rating suits sensitive signal lines or low-power control circuits. Consider the 250 Ohm initial resistance impact on circuit operation. Verify that the operating temperature range meets environmental conditions.
