B59201P1080A062

Ptc Resettable Fuses Overview

The B59201P1080A062 is a surface-mount PTC thermistor from the B59201 series, designed for overcurrent protection in automotive applications. It features a 3225 (8063 metric) package and operates within a temperature range of -40°C to +125°C. The component has a rated voltage of 24V and a nominal hold current of 165mA. At 25°C, the typical resistance is 4.6 Ohms with a tolerance of ±25%. It is AEC-Q200 qualified and RoHS compliant.

Ptc Resettable Fuses Feature Summary

• Provides automatic resettable overcurrent protection for sensitive electronic circuits.
• Complies with AEC-Q200 qualification standards for automotive reliability.
• Utilizes ceramic construction for stable performance across wide temperature ranges.

Ptc Resettable Fuses Applications

• Automotive electronics circuit protection
• Overcurrent safeguarding for low-voltage DC lines
• Protection of sensors and control modules

Ptc Resettable Fuses Procurement Notes

Verify that the specific part number matches the required hold current and voltage ratings for the target application. Confirm AEC-Q200 compliance if automotive grade certification is mandatory. Ensure the 3225 package dimensions align with the PCB footprint design. Check datasheet limits for trip current and maximum working temperature before finalizing procurement.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable fuse is needed for 24V automotive systems requiring approximately 165mA hold current. The 4.6 Ohm initial resistance suits low-power signal or control lines rather than high-current power rails. Consider the 3225 package size for board space constraints. Verify thermal management requirements as the device self-heats during normal operation.

Ptc Resettable Fuses Part Context

This part belongs to the EPCOS B59201 series of SMD PTC thermistors specifically engineered for automotive environments. The series offers various hold currents and resistances within standardized EIA packages like 3225 and 4032. These components serve as alternatives to traditional fuses by providing automatic recovery after fault conditions clear.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other B59201 series variants with similar electrical characteristics but different hold currents or resistances. Cross-reference datasheets for equivalent AEC-Q200 qualified parts from TDK Electronics ensuring matching voltage ratings and package dimensions.
