The TDK B59219J0130A020 is an AEC-Q200 subminiature positive temperature coefficient (PTC) thermistor with 560 volts AC, designed for reliable and secure operation in modern electronic equipment. Its high accuracy, low temperature coefficient, and smallest mounting pitch make it ideal for temperature sensing and control applications in a variety of electronic devices. The device is further reinforced with PTC protection, meaning it cuts power at higher temperatures as a safety feature. Its characteristics make this thermistor resistant to temperature shock, creating a long life and resistance to over-temperature and short-circuit conditions. The miniature size and ease of installation make it ideal for circuit board mounting applications, allowing for reduced design cost while maintaining a secure connection.
