The Amphenol Thermometrics YM120D125N450 is a PTC resettable fuse from the YM Series, designed for overcurrent and overvoltage protection. It features a ceramic PTC element with a nominal resistance of 45Ω at 25°C and a tolerance of ±20%. The device can handle a maximum operating voltage of 265V RMS and a continuous current of 110mA without tripping at 25°C.
This PTC thermistor has a switch temperature of 120°C and a minimum trip current of 155mA at 25°C. It can withstand overload currents up to 0.7A and has a maximum residual current of 5mA. The operating temperature range is 0°C to 55°C at maximum voltage, with a storage range of -25°C to +155°C.
The component is housed in a radial disc package with a silicone resin coating (black) and tin-coated copper leads. It measures 7.00mm in diameter and 4.50mm in thickness, with a maximum height of 9.50mm and a lead spacing of 5.08mm. The through-hole mounting design is suitable for automatic PCB insertion.
