Polymeric positive temperature coefficient (PPTC) resettable fuses or polyfuse are in-line current and voltage limiters that protect components from electrical overloads. The CMF-SDP35A-2, developed by China Manufacturers Fuse Group Co. Ltd., is a PTC resettable fuse which offers both over-current and over-voltage protection in a single device.

The CMF-SDP35A-2 is a high-end PTC resettable fuse with a wide range of applications. The device is commonly used to protect automotive systems, automation systems, wired communication networks, power supplies, and consumer electronics from over-current or over-voltage damage.

The CMF-SDP35A-2 features a compact size, low resistance, high interrupting capability, and low voltage drop. When the current running through the fuse exceeds the preset level, the device will begin to generate heat, further increasing the resistance. This process will limit the current flowing through, thereby protecting the connected components from potential damage.

In addition, the CMF-SDP35A-2 is equipped with a temperature fuse inside which will open the circuit if the temperature exceeds the threshold level. This feature provides additional protection by automatically stopping the current flow if the temperature reaches dangerous levels.

The CMF-SDP35A-2 can reset itself if the over-current or over-voltage condition has been cleared. This resetting process can be done manually or automatically. If the temperature is beyond the normal range, the manual resetting process should be performed by either an electrician or engineer, depending on the application.

The CMF-SDP35A-2 has a current rating of up to 40 Amps and an operating voltage range of 2.5 to 120 Volts. It is ideal for high-power applications such as electric motors, as it can cope with the abundant current and high voltages in these applications.

The CMF-SDP35A-2 is a reliable solution for protecting electronic components from electrical overloads. It features a low power consumption, fast response time and high reliability, making it suitable for a variety of applications. With its wide range of current and voltage ratings, the CMF-SDP35A-2 can provide effective protection for both domestic and industrial equipment.
