PTC Resettable Fuses: 2920L330/24MR Application Field and Working PrinciplePTC resettable fuses, also known as polymeric positive temperature coefficient (PPTC) devices, are circuit protection devices specifically designed to protect electronic equipment and systems from over-current events. When an abnormal current flows through the device, it trips and the current is blocked. The device then needs to be manually reset for the normal current to flow again. The 2920L330/24MR from Littelfuse is one such device. This article will discuss the application fields and working principles of this device.The 2920L330/24MR is a single-use, RoHS compliant polymeric PTC fuse which is designed to protect circuits against a wide variety of over-current and short circuit conditions. This device is housed in a compact, surface mount package and is UL Recognized for up to 5A. It is ideal for use in consumer electronics, such as cell phones, power supplies, and AC adapters. It can also be used in harsh environments and higher pressure systems such as automotive, aerospace, and military applications.The 2920L330/24MR works on the principle of the positive temperature coefficient (PTC) effect. When the current through the device increases beyond its rated value, the temperature of the PTC element inside the device rises, resulting in an increase in its resistance. This further limits the current through the device, temperature is maintained at a safe level, and the circuit is protected against damage. When the over-current condition is removed, the PTC device cools down and automatically resets itself.The 2920L330/24MR device has several safety and reliability features. It is equipped with an over-temperature detection circuit which acts as an additional layer of protection for the device against conditions which could cause overheating. It also has an optional bypass function which can be enabled by connecting two leads on the device to provide a small amount of current in the circuit during a over-current event.In addition, the 2920L330/24MR has a low standing current and a low resistance at moderate temperatures. This ensures smooth and efficient operation of the device with minimal power dissipation, allowing the device to be used in a variety of applications.In summary, the 2920L330/24MR is a versatile and reliable polymeric PTC resettable fuse suitable for use in a wide range of industrial, automotive, aerospace and consumer application. This device works on the principle of the positive temperature coefficient (PTC) effect and is equipped with a variety of safety and reliability features. It has a compact surface mount package and is UL recognised for up to 5A, making it an ideal choice for providing protection in complex electronic systems.
