PTC Resettable Fuses are current sensitive devices that offer overcurrent protection in power distribution systems. These devices are designed to detect an overcurrent condition in an electrical system and open up the circuit, preventing further damage. The SMD300F-2 is a PTC Resettable Fuse (also known as a PolySwitch) designed and manufactured by Littelfuse, Inc. It is used to provide overcurrent protection in small electronics applications.The SMD300F-2 features a low profile, two-terminal surface mount package, making it ideal for space-sensitive applications. It offers overcurrent protection while maintaining a low resistance in normal operating conditions. The SMD300F-2 provides current regulation and short-circuit protection in a wide variety of applications, such as mobile phones, PDAs, digital cameras, laptops, and portable electronics.The SMD300F-2 is a resettable device, meaning that once it detects an overcurrent condition, it will open up the circuit to stop any further damage. Once the problem has been resolved, the device will reset itself and return the circuit to its normal operating condition. The SMD300F-2 can be reset manually or with an automatic reset function. The main advantage of the SMD300F-2 is its small size and low profile. It is only 0.5mm high, making it the ideal choice for small space-sensitive applications. This PTC resettable fuse also offers a high current rating of 300mA and an operating temperature range of -40°C to +85°C, making it suitable for very low temperatures as well as high temperatures.The SMD300F-2 also has a wide voltage rating of 6VAC to 16VAC or 32VDC. This means it can handle high voltage spikes or surges, as well as 10V or more conduction current. Furthermore, it has a small thermal impedance of 0.3°C/W, meaning it can dissipate heat faster and maintain a better overall temperature.The SMD300F-2 offers a superior rating of 25A for 2 seconds, making it reliable in many applications. It is also UL certified for high voltage overcurrent protection, as well as IEC certified for industrial control applications. The working principle of the SMD300F-2 is relatively simple. When it detects an overcurrent condition, it will open up the circuit and prevent further damage. When the overcurrent condition is resolved, the device will reset itself and allow the circuit to return to its normal operating condition. This process repeats each time the device detects an overcurrent condition. The SMD300F-2 is a reliable and efficient PTC resettable device for many small electronics applications. It is designed to protect delicate electronics from overcurrent conditions and provide a low resistance rating during normal operation. Furthermore, its small size and low profile make it ideal for use in space-sensitive applications. The SMD300F-2 is UL and IEC certified, making it reliable and suitable for a wide variety of applications.
