PTC Resettable Fuses (PPTC) are a type of electric protection device designed with a mechanism that uses a thermally activated polymer to detect circuit faults and then provide overcurrent protection either by opening an internal contact, or by limiting the current through the device. The 2920L050DR is a commonly encountered resettable fuse, and is widely used by many industries because of its fast response time and reliable protection. This article will focus on the application field and working principle of the 2920L050DR.
The 2920L050DR is mainly used in consumer applications such as computers, notebooks, towers, mobile phones, batteries, electronic toys, small electrical appliances, and other electronic products. It can also be found in power supplies, LED drivers, backlighting fixtures, solar power systems, lighting fixtures, portable electronic devices, and other similar products. The device detects and limits current overloads, surge protection, short circuit protection, and temporary excess currents generated by capacitors or inductors.
The device features a 0.5A rating and 30V max voltage. It has a hold current of 140mA, a trip current of 160mA, and a time to trip of 3 seconds minimum. The device can be operated in temperatures between -55 to +150 degrees Celsius. The construction of the device includes a zener diode, a ceramic case, and an activating circuit. The zener diode regulates the current flow, while the ceramic case works as an insulator to prevent damage from over-current, temperature, or circuitry faults. The activating circuit triggers the protection when an overload occurs.
When the current flowing through the 2920L050DR exceeds the trip current of 160mA, the activating circuit will detect the overcurrent and trigger the PTC thermally activated polymer protection. The polymer then generates heat, which rises above the internal temperature setting, causing the PTC element to expand and open the internal contact. This action reduces the current flow to below the hold current of 140mA and allows the device to cool down. Once the temperature is below the internal setting, the PTC polymer re-contracts and returns the device to its conductive state.
The device can be reset multiple times as long as the device temperature remains below the internal temperature setting. However, as temperatures continue to rise, the device will eventually reach its maximum safe temperature and be unable to reset. In that case, it must be replaced. The device is durable and reliable under most normal operating conditions, and will provide adequate protection against over-currents and short circuits.
In conclusion, the 2920L050DR resettable fuse is a popular choice among many industries because of its reliable current protection and fast response time. The device features a 0.5A rating and 30V max voltage, a hold current of 140mA, a trip current of 160mA, and a time to trip of 3 seconds minimum. It protects from overcurrent, surge protection, short circuit protection, and temporary excess currents generated by capacitors or inductors. Because of its temperature sensitivity, the device can be reset multiple times until it eventually reaches its maximum safe temperature and must be replaced.
