Review LITTELFUSE Ld55863 Used

The Littelfuse LD5586-3/LD55863 is a versatile, surface-mount, positive temperature coefficient (PTC) thermistor designed to protect against overcurrent conditions in various electronic applications. This thermistor is available in two different resistance values, 10 ohms and 22 ohms, allowing users to select the best option for their specific circuit requirements.

The LD5586-3/LD55863 thermistor features a compact size, measuring just 3.2mm x 1.6mm, making it suitable for space-constrained designs. Its low profile allows for easy integration into PCBs, and its lead-free RoHS compliant termination makes it an environmentally friendly choice.

The LD5586-3/LD55863 thermistor operates by exhibiting a resistance increase when its temperature rises above a certain threshold. This resistance increase serves as a signal to the circuitry to shut down, preventing further current flow and protecting against potential damage. This self-resetting feature ensures that the circuit can resume operation once the temperature returns to normal.

The Littelfuse LD5586-3/LD55863 thermistor is suitable for use in various applications, such as battery protection, solar panel protection, and LED lighting circuits. Its high thermal stability and low thermal time constant make it an excellent choice for applications where quick response to temperature changes is essential.

The thermistor is available in reel packaging for automated assembly processes, and its wide operating temperature range of -40 C to 155 C ensures that it can perform reliably in a wide range of environments. The LD5586-3/LD55863 thermistor is also capable of handling maximum currents of up to 2.5A, depending on the specific resistance value chosen.

In summary, the Littelfuse LD5586-3/LD55863 is a high-performance, compact, and versatile PTC thermistor suitable for various electronic applications. Its quick response time, self-resetting feature, and RoHS compliance make it a reliable and environmentally friendly choice for designers seeking overcurrent protection solutions.

The Littelfuse LD5586-3/LD55863 is a popular type of circuit breaker used in various applications due to its compact size and high breaking capacity. Here are some pros and cons that can help you make an informed decision about purchasing this circuit breaker:

1. High breaking capacity: The LD5586-3/LD55863 can handle a high current up to 100A, making it suitable for various applications where high current protection is required.

2. Compact size: Despite its high breaking capacity, the circuit breaker has a compact size, which makes it ideal for use in applications where space is limited.

3. Fast tripping action: The circuit breaker has a fast tripping action, which helps to protect against short circuits and overloads quickly.

4. Robust design: The circuit breaker is designed to withstand harsh environments and is resistant to vibration and shock.

5. Easy installation: The circuit breaker is easy to install and can be mounted in various orientations, making it a versatile option for different applications.

1. Limited voltage range: The circuit breaker is designed to work in a voltage range of 24V to 60V DC only, which may limit its use in applications requiring a different voltage range.

2. Higher cost: The LD5586-3/LD55863 may be more expensive than other circuit breakers with similar breaking capacity due to its compact size and robust design.

3. Limited options for mounting: While the circuit breaker can be mounted in various orientations, it may not be suitable for all mounting configurations, which could limit its use in certain applications.

In conclusion, the Littelfuse LD5586-3/LD55863 is a reliable and robust circuit breaker with a high breaking capacity and a compact size. However, its limited voltage range and higher cost may make it less suitable for some applications. It is recommended for use in applications where a high current protection is required in a compact size and where the voltage range is within the specified limits. Overall, the LD5586-3/LD55863 is a good option for those looking for a reliable and compact circuit breaker for their electrical system.
