Description

The 2920L075DR is a specific model of PolySwitch (resettable fuse) manufactured by Littelfuse. It is designed to protect electronic circuits from overcurrent conditions. Unlike traditional fuses that need replacing after one-time use, the PolySwitch can reset itself once the fault condition is removed, allowing for ongoing protection without maintenance.
Key features of the 2920L075DR include a maximum operating voltage and a hold current of 0.75A, with a trip current of 1.5A. It is designed for use in a variety of applications, including telecommunications, automotive, and consumer electronics, where it's essential to safeguard components from unexpected current surges.
The device comes in a surface-mountable 2920 package, which refers to the standard dimensions of 7.4mm x 5.5mm x 1.1mm, making it suitable for compact circuit designs. This component offers reliability and cost-efficiency, reducing downtime and the need for manual fuse replacement. It is a critical component for enhancing device longevity and maintaining safety standards in electronic circuit designs.

Equivalent

The 2920L075DR is a PTC resettable fuse from Littelfuse. Equivalent products include:
1. Bourns MF-R075
2. TE Connectivity RUEF075
3. Murata PRG21BC751QB1RB
These alternatives are similar in terms of hold current (0.75A) and voltage ratings. Always verify specifications and compatibility with your application before substituting.

Features

The 2920L075DR is a surface-mount Polymeric Positive Temperature Coefficient (PPTC) resettable fuse. It is designed to protect electronic circuits from overcurrent conditions. Key features include:
1. Resettable Functionality: Automatically resets after the fault condition is cleared, allowing for repeated use without replacement.
2. Current Rating: Typically rated at around 0.75A hold current at 25°C.
3. Voltage Rating: Maximum voltage of 60V DC.
4. Fast Response Time: Quickly reacts to overcurrent events to protect circuits.
5. Low Resistance: Offers low initial resistance, minimizing power loss.
6. Compact Size: Suitable for surface mount technology, saving space on PCBs.
7. Wide Operating Temperature: Operates effectively within a broad temperature range, often from -40°C to +85°C.
8. RoHS Compliant: Meets environmental and safety standards for hazardous substances.
These features make the 2920L075DR a reliable choice for applications requiring overcurrent protection in compact electronic devices.

Pinout

The 2920L075DR is a PolySwitch resettable PTC (Positive Temperature Coefficient) fuse made by Littelfuse. It serves to protect electrical circuits from overcurrent conditions by increasing its resistance significantly when a certain threshold temperature is reached, effectively limiting the current flow.
The "2920" refers to the dimensions of the device in mils (2900 by 2000 mils), which translates to approximately 7.4 mm by 5 mm. The "075" in the part number indicates the hold current, which is 0.75 A.
Regarding pin count, the 2920L075DR is a surface-mount device and typically has two terminals for connection to a circuit. These terminals are used to connect the device in series with the circuit it is intended to protect.
It is important to note that the specific function and behavior of the device can vary depending on the application and the surrounding components. Always refer to the manufacturer's datasheet for detailed specifications and guidelines for usage.
