The MISM-7R-15-20 is a surface mountable resettable Polymeric Positive Temperature Coefficient (PPTC) device designed and manufactured by Littelfuse, Inc. This device is part of the miniSMDC series and is intended for overcurrent protection in various electronic applications.
Key features of the MISM-7R-15-20 include:
1. Hold Current (Ihold): The device has a hold current of 0.15 Amps at room temperature, meaning it will not trip until the current exceeds this level.
2. Trip Current (Itrip): The trip current is 0.30 Amps, which is the current level at which the device will transition from a low-resistance state to a high-resistance state to protect the circuit.
3. Maximum Voltage Rating: The maximum voltage rating for the MISM-7R-15-20 is 6V, suitable for low-voltage applications.
4. Resettable: One of the main advantages of the PPTC devices is that they can be reset after a fault condition has been removed from the circuit.
5. Fast Time-to-Trip: The device has a quick time-to-trip characteristic which ensures fast response to fault conditions.
6. Small Size: With dimensions of 4.0mm x 3.2mm x 0.9mm, the MISM-7R-15-20 is designed to take up minimal board space which is ideal for densely packed electronic boards.
7. Operating Temperature Range: It features a wide operating temperature range from -40°C to 85°C, suitable for various environments and applications.
8. RoHS Compliant: The device complies with RoHS standards, ensuring that it is free from harmful substances such as lead and cadmium
