PTC Resettable Fuses are a form of Polymeric Positive Temperature Coefficient (PPTC) Resettable Fuses. They are used to protect circuits from overcurrent and are typically found in laptop chargers, audio/visual equipment, power supplies, consumer electronics, automotive electronics and industrial applications. The LTP190F is part of this family and offers the following features:

Features:

• Wide operating temperature range of -40°C to 125°C.
• Excellent resistance to vibration, shock, and humidity.
• High-temperature performance.
• Small size.
• Low power consumption.
• Minimal heat generation.

The LTP190F PTC Resettable Fuse uses a temperature sensitive polymer based material that changes from a low resistance state to a high resistance state when an over-current is detected. This effectively breaks the circuit and prevents further damage to the device. When the current is reduced to safe operating levels, the PTC will return to its low resistance state.

LTP190F PTC Resettable Fuses have a current rating of 1.9A, a fault voltage of 6V, and a maximum trip current of 4A. They are available in various case sizes ranging from 5mm x 5.4mm to 10mm x 25mm. Due to their low power consumption and minimal heat generation they can be used in many different types of circuit protection applications. From data communication lines to battery charging circuits, these are an ideal choice for designers looking for an efficient and reliable form of protection against current overload.

The LTP190F PTC Resettable Fuse is a highly reliable and cost-effective solution for circuit protection in a variety of applications. Its small size and ability to quickly reset itself ensures that the user does not have to constantly replace fuses and reset circuits each time an over-current is detected. Furthermore, its low power consumption and high temperature performance make it an ideal choice for designers looking for an efficient and reliable form of circuit protection.
