The 1206L380SLTH is a PolySwitch Resettable PTC (Positive Temperature Coefficient) from Littelfuse Inc. These devices are used to protect electronic circuits from overcurrent conditions. They are designed to limit the flow of current during a fault, preventing damage to sensitive components, and automatically reset once the fault condition is removed.

Applications:

• USB Port Protection
• Computer Peripheral Protection
• General Electronics Circuit Protection
• Battery Packs

Features:

• Surface Mount Package: 1206 size for automated assembly
• Resettable: Automatically resets after the overcurrent condition is removed
• Fast Trip Time: Quickly responds to overcurrent events
• Low Resistance: Minimal impact on normal circuit operation
• RoHS Compliant: Environmentally friendly

Benefits:

• Overcurrent Protection: Protects circuits from damage due to overcurrent faults.
• Automatic Reset: Reduces downtime by automatically restoring circuit operation after a fault is cleared.
• Space Saving: Small surface mount package allows for compact designs.
• Reliable Protection: Provides consistent and reliable overcurrent protection.
• Cost Effective: Eliminates the need for manual fuse replacement.

Additional Details:

The 1206L380SLTH has a holding current (IHOLD) of 0.38A and a tripping current (ITRIP) of 0.75A. Its maximum voltage rating is 6V, and its maximum interrupt current is 40A. The operating temperature range is typically from -40°C to +85°C. This device is commonly used in consumer electronics, portable devices, and industrial equipment to prevent damage from short circuits and overloads. The datasheet contains detailed electrical and thermal characteristics necessary for proper circuit design and selection. It is important to consider the ambient temperature and the device's thermal derating when selecting a resettable fuse for a particular application.
