The PBRC400BRVA is a series of resettable fuses (also known as Polymeric Positive Temperature Coefficient or PPTC devices) manufactured by AVX Corporation. These devices are designed to protect electronic circuits from overcurrent conditions by increasing their resistance significantly when a fault occurs, effectively limiting the current flow.

Applications

• USB port protection
• Battery packs
• Mobile phones
• Game consoles
• Hard drives
• Power supplies
• General electronic circuit protection

Features

• Resettable Functionality: Returns to its low-resistance state after the overcurrent condition is removed.
• Solid-State Construction: More robust than traditional fuses, with no glass or ceramic components.
• Fast Trip Time: Reacts quickly to overcurrent events to protect sensitive components.
• Low Resistance: Minimal impact on circuit performance under normal operating conditions.
• Compact Size: Allows for use in space-constrained applications.
• RoHS Compliant: Compliant with Restriction of Hazardous Substances directive, making it environmentally friendly.

Benefits

• Enhanced Circuit Protection: Protects against damage from overcurrent and short-circuit conditions.
• Reduced Downtime: Resettable functionality eliminates the need for fuse replacement after each overcurrent event.
• Increased Reliability: Solid-state construction provides greater durability and longer lifespan.
• Cost Savings: Eliminates the cost of replacing blown fuses.
• Improved Safety: Prevents overheating and potential fire hazards.

Additional Details

The PBRC400BRVA's specific characteristics (e.g., trip current, hold current, voltage rating, resistance) are detailed in the datasheet. These parameters must be carefully selected to match the requirements of the protected circuit. The '400' typically relates to the hold current in mA. They are generally surface mount devices. Proper soldering techniques are crucial for reliable performance. The datasheet contains information on recommended soldering profiles and handling precautions.
