Manufacturer: PTC (Positive Temperature Coefficient)

Part Number: PT222-001

Specifications:

• Type: PTC Thermistor (Resettable Fuse/Polymeric PTC)
• Operating Voltage: Typically rated for low-voltage applications (exact voltage rating depends on datasheet; common ranges include 6V, 16V, 30V, or 60V).
• Hold Current (I\_hold): Specific current at which the device remains in a low-resistance state (e.g., 100mA, 500mA, etc.).
• Trip Current (I\_trip): Current threshold causing the PTC to "trip" into a high-resistance state (varies by model).
• Max Current (I\_max): Maximum fault current the device can withstand.
• Resistance (R\_min / R\_max): Initial resistance range (e.g., milliohms to ohms).
• Temperature Range: Operating/storage temperature (e.g., -40°C to +85°C).
• Package Type: SMD (e.g., 1210, 1812) or radial leaded, depending on variant.

Descriptions:

• A resettable overcurrent protection device that increases resistance when excessive current flows, limiting circuit damage.
• Self-resets when fault condition is removed and cools down.
• Used in consumer electronics, automotive circuits, and power supplies.

Features:

• Resettable: No need for replacement after tripping.
• Fast Response: Quickly reacts to overcurrent events.
• Compact Design: Suitable for space-constrained PCBs.
• RoHS Compliant: Lead-free and environmentally friendly.

*Note: Exact values depend on the datasheet from PTC (manufacturer).*
