The B59751B0120A070 is a PTC (Positive Temperature Coefficient) thermistor manufactured by EPCOS/TDK. This component is primarily used for overcurrent protection in electronic circuits, as it limits excessive current by rapidly increasing resistance when a certain temperature threshold is reached. Here are the main technical specifications and attributes:
Key Specifications:
- Type: Ceramic PTC Thermistor
- Resistance at 25°C (R25): Approximately 120Ω
- Maximum Voltage: 420V AC
- Current Rating (Holding Current Ih): Typically designed for moderate to low current
- Temperature Range: -40°C to +85°C, providing stable performance across a wide temperature range.
- Package: Radial leaded, disc shape for through-hole mounting
- Functionality: Resettable overcurrent protection fuse
Applications:
- Overcurrent Protection: Prevents damage in circuits by limiting excessive current flow.
- Short Circuit Protection: Ensures protection in systems vulnerable to short circuits.
- Automotive and Consumer Electronics: Used in power supplies, chargers, and other sensitive devices where overcurrent protection is essential.
