NTC 8D-11 Thermistor

🔹 NTC 8D-11 Inrush Current Limiter – Power Thermistor, 8Ω 3A

The NTC 8D-11 is a power NTC thermistor designed to limit inrush current in power supplies and electronic equipment. It provides soft-start protection by reducing its resistance as it heats up, protecting sensitive components from surge currents during power-up.

✅ Specifications:

Zero Power Resistance (R25): 8Ω ±20%

Maximum Steady-State Current: 3A

B-Value (B25/50): 2800K

Body Diameter: 11mm

Thermal Time Constant: ~50s

Operating Temperature: -40°C to +175°C

📦 Pin Configuration:

Lead 1: Thermistor terminal

Lead 2: Thermistor terminal

📦 Features:
✔️ Low initial resistance (8Ω) to allow power-up while limiting current
✔️ Self-heating reduces resistance to minimize power loss during normal operation
✔️ Cost-effective inrush current suppression
✔️ Fast response time for effective surge protection
✔️ Epoxy-coated disc construction for durability and insulation

📦 Applications:
✔️ Inrush current limiting in switching power supplies (SMPS)
✔️ UPS and inverter systems
✔️ Electronic ballasts for lamps
✔️ Motor soft-start and control circuits
✔️ Battery chargers and power adapters
