Applications
The NC20K00103KBA is used in battery management systems and portable electronics where a 10 kΩ NTC thermistor monitors cell or board temperature to trigger thermal cutoff or throttling at defined thresholds. Its 1206 SMT footprint allows integration directly adjacent to high-current components on motor controller PCBs for junction temperature feedback. HVAC control boards and industrial sensing modules also employ this part for ambient temperature measurement in resistor-divider ADC front-ends.

Frequently Asked Questions
What is the nominal resistance of the AVX NC20K00103KBA, and at what reference temperature is it specified?
The NC20K00103KBA has a 10 kΩ nominal resistance at 25°C with ±10% (K) tolerance. This standard NTC reference point allows designers to use straightforward resistor-divider circuits with a 10 kΩ fixed series resistor to generate a mid-scale voltage at room temperature, making ADC interfacing simple in microcontroller-based temperature sensing applications across the -40°C to +125°C range.
Which PCB footprint does the NC20K00103KBA use, and does it suit automated SMT lines?
The NC20K00103KBA uses a 1206 (3.2x1.5 mm) rectangular SMT footprint with a maximum height of 1.5 mm. This package is fully compatible with standard pick-and-place machines and lead-free reflow solder profiles, making it straightforward to incorporate into automated production lines for battery packs, motor drives, or HVAC boards without any through-hole drilling operations.
For a lithium-ion battery management system, how does the NC20K00103KBA help prevent thermal runaway?
In a lithium-ion BMS, the NC20K00103KBA is placed near each cell group where its resistance drops sharply as cell temperature rises above 25°C. The BMS microcontroller reads the thermistor's voltage divider output through a 12-bit ADC; when the equivalent temperature exceeds approximately 60°C, the firmware asserts a charge-disable signal within microseconds. The 10 kΩ at 25°C value ensures a clear measurable voltage span across the 0°C to 80°C battery operating window.
Is there a significant lead time concern when ordering NC20K00103KBA, and how should procurement plan for it?
Yes. The NC20K00103KBA has a factory lead time of 16 weeks from AVX, which is longer than typical commodity resistors or capacitors. Procurement teams should maintain a safety stock of at least 8 weeks of consumption and place blanket purchase orders in advance. Alternatives with 10 kΩ NTC in 1206 SMT from Murata or TDK may offer shorter lead times and can be cross-referenced if the B-constant and tolerance match the design specification.
