Frequently Asked Questions
What is the nominal resistance of the NC20KC0100KBA at room temperature, and how does it affect circuit design?
The NC20KC0100KBA has a nominal resistance of 100 kΩ at 25°C. This high impedance pairs well with microcontroller ADC inputs in voltage-divider circuits, allowing the use of a matching 100 kΩ reference resistor to achieve approximately 1.65 V midpoint output at 25°C on a 3.3 V supply — well within the typical ADC input range of most 10-bit or 12-bit embedded processors.
How does the SMT package size of NC20KC0100KBA suit battery-powered temperature monitoring designs?
The 3.2 mm × 1.5 mm SMT chip footprint occupies minimal board area while enabling standard reflow soldering at up to 260°C peak. In battery-powered IoT nodes operating at 1.8 V to 3.3 V, the 100 kΩ NTC characteristic limits self-heating current to well under 1 µA at typical measurement bias, preserving battery life during continuous thermal monitoring over temperature ranges from -40°C to +125°C.
Is the NC20KC0100KBA suitable for HVAC or refrigeration systems that require wide temperature range sensing?
Yes. NTC thermistors with 100 kΩ resistance at 25°C exhibit steep resistance changes over wide temperature spans. For HVAC applications monitoring air duct temperatures from -20°C to +85°C, the NC20KC0100KBA provides easily measurable resistance shifts of several tens of kΩ across that range. Its REACH-compliant, RoHS-compatible materials also meet the regulatory requirements common in European HVAC equipment markets.
What package dimensions and mounting style does the NC20KC0100KBA use, and how does it compare to leaded NTC thermistors?
The NC20KC0100KBA is a rectangular SMT chip measuring 3.2 mm × 1.5 mm in length and height, with surface-mount termination pads. Unlike leaded through-hole thermistors that require drilling and hand soldering, this SMT chip is compatible with automated pick-and-place machines and reflow ovens, reducing assembly time and enabling placement densities of over 50 components per square centimeter on modern PCBs.
