NTC Thermistor DKARDU 10PCS 10K/100K 1 Percent Accuracy High

Description

Product Overview

The DKARDU NTC thermistor collection is engineered for precision temperature sensing in demanding industrial environments. Each package contains ten thermistors, split evenly between 10kΩ and 100kΩ resistance values, both calibrated to a tight 1 percent tolerance. The devices operate reliably from -50°C up to 125°C, offering a broad measurement window that accommodates everything from cryogenic monitoring to high‑temperature process control. The thermistors employ a classic MF52D 3435/3950 ceramic composition, delivering a predictable resistance‑temperature curve that simplifies integration into analog and digital control systems. Their leads are fashioned from PVC, a flame‑retardant material that resists mechanical fatigue, ensuring long‑term durability even in vibration‑prone installations. The compact form factor—60mm for the 10k variant and 100mm for the 100k variant—makes them easy to mount on printed circuit boards, within enclosures, or as probe extensions for direct contact with hard‑to‑reach surfaces.

Usage

These NTC thermistors are versatile components suitable for a wide range of applications. In industrial automation, they serve as temperature feedback elements for motor drives, heating elements, and refrigeration units, enabling precise control loops that improve energy efficiency and product quality. In laboratory instrumentation, the high sensitivity and low tolerance make them ideal for calibrating temperature‑dependent circuits, compensating for thermal drift in precision amplifiers, and providing cold‑junction compensation in thermocouple measurement systems. The small probe design allows installation in tight spaces such as valve bodies, pipe interiors, and electronic enclosures where conventional thermometers cannot reach. Additionally, the thermistors are compatible with popular microcontroller platforms, making them a favorite among hobbyists and engineers developing IoT temperature monitoring solutions. Their robust PVC leads tolerate repeated bending, which is especially valuable in prototype rigs that undergo frequent re‑configuration.

FAQ

What is the difference between the 10k and 100k thermistor variants?

The 10k variant provides higher sensitivity around room temperature, making it ideal for applications where small temperature changes need to be detected precisely. The 100k variant offers a broader resistance range, which is useful for circuits that require a larger voltage swing or for cold‑junction compensation in thermocouple setups.

Can these thermistors be used with microcontroller ADC inputs?

Yes. The thermistors can be connected to an analog‑to‑digital converter (ADC) on most microcontrollers. By forming a voltage divider with a known reference resistor, you can convert the resistance change into a voltage that the ADC can read, then apply the Steinhart‑Hart equation to calculate temperature.

How do I compensate for the self‑heating effect of the thermistor?

Self‑heating is minimized by using a low excitation current, typically in the range of 0.1 mA to 1 mA, depending on your circuit requirements. Selecting an appropriate series resistor and limiting measurement duration also helps reduce temperature rise caused by the measurement current.

Are the PVC leads suitable for high‑temperature environments?

PVC leads are rated for continuous operation up to about 105°C. For applications that exceed this temperature, consider using a high‑temperature silicone or PTFE insulated lead, but the core thermistor element itself remains stable up to 125°C.

What warranty and support does DKARDU provide?

DKARDU offers a 12‑month warranty covering manufacturing defects and provides technical support through email and phone. Our engineering team can assist with integration questions, calibration guidance, and troubleshooting to ensure optimal performance of the thermistors in your system.
