Buying an NTC (Negative Temperature Coefficient) thermistor requires matching the component to your specific circuit needs, whether it's for (where resistance drops as heat increases) or inrush current limiting . 1. Key Selection Parameters
For precision sensing, look for ±1% . General-purpose or protection types often have ±5% to ±20% .
This represents the sensitivity of the thermistor. A higher B-value means a larger resistance change per degree of temperature. buy ntc thermistor
Standard epoxy-coated types typically handle -55°C to +155°C , while glass-encapsulated versions can go up to +300°C . 2. Where to Buy
When browsing, look for these specific values on the datasheet or product listing: The most common values are 10kΩ and 100kΩ . General-purpose or protection types often have ±5% to ±20%
For Arduino or DIY projects, ElectroPeak and GrayLogix offer affordable modules (3-pin or 4-pin) that are easier to wire.
You can find these components through specialized electronics distributors or general retailers: For Arduino or DIY projects
For high precision and bulk orders, sites like Mouser Electronics, Newark/element14 , and LionCircuits carry top brands.
