This component features a nominal resistance of 30kΩ at 25°C with a resistance tolerance of ±2%, ensuring consistent baseline accuracy for control systems. The thermistor is characterized by a B-constant of 3982K with a tight tolerance of ±1%, providing a predictable resistance-temperature curve essential for accurate signal conditioning and feedback loops in industrial and automotive applications. Designed for robust mechanical integration, this thermistor utilizes a ring lug configuration, allowing for secure surface mounting to heat sinks, chassis, or power modules via a threaded fastener. The assembly includes 75mm leads, facilitating flexible routing within complex enclosures or crowded PCB layouts. This ring lug thermistor is well-suited for monitoring critical thermal thresholds in power electronics, battery management systems, and motor drive assemblies where direct thermal coupling is required to maintain operational safety and prevent thermal runaway. ## Specifications | Parameter | Value | |---|---| | Svhc | Lead (04-Feb-2026) | | B-Constant | 3982K | | Lead Length | 75mm | | Ntc Case Size | - | | Product Range | 213865 Series | | Qualification | - | | Thermistor Type | Ring Lug | | Resistance (25°C) | 30kohm | | B-Constant Tolerance | ± 1% | | Resistance Tolerance (25°C) | ± 2% | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:4432132/) ## **Product Datasheet** Part Number Found ## **Limited Information Available** This part is not formally published to our online part catalog.
