The AP Series thermistor offers ultra-high accuracy, exceeding even our high-precision AT thermistors. With tight R25 and B25/85 tolerance levels (±0.5%), it ensures stable and reliable performance across various applications.
These thermistors maintain 0.5% resistance tolerance across a wide temperature range of –60°C to +70°C, making them ideal for critical environments where precision is key.
SEMITEC’s AP thermistors are fully compliant with RoHS Directive 2011/65/EU.
Applications include mobile devices, battery packs, fan motors, automotive systems, office automation, home electronics, security systems, thermometers, measuring instruments, and more..
