Product Detailed Introduction
The MF52 series is a high-performance bead-type NTC thermistor
encapsulated with high-quality epoxy resin, developed with advanced
materials and precision manufacturing technology. Featuring
miniature size, compact structure and excellent airtightness, this
thermistor effectively prevents moisture and dust erosion, ensuring
long-term stable operation in harsh environments. It delivers
ultra-fast temperature response and high measurement accuracy, with
consistent electrical performance and superior interchangeability,
avoiding data deviation caused by component replacement.
Equipped with insulated enameled copper wires with tin-plated
terminals, the product features excellent conductivity, easy
welding and installation, and strong anti-oxidation capability.
With a dissipation coefficient of 2.0mW/℃ and low power
consumption, it avoids self-heating interference during temperature
detection, greatly improving measurement authenticity. Supporting
wide-temperature operation and multiple precision specifications,
it can be customized in wire length and appearance size according
to customer demands.
Widely applicable for temperature measurement, monitoring and
overheating protection in air conditioners, heating equipment,
electronic thermometers, automotive electronic systems, lithium
battery packs, smart home devices and industrial control equipment.
All products undergo strict quality testing to meet global
mainstream industry standards, providing reliable and
cost-effective temperature sensing solutions for global customers.
