T/XJZJXH 0003-2025 Detailed specification of MF5605 type thermistor

Scope

This document specifies the detailed technical requirements, product quality assurance requirements, delivery preparation, and specific testing methods for the MF5605 thermistor (hereinafter referred to as the thermistor). This document applies to thermistor production process control, supplier selection, qualification inspection, quality consistency inspection, and user acceptance. 1) All test conditions comply with the provisions of GJB601B-2018 *General Specifications for Thermistors* and GJB360B-2009 *Test Methods for Electronic and Electrical Components*. For user application conditions that exceed the test conditions specified in the above standards, detailed specifications will be provided; 2) The test conditions for destructive physical analysis (DPA) fully comply with the provisions of GJB4027A-2006 *Destructive Physical Analysis Methods for Military Electronic Components*; 3) Nominal zero power resistance value: The nominal zero power resistance value range of this specification is 10KΩ～500KΩ, and the B value range is 220K～800K, with a large adjustable range. Customized products with different specifications can be provided according to user requirements; 4) The external dimensions can also be customized according to user needs; 5) Resistance ratio and B value are two different parameters characterizing the same property of the thermistor from different perspectives and methods, and the test conditions for them are also different. Domestic thermistor developers, manufacturers, and users are accustomed to using B value. GJB601B-2018 adopts resistance ratio, but this specification stipulates B value and its test conditions, without specifying resistance ratio and test conditions; 6) Short-term load and load life: When the actual maximum power of the user is <1mW, this specification stipulates the maximum rated power as 1mW; 7) Low-temperature storage: Using liquid nitrogen (77K) as the lowest operating temperature medium for low-temperature
