Construction Features High mechanical strength and reliability are available due to thermistor film and glass-coated structure on alumina substrate. Thickness is fixed not related to resistance value. Thinner than the multilayer type. Application Temperature compensation for transistor, IC and crystal oscillator in mobile communications Temperature sensor for rechargeable batteries Temperature compensation of LCD Temperature compensation and sensing in automobile entertainment such as CD, MD and Tuner Temperature compensation in general use of electric circuits Type Designation Dimensions Unit mm Type (inch) L W C d t TSN04(0402) 1.000.05 0.500.05 0.200.10 0.250.10 0.350.05 TSN06 (0603) 1.600.10 0.800.10 0.300.20 0.300.2 0.450.1 Reliability Tests Rating & Characteristics Resistance-Temperature Characteristics Recommended Because the TAI TSR product uses a resistive film technology the following points should be considered when designing into the circuit. 1. The self-heating, generated by the component, may change its own resistance value. 2. Review the heat resistance data because at elevated temperatures, above 70 , the TSR component may have significant resistance drift which should be accounted for in the circuit design. 3. Exposure to: harsh ultrasonic cleaning after mounting; shower washing; covering with masking tapes may cause the termination(s) to peel. Caution should be taken when cleaning is performed. 4. Please follow all ESD safety rules to prevent any unwanted changes in the resistance value. An ESD event as small as 300V could cause a change in resistance. 5. The resistors can be damaged by the following: sulfuric acid, hydrogen chloride, sulfurous acid, nitrogen oxides (NOx) and hydrogen sulfide. a. The acid gases can corrode the coatings, films and/or electrodes causing the resistance value to change. b. Hydrogen Sulfide gas, even in amounts of a few ppm concentrations, can cause the inner electrodes to form Flowers of sulfur, which could result in the termination disconnecting from the resistive paste. 6. Coating, potting and molding can affect the mounted components resistance value. (e.g. expansion or shrinkage of the resistor overcoat, resistance drift) 7. Fail-safe design: To prevent serious damage to human, animal and plant life, please use appropriate "fail-safe" measures (e.g. using protective circuits or equipment, circuit redundancy) especially where the applications require a high reliability (e.g. medical, traffic or transportation, signals, aerospace, fuel or gases and other critical applications, which may not be listed). 8.
