General attention to soldering High soldering temperatures and long soldering times can cause leaching of the termination, decrease in adherence strength, and the change of characteristic may occur. For soldering, please refer to the soldering curves above. Please use a mild flux(containing less than 0.2wt% Cl). lso, if the flux is water soluble, be sure to wash thoroughly to remove any residue from the underside of components, that could affect resistance. Cleaning When using ultrasonic cleaning, the board may resonate if the output power is too high. Since this vibration can cause cracking or a decrease in the adherence of the termination, we recommend that you use the conditions below. Frequency:40kHz max. Output power:20w/iiter Cleaning time:5minutes max. 63

14 NTC Thermistor basic properties Negative temperature coeffcient(ntc)thermistors are manufactured from high purity and uniform materials to achieve a construction of near-perfect theoretical density. This ensures small size, tight resistance and -value tolerances, and fast response to temperature variations, making a highly sensitive and precision component. Thermistor is available in a wide range of types to meet your demands for small size and high reliability. Resistance - temperature characteristic The resistance and temperature characteristics of a thermistor can be approximated by equation 1. R : resistance at absolute temperature T(K) R0 : resistance at absolute temperature T0(K) : value T(K)= t( C) The value for the thermistor characteristics is not fixed, but can vary by as much as 5K/ C according to the material composition. Therefore equation 1 may yield different results from actual values if applied over a wide temperature range. y taking the value in equation 1 as a function of temperature, as shown in equation 2, the difference with the actual value can be minimized. C, D, and E are constants. The value distribution caused by manufacturing conditions will change the constant E, but will have no effect on constants C or D. This means, when taking into account the distribution of value, it is enough to do it with the constant E only. Calculation for constants C, D and E Using equations 3~6, constants C, D and E can be determined through four temperature and resistance value data points (T0, R0). (T1, R1). (T2, R2) and (T3, R3). With equation 3, 1, 2 and 3, can be determined from the resistance values for To and T1, T2, T3 and then substituted into the equations below. Example Using a resistance-temperature characteristic chart, the resistance value over the range of 10 C~30 C is sought for a thermistor with a resistance of 5kΩ and a value deflection of 50K at 25 C. Process Determine the constants C, D and E from the resistance-temperature chart. T= CT 2 +TD+E+50 ; substitute the value into equation and solve for T R= 5exp {T (I/T-I/298.15)} ; substitute the values into equation and solve for R T : ~

15 Results of plotting the resistance-temperature characteristics are shown figure 1 Resistance ratio (Rt / R25) RESISTNCE-TEMPERTURE CHRCTERISTIC(Fig. 1) Resistance temperature coefficient The resistance-temperature coefficient (=) is defined as the rate of change of the zero-power resistance associated with a temperature variation of 1 C at any given temperature. The relationship between the resistance-temperature coefficient (=) and the value can be obtained by differentiating equation 1 above. negative value signifies that the rated zero-power resistance decreases Heat dissipation constant (JIS-C2570) The dissipation constant (@) indicates the power necessary for increasing the temperature of the thermistor element by 1 C through self-heating in a heat equilibrium. pplying a voltage to a thermistor will cause an electric current to flow, leading to a temperature rise in the thermistor. This " intrinsic heating " process is subject to the following relationship among the thermistor temperature T1, ambient temperature T2, and consumed power P. Measuring conditions for all parts in this catalog are as follows: Room temp is 25 C xial and radial leaded parts were measured in their shipping condition. Power rating (JIS-C2570) The power rating is the maximum power for a continuous load at the rated temperature. For parts in this catalog, the value is calculated from the following formula using 25 C as the ambient temperature. (formula) Rated power=heat dissipation constant (maximum operating temperature-25 C) 69

16 Maximum operating power Definition : The power to reach the maximum operating temperature through self heating when using a thermistor for temperature compensation or as a temperature sensor. (No JIS definition exists.) The maximum operating power, when t C is the permissible temperature rise, can be calculated using the following formula. Maximum operating power= theat dissipation constant (3.3) Thermal time constant for changes in surrounding temperature (JIS-C2570) constant expressed as the time for the temperature at the electrodes of a thermistor, with no load applied, to change to 63.2% of the difference between their initial and final temperatures, during a sudden change in the surrounding temperature. When the surrounding temperature of the thermistor changes from T1 to T2, the relation between the elapsed time t and the thermistors temperature T can then be expressed by the following equation. The constant J is called the heat dissipation constant. If t= J, the equation becomes : (T-T1) / (T2-T1) = In other words, the above definition states that the thermal time constant is the time it takes for the temperature of the thermistor to change by 63.2% of its initial temperatrue difference. The rate of change of the thermistor temperature versus time is shown in table 1. Temp. (T) Table-1 Thermal Time Constant Time (t) Measuring conditions for parts in this catalog are as follows: Part is moved from a 50 C envirconment to a still air 25 C environment until the temperature of the thermistor reaches 34.2 C. xial and radial leaded parts are measured in their shipping form. Please note, the thermal dissipation constant and thermal time constant will vary acccrding to environment and mounting conditions 70
