4.0 Performance Parameter

4.1 Resistance(R₉₀)

requirement:R₉₀＝1.084KΩ±1%

test method:90℃±0.1℃.(90℃±0.1℃ in the oil.)

4.2Thermal time Constant(τ)

requirement:τMax15s, τMax18s

test method:In the water, When the products be put into the water at 25℃ from the water at 50℃, Thermal time constant is the time that cost by the resistance becoming to be the value at34.2℃.

4.3Dissipation Constant(δ)

requirement:3mw/℃,3mW/℃(min, in air)

test method(The product will be join with the following circuit at 25±0.5℃ in still air.

4.4 Max.rated power

requirement:P≈275mw

calculating method:P≈δ×(80℃－25℃)

80℃ is the maximum temperature that the product is heat by itself.
