R19E3.pdf 01.10.26 Standard Type POSISTORr Notice 1 ■ Notice(Soldering and Mounting) PTWSB Series 1. Design aseembling position of "POSISTOR" with considering heatproof. 2. Make the heat resistance as small as possible, between the "POSISTOR" and the place it is connected. Do not use an insulating sheet which is poor in heat transmission. Install the "POSISTOR" in the flat surface to maximize the function. Application of heat resisting grease (e.g.siliconegrease), into interfaces of "POSISTOR" substrate - insulator - material to be heated, will permit effective heat transmission. 3. When more than one "POSISTOR" are used, be sure to connect them in parallel. If "POSISTOR" are connected in series, they don't operate normally. 4. When lead wires are connected to "POSISTOR", use rosin type flux which includes less than 0.2wt% of chlorine. Also pay attention to connecting method in order to prevent "POSISTOR" from invasion of flux, and to heatproof of connecting materials (ex:solder etc). 5. This product generates heat at operation, and direct touch to the surface can hart human finger or skin. Pay attention at the installation to prevent direct touch from outside. ■ Notice(Soldering and Mounting) PTWTA Series 1. Heat resistance of the mounting part must be considered in designing. 2. Four mounting holes 1.0 to 1.5 mm in depth and 5 to 5.5 mm in diameter are required on the heated part contacting "POSISTOR". 3. Apply power with "POSISTOR" mounted into the part heated. If power is applied to "POSISTOR" alone, the alumina case may be broken. 4. When more than one "POSISTOR" are used, be sure to connect them in parallel. If "POSISTOR" are connected in series, they don't operate normally. 5. When lead wires are connected to "POSISTOR", spot welding method should be adopted. Recommendable material of lead wires is Nickel. 6. This product generates heat at operation, and direct touch to the surface can hart human finger or skin. Pay attention at the installation to prevent direct touch from outside. ■ Notice(Rating) Do not apply voltage the maximum voltage. Because their characteristics might be worse and PTC element may be destroyed. 5 Please read CAUTION and Notice in this catalog for safety. This catalog has only typical specifications.
