THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 PTC Thermistors, Mini Chips for Over-Temperature Protection Note (1) Max operating temperature range is Tn +15 °C, indicated value is for Tn = 150 °C. FEATURES • Well-defined protection temperature levels • Fast reaction time (< 6 s in still air) • Accurate resistance for ease of circuit design • Excellent long term behavior (< 1 °C or 5 % after 1000 h at Tn +15 °C) • Wide range of protection temperatures (70 °C to 170 °C) • Small size and rugged • Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 APPLICATIONS Over-temperature protection and control in: • Industrial electronics • Power supplies • Motor protection DESCRIPTION These directly heated thermistors have a positive temperature coefficient and are primarily intended for sensing. MOUNTING For clamping, reflow or hand soldering. Not intended for ultrasonic soldering or for spot welding or bonding. All standard solder alloys with low activated halogen-free fluxes are acceptable. PACKAGING PTC thermistor chips are vacuum packed in 5000 pieces.
