THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 30 V to 60 V PTC Thermistors for Overload Protection QUALITY UL approved PTCs are guaranteed to withstand severe test programs and have factory audited follow-up programs. Major UL qualification tests are long-life (6000 cycles) electrical cycle tests at trip-current, long-life stability storage tests (3000 h at 250 °C), damp heat and water immersion tests and over-voltage tests up to 200 % of rated voltage. UL approved PTCs are guaranteed to withstand severe test programs • Long-life cycle tests (over 5000 trip cycles) • Long-life storage tests (3000 h at 250 °C) • Electrical cycle tests at low ambient temperatures (-40 °C or 0 °C) • Damp-heat and water immersion tests • Overvoltage tests at up to 200 % of rated voltage FEATURES • Wide range of trip and non-trip currents: From 94 mA up to 2 A for the trip current • Small ratio between trip and non-trip currents (It/Int = 1.5 at 25 °C) • High maximum overload current (up to 23 A) • Leaded parts withstand mechanical stresses and vibration • UL file E148885 according to XGPU standard UL1434 • Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 APPLICATIONS Overload (current, voltage, temperature) protection in: • Industrial electronics • Consumer electronics • Electronic data processing DESCRIPTION These directly heated ceramic-based thermistors have a positive temperature coefficient and are primarily intended for overload protection. They consist of a ceramic pellet soldered between two tinned CCS wires and coated with a UL 94 V-0 high temperature hard silicone lacquer. Bare metalized pellets are available on request. MOUNTING PTC thermistors can be mounted by wave, reflow, or hand-soldering. Current levels have been determined according IEC 60738 conditions. Different ways of mounting or connecting the thermistors can influence their thermal and electrical behavior. Standard operation is in air, any potting or encapsulation of PTC thermistors is not recommended and will change its operating characteristics. Typical Soldering 235 °C; duration: 5 s (lead (Pb)-bearing) 245 °C, duration: 5 s (lead (Pb)-free) Resistance to Soldering Heat 260 °C, duration: 10 s max. MARKING Only the gray lacquered thermistors with a diameter of 8.5 mm to 20.5 mm are marked with BC, R25 value (example 1R9) on one side and Int, Vmax. on the other side. QUICK REFERENCE DATA PARAMETER VALUE UNIT Maximum voltage (DC or AC) 30 to 60 V Maximum holding current (Int) 0.094 to 2 A Resistance at 25 °C ( R25) 0.3 to 50 Ω Tolerance on R25 value 20 % Maximum overload current Iol 0.8 to 23 A Switching temperature 135 to 145 °C Operating temperature range at max. voltage -40 to +85 °C Storage temperature -40 to +150 °C |
