type ths series tyco are the leading european supplier of standard and custom designed aluminium housed resistors for general-purpose use, power supplies, power generation and the traction industry. the ths is a range of extremely stable, high quality wire wound resistors capable of dissipating high power in a limited space with relatively low surface temperature. the power is rapidly dissipated as heat through the aluminium housing to a specified heatsink. the resistors are made from quality materials for optimum reliability and stability. tyco can test resistors to conform to relevant international, mil or customer specifications. key features established product with proven reliability ? leading the way with over 50 years of design and manufacturing experience 10 watts to 75 watts versatile product ? bench mark in every industry applications braking resistor balancing resistor capacitor charging & discharging crowbar filter electrical machinery general use available through distribution characteristics - electrical long term stability: for improvements in long-term stability, resistors must be derated as follows; for 50% of stated r maximum dissipation must not exceed 70% of rating; for 25% of stated r maximum, dissipation must not exceed 50% of rating insulation resistance: dry: 10,000m? minimum. after moisture test: 1000m? minimum. heat dissipation: although the use of proprietary heat sinks with lower thermal resistance is acceptable, up rating is not recommended. the use of proprietary heat sink compound to improve thermal conductivity is recommended for optimum performance of all sizes specification: temperature coefficient below 100r, 50ppm/c temperature coefficient above 100r, 30ppm/c tolerance, 5% standard characteristics - electrical ths - 10 watts to 75 watts ths10 ths15 ths25 ths50 ths75 dissipation @ 25c with heatsink (watts): 10 15 25 50 75 without heatsink: 5.5 8 12.5 20 40 ohmic value min (ohms): r01 r01 r01 r01 r05 max: 10k 15k 36k 50k 50k max. working voltage (dc or acrms) volts: 160 265 550 1250 1400 dielectric strength (ac peak) volts: 1400 1400 2500 2500 5000 stability (% resistance change, 1000 hours) (%): 11112 standard heatsink - area (mm 2 ): 41500 41500 53500 53500 99500 thickness (mm): 11113 number of mounting holes: 2 hole 2 hole 2 hole 2 hole 4 hole product specifications - ths10 - ths75 l 4.0 5.0 type l ths10, 15 7 ths25, 50 10 ths75 8 r n j m l h dimensions - ths10 - ths50 p u t 2 x mounting hole ths10 - 2.4mm ths15 - 2.4mm ths25 - 3.3mm ths50 - 3.3mm type h0.3 j0.3 l max m max n max p max r min t0.5 u max ths10 11.3 12.4 17.0 30.0 17.0 9.0 1.9 3.4 2.5 ths15 14.3 15.9 21.0 36.5 21.0 11.0 1.9 5.2 3.2 ths25 18.3 19.8 29.0 51.8 28.0 15.0 2.8 7.2 3.2 ths50 39.7 21.4 51.0 72.5 30.0 17.0 2.8 7.9 3.2 literature no. 1773277 issued: 03-08 dimensions are shown for reference purposes only. dimensions are in millimetres unless otherwise specified. specifications subject to change. tycoelectronics.com passives.tycoelectronics.com aluminium housed power resistors type ths series
