rev. 09/16 specifcations are subject to change without notice. the device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time. users should verify actual device performance in their specifc applications. hc series breaker (thermal cutoff device) caution when using breaker (continued) handling cautions 1. since the breaker body is composed of plastic parts, do not clamp or dent with tools as this could cause a resistance increase or body damage. 2. breaker terminals are thin copper-alloy with right angle edges. handle carefully to avoid injury to fngers. handling while wearing fnger cots and using tweezers is recommended. 3. when welding breaker terminals or mounting the breaker on a cell or pcm board, be careful to avoid placing excessive stress on the breaker body and terminals. excessive stress may cause a resistance increase or body damage. please refer to the following cautions: a) do not apply more than 10 n moment to the breaker body (refer to figure 1) b) do not apply more than 1.5 cn-m twist torque to the breaker body (refer to figure 2) c) do not apply more than 20 n bending force to the breaker body (refer to figure 3) d) do not apply more than 2.0 cn-m twist torque to the breaker terminals (refer to figure 4) e) do not apply more than 2 n force to the breaker terminals (refer to figure 5) f) do not bend terminals more than 45 at root (refer to figure 6) g) do not twist terminals more than 10 with the breaker body affxed. 4. in breaker body welding, normally there is direct welding (figure 7) and series welding (figure 8). in either case, use a suitable jig so that stress will not exceed the limits stated above. 5. pull-and-detach strength of the terminal welding should be to your own specifcation. if the welding result is controlled by resistance, measurement should be made at a close point to the breaker body by dc 4-point clip method using a milliohm meter to ensure accuracy (refer to figure 9). 6. avoid putting excessive stress as shown above in 3-a) to 3-g) when the jig is used for welding/additional processing. 7. confrm the resistance value after each time an additional process is applied. rod a rod b rod a figure 1 figure 2 figure 9 figure 3 figure 4 figure 5 figure 6 figure 7 figure 8 rod b 45 45 45 45 milliohm meter due to possible updates to safety standards and other reasons, there may be changes in specifcations for this data sheet without prior notifcation. therefore, before design-in for your application, please contact us for the most up-to-date specifcations.
