Recommended measuring currents are 1mA for 100 and 0.1mA for 500 or 1k. Precautions for Use SDT310SDT310NSDT310MT 1mA SDT310 It is difficult to solder SDT310, SDT310N and SDT310MT because of using heat-resistant leads. Make use of welding to connect the leads wire. When an operating current is 1mA or more, calculate a rise in temperature by self-heating to confirm an error. If SDT310 series is used by being molded or placed in a metal protection tube filled with resin, the resistance value may occasionally vary slightly depending on the resin used.

When calculating a resistance value of 105, read the value in the column where 100 in the vertical axis and 5 in the horizontal axis cross. The value will be 140.40. The value for 500at 0 will be the value obtained by multiplying the resistance value in this table by 5. Similarly, the value for 1K at 0 will be the value obtained by multiplying the resistance value by 10. www.koanet.co.jp
