(2) dc resistance is measured by digital multimeter tr6871 (advantest) or equivalent. (3) maximum allowable dc current is that which causes a 30% inductance reduction from the initial value, or coil temperature to rise by 40 c, whichever is smaller. (reference ambient temperature 20 c). toko america, inc. 1250 feehanville drive, mount prospect, illinois 60056 tel: (847) 297-0070 fax: (847) 699-7864 web: http:// www.tokoam.com the information furnished by toko, inc. is believed to be accurate and reliable. however, toko reserves the right to make chan ges or improvements in the design, specification or manufacture of its products without further notice. toko does not assume any liability arising from the application or use of any product o r circuit described herein, nor for any infringements of patents or other rights of third parties which may result from the use of its products. no license is granted by implication or otherw ise under any patent or patent rights of toko, inc. 0.95 0.80 0.79 0.78 0.57 0.46 0.40 0.37 0.30 0.19
