(for a smaller package size and more values, see our ttwb series.) applications include impedance matching, voltage or current transformation, dc isolation, balanced/unbal- anced mixing, matching, power splitting, coupling, and signal inversion. custom wide band transformers with special combina- tions of impedance ratio, insertion loss, frequency re- sponse, and current handling are also available. pins 1-3 pins 6-4 part number 1 part number 1 ? i dc max frequency l min dcr max l min dcr max configuration (through-hole) (surface mount) ratio (ma) (mhz) ( h) (ohms) ( h) (ohms) wb1010-pc wb1010-sm 1:1 250 .005-100 780 .320 780 .320 wb1010-1-pc wb1010-1-sm 1:1 250 .04-175 95 .200 95 .200 wb1015-pc wb1015-sm 1:1.5 250 .1-150 80 .145 51 .130 wb1040-pc wb1040-sm 1:4 250 .2-300 95 .160 25 .115 wb2010-pc wb2010-sm 1:1 250 .005-100 780 .320 780 .320 wb2010-1-pc wb2010-1-sm 1:1 250 .04-175 95 .200 95 .200 wb2040-pc WB2040-SM 1:4 250 .2-300 95 .160 25 .115 wb3010-pc wb3010-sm 1:1 250 .005-100 780 .320 780 .320 wb3010-1-pc wb3010-1-sm 1:1 250 .04-175 95 .200 95 .200 wb3015-pc wb3015-sm 1:1.5 250 .1-150 80 .145 51 .130 wb3040-pc wb3040-sm 1:4 250 .2-300 95 .160 25 .115 specifications subject to change without notice. document 116-1 revised 01/29/01
