| The TFS Series has been specifically developed to absorb large amounts of energy by efficient use of its compact mass. Ideal for medical surge protection applications, these thick film reisistors offer noninductive performance in an axial package. Uses include power supply conversion, electron microscopes, X-ray systems, highresolution CRT displays, and geophysical instrument related products. SPECIFICATIONS Material Resistive Element: Thick Film Encapsulation: Screen Printed Glass Electrical Resistance Value: 100 up to 100K Temperature Coefficient: 100ppm/C Tolerance: 1%, 2%, 5%, 10% Operating Temperature: -55C to +200C Test: VDE 0750 (Pulse Duration 10 msec) Surge Capable Thick Film Non Inductive C A B TFS Series 0.50mm H E FEATURES * Appropriate for medical surge protection applications * Ideal to replace standard carbon composition resistors * Custom dimensions, values, tolerances and characteristics available * For energy rating information, visit www.ohmite.com Type TFSA TFSB TFSC TFSD TFSE TFSF 0.25mm U (KV) 3 3.5 4 7 7 11 Energy* (J) 6 9 11 33 44 55 Power (W) 0.5 0.5 0.75 1 1.5 2 Dimensions (mm) B C H 5.5 10 0.7 5.5 10 0.7 5.5 10 0.7 8 10 0.9 10.5 10 0.9 10.5 10 0.9 A 9 11 13 21 21 26 E 1.1 1.1 1.1 1.3 1.3 1.3 MAXIMUM INDIVIDUAL PULSE RATING 1000 Energy Rating % *Published energy rating is for 10ms pulse.

Always verify designs with pulse and surge conditions through thorough testing of the design at maximum operating temperature and maximum pulse loading (or some margin above maximum pulse loading). * Damage to the resistor by excessive pulse loading is generally indicated by an increasing resistance of the resistor. * Energy ratings are based on single pulses (at least 1 minute between pulses). * For multiple pulse applications the energy pulse rating should be reduced and the average power should not exceed the nominal power rating of the selected model. 5% TFSB470RJE TFSE470RJE 5% TFSA680RJE TFSC680RJE TFSE680RJE TFSF680RJE 5% TFSB750RJE TFSD750RJE TFSF750RJE 1% TFSA1K00FE 5% TFSA1K00JE TFSB1K00JE TFSC1K00JE TFSD1K00JE TFSE1K00JE TFSF1K00JE 5% 1% 5% 1% 5% 1% 5% 5% 1% 5% TFSA1K50JE TFSA2K20FE TFSA4K70FE TFSA4K70JE TFSA4K99FE TFSA75K0JE TFSC1K50JE TFSD1K50JE TFSB2K70JE TFSC4K70JE TFSD4K70JE TFSE2K70JE TFSF1K50JE TFSB6K80JE TFSE6K80JE TFSA10K0FE TFSA10K0JE TFSB10K0JE TFSC10K0JE TFSD10K0JE TFSF10K0JE Our friendly Customer Service team can be reached at 866-9-OHMITE 5% TFSF16K0JE 1% TFSA20K0FE TFSF20K0JE 5% TFSB20K0JE TFSD20K0JE 1% TFSA22K0FE 5% TFSA27K0JE TFSC27K0JE TFSE27K0JE 1% TFSA47K0FE 5% TFSA50K0JE TFSF51K0JE 5% TFSB51K0JE TFSC51K0JE TFSD51K0JE 5% TFSE75K0JE TFSF100KJE 100,000 1% TFSA100KFE 100,000 5% TFSB100KJE TFSC100KJE TFSD100KJE Check product availability at www.ohmite.com Ohmite Mfg.
