Product Data Short Form Resistors BI Technologies IRC Welwyn 1 Resistors TT Electronics plc is a global electronics company. Within its resistors business unit are multiple manufacturing facilities and dedicated engineering teams providing custom solutions. BI Technologies, IRC and Welwyn are market leading brands within this group, with a 70-year track record of resistive component innovation. TT Electronics offers the full spectrum of resistor technologies and a broad standard product range, in addition to providing custom engineered solutions. Medical Application A manufacturer of portable automatic external defibrillators (AEDs) needed a compact high voltage resistor for use in the charge regulation circuit. Standard products from other sources were proving unreliable under conditions of sustained high humidity and high voltage loading. The precision and stability with time and temperature were critical as they directly impact the tight error budget for delivered energy dosage. TT Electronics engineers solved this problem with a planar resistor with optimised thick-film element design and a high integrity epoxy coating and supported the customer through their rigorous approval process. Other innovations in this area include pulse withstanding chip resistors for monitor circuit protection and a 200J energy dump resistor based on reinforced wirewound technology to enable daily self-test diagnostic cycles. Aerospace Application A designer working on an anti-ice aircraft surface heating system had to meet stringent safety requirements in the event of failure of a heating circuit. The failure mode to be mitigated was an “always on” condition, and this called for a single shot disconnection switch. TT Electronics engineers were contacted to help identify a solution, but nothing was available off the shelf. A set of potential solutions was proposed and the preferred option was a combination of self-switching resistive heater and thermal fuse. This was developed from concept into a fully qualified component within the required timescale. The compact format of the design also contributed significantly to the customer’s mass reduction target. Consumer Application Safety is becoming increasingly important in consumer products and a key aspect is protection against fire by the use of fusing line input resistors. With one component it is possible to reduce inrush current, protect against power line surges and give flameproof circuit opening under fault conditions. One company working in this area had a further need for fusing to be inaudible and invisible to the consumer. TT Electronics devised a solution using a wirewound resistor with impact absorbing coating which contains the fused element without fragmenting. Other innovations include the offer of UL1412 recognised fusing resistors. Resistors Industrial Application High-end industrial circuit breakers need to give reliable long-term performance under harsh conditions. In particular, transient surges caused by switching of inductive loads present a challenge. When a designer of industrial circuit breakers needed to modernise a design to SMT format, a through-hole wirewound protection resistor was proving hard to replace without filling a very large area with chip resistors. TT Electronics developed a solution whereby an axial part is leadformed and packed in blister tape. The resulting “ZI-form” component can be picked, placed and reflowed as an SMT part.

R = V / I Terms and Definitions Ambient Temperature Critical Resistance Isolation Voltage (Voltage Proof) LEV (Max Volts) Overload Power Rating Pulse (Surge) Series TCR Tolerance Type VCR 18 The temperature which would be adopted by the body of the resistor under application conditions except with negligible power dissipation in the resistor. The resistance value at which application of the LEV causes dissipation of the full rated power. The maximum continuous voltage which may be applied between the resistor and a conductor in contact with its insulated body. The maximum continuous voltage which may be applied across a resistor whose ohmic value is greater than the critical resistance. Power dissipation which exceeds the power rating for durations exceeding 0.1s. The maximum continuous power that may be dissipated by a resistor whose ohmic value is less than the critical resistance and at a defined maximum ambient temperature. Power dissipation which exceeds the power rating for durations less than 0.1s. A set of components with the same basic design features and performance and usually a range of sizes and ratings. Temperature Coefficient of Resistance; the maximum magnitude of reversible ohmic value change per degree centigrade due to deviation in body temperature from a reference normally of 20°C. The maximum allowable magnitude of deviation from nominal ohmic value measured at delivery and at room temperature. An individual member of a series with specified size and rating. Voltage Coefficient of Resistance; the maximum reversible reduction in ohmic value per volt due to an increase in applied voltage. 1 1.01 1.02 1.04 1.05 1.06 1.07 1.09 1.1 1.11 1.13 1.14 1.15 1.17 1.18 1.2 1.21 1.23 1.24 1.26 1.27 1.29 1.3 1.32 1.33 1.35 1.37 1.38 1.4 1.42 1.43 1.45 1.47 1.49 1.5 1.52 1.54 1.56 1.58 1.6 1.62 1.64 1.65 1.67 1.69 1.72 1.74 1.76 1.78 1.8 1.82 1.84 1.87 1.89 1.91 1.93 1.96 1.98 2 2.03 2.05 2.08 2.1 2.13 2.15 2.18 2.21 2.23 2.26 2.29 2.32 2.34 2.37 2.4 2.43 2.46 2.49 2.52 2.55 2.58 2.61 2.64 2.67 2.71 2.74 2.77 2.8 2.84 2.87 2.91 2.94 2.98 3.01 3.05 3.09 3.12 E192 3.16 3.2 3.24 3.28 3.32 3.36 3.4 3.44 3.48 3.52 3.57 3.61 3.65 3.7 3.74 3.79 3.83 3.88 3.92 3.97 4.02 4.07 4.12 4.17 4.22 4.27 4.32 4.37 4.42 4.48 4.53 4.59 4.64 4.7 4.75 4.81 4.87 4.93 4.99 5.05 5.11 5.17 5.23 5.3 5.36 5.42 5.49 5.56 5.62 5.69 5.76 5.83 5.9 5.97 6.04 6.12 6.19 6.26 6.34 6.42 6.49 6.57 6.65 6.73 6.81 6.9 6.98 7.06 7.15 7.23 7.32 7.41 7.5 7.59 7.68 7.77 7.87 7.96 8.06 8.16 8.25 8.35 8.45 8.56 8.66 8.76 8.87 8.98 9.09 9.2 9.31 9.42 9.53 9.65 9.76 9.88 10 etc… E96 1 1.02 1.05 1.07 1.1 1.13 1.15 1.18 1.21 1.24 1.27 1.3 1.33 1.37 1.4 1.43 1.47 1.5 1.54 1.58 1.62 1.65 1.69 1.74 1.78 1.82 1.87 1.91 1.96 2 2.05 2.1 2.15 2.21 2.26 2.32 2.37 2.43 2.49 2.55 2.61 2.67 2.74 2.8 2.87 2.94 3.01 3.09 3.16 3.24 3.32 3.4 3.48 3.57 3.65 3.74 3.83 3.92 4.02 4.12 4.22 4.32 4.42 4.53 4.64 4.75 4.87 4.99 5.11 5.23 5.36 5.49 5.62 5.76 5.9 6.04 6.19 6.34 6.49 6.65 6.81 6.98 7.15 7.32 7.5 7.68 7.87 8.06 8.25 8.45 8.66 8.87 9.09 9.31 9.53 9.76 10 etc… E24 1 1.1 1.2 1.3 1.5 1.6 1.8 2 2.2 2.4 2.7 3 3.3 3.6 3.9 4.3 4.7 5.1 5.6 6.2 6.8 7.5 8.2 9.1 10 etc… E12 1 1.2 1.5 1.8 2.2 2.7 3.3 3.9 4.7 5.6 6.8 8.2 10 etc… E6 1 1.5 2.2 3.3 4.7 6.8 10 etc… 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 BI Technologies IRC Welwyn www.ttelectronicsresistors.com Sales Enquiries: http://www.ttelectronicsresistors.com/sales.php General Note TT Electronics reserves the right to make changes in product specification without notice or liability.
