| MPR24 Vishay BCcomponents Ultra Precision Leaded Resistors FEATURES * Ultra high precision resistors * Ultra high stability * Ultra low temperature coefficient. APPLICATIONS * Test and measurement * Telecom. DESCRIPTION A homogeneous film of metal alloy is deposited on a high grade ceramic body. After a helical groove has been cut in the resistive layer, tinned connecting wires of electrolytic copper are welded to the end-caps. The resistors are coated with lacquer which provides electrical, mechanical, and climatic protection.

The following table contains only the most important tests. For the full test schedule refer to the documents listed above. The testing also covers most of the requirements specified by EIA/IS-703 and JIS-C-5202. The tests are carried out in accordance with IEC 60 068 and under standard atmospheric conditions in accordance with IEC 60068-1, 5.3. Climatic category LCT/UCT/56 (rated temperature range: Lower Category Temperature, Upper Category Temperature; damp heat, long term, 56 days) is valid. Unless otherwise specified the following values apply: Temperature: 15 C to 35 C Relative humidity: 45 % to 75 % Air pressure: 86 kPa to 106 kPa (860 mbar to 1 060 mbar). For testing the components are mounted on a test board in accordance with IEC 60115-1, 4.31 unless otherwise specified. In the Test Procedures and Requirements table only the tests and requirements are listed with reference to the relevant clauses of IEC 60115-1 and IEC 60068-2; a short description of the test procedure is also given. www.vishay.com 4 For technical questions contact: ff3cresistors@vishay.com Document Number: 28727 Revision: 08-Mar-04 MPR24 Ultra Precision Leaded Resistors Vishay BCcomponents TEST PROCEDURES AND REQUIREMENTS IEC 60115-1 CLAUSE IEC 60068-2 TEST METHOD TEST PROCEDURE REQUIREMENTS PERMISSIBLE CHANGE (R/R) Stability for product types: MPR24 4.5 4.8.4.2 - - resistance temperature coefficient - at 20 / 70 / 20 C at 20 / LCT / 20 C and 20 / UCT / 20 C U = P 70 x R or U = Umax; 1.5 h on; 0.5 h off 70 C; 2000 h 4.24 78 (Cab) damp heat, steady state climatic sequence: 2 (Ba) 30 (Db) dry heat damp heat, cyclic cold low air pressure damp heat, cyclic short time overload rapid change of temperature component solvent resistance resistance to soldering heat 125 C; 16 h 55 C; 24 h; 90 to 100 % RH; 1 cycle -55 C; 2 h 8.5 kPa; 2 h; 15 to 35 C 55 C; 5 days; 95 to 100 % RH; 5 cycles room temperature; U = 2.5 x P 70 x R or U = 2 x Umax; 5 s 30 minutes at LCT and 30 minutes at UCT; 5 cycles isopropyl alcohol +23 C; toothbrush method unmounted components; (260 5) C; (10 1) s + 235 C; 2 s solder bath method 6 h; 10 to 2 000 Hz 1.5 mm or 196 m/s2 tensile, bending and torsion Urms = 100 V; 60 s IEC 60 195: R 100 k R > 100 k (0.05 % + 0.01 ) no visible damage (0.01 % + 0.01 ) no visible damage (0.01 % + 0.01 ) no visible damage marking legible; no visible damage (0.01 % + 0.01 ) no visible damage (40 2) C; 56 days; (93 3) % RH (0.05 % + 0.01 ) (0.05 % + 0.01 ) 24 to 100 k 0.5 %; 0.25 %; 0.1 %; 0.05 %; 0.02 %; 0.01 % 4.99 to < 24 ; > 100 k to 1 M 0.5 %; 0.25 %; 0.1 % 25 ppm/K; 15 ppm/K; 10 ppm/K; 05 ppm/K 25 ppm/K 4.25.1 - endurance at 70 C 4.23 4.23.2 4.23.3 4.23.4 4.23.5 4.23.6 1 (Aa) 13 (M) 30 (Db) 4.13 - 4.19 14 (Na) 4.29 45 (XA) 4.18.2 20 (Tb) 4.17 4.22 4.16 20 (Ta) 6 (B4) 21 (Ua1) 21 (Ub) 21 (Uc) - - solderability vibration robustness of terminations voltage proof noise good tinning ( 95 % coverage); (0.01 % + 0.01 ); no visible damage (0.01 % + 0.01 ); no visible damage no flashover or breakdown max. 0.25 V/V max. 0.5 V/V www.vishay.com 5 4.7 4.12 Document Number: 28727 Revision: 08-Mar-04 For technical questions contact: ff3cresistors@vishay.com MPR24 Ultra Precision Leaded Resistors Vishay BCcomponents ORDERING INFORMATION Components may be ordered by using either a simple clear text ordering code, see "Type Description and Ordering Code" or Vishay BCcomponents' unique 12NC. Numeric Ordering Code (12NC) * The resistors have a 12-digit ordering code starting with 2322 14. * The subsequent 3 digits indicate the resistor type, specification and packaging; see the 12NC Ordering Code table. * The remaining 3 digits indicate the resistance value. The number is available upon request and is fixed by the supplier.
