DESCRIPTION
The resistors are constructed in a high grade ceramic body (aluminum oxide). external metal electrodes are added at both end and connected by a resistive layer that is applied to the metallised rods. The composition of the resistive layer is adjusted to give the approximate resistance required and the value is trimmed to nominated value within tolerance which controlled by laser trimming of this resistive layer. The resistive film is covered by epoxy molding compound designed for electrical, mechanical and climatic protection,and color code rings designate the resistance value. Finally, the two external end terminations are added nickel plating and tin. For environmental soldering issue, the outer layer of these end terminations is a Lead-free solder . Fig 1.

Page 4 of 11 ASC_MMxxB&C AUG - 2018 FUNCTIONAL DESCRIPTION PRODUCT CHARACTERIZATION Standard values of nominal resistance are taken from the E192 series for resistors with a tolerance of ±1%, DERATING The power that the resistor can dissipate depends on the operating temperature; see Fig.2 MOUNTING Due to their rectangular shapes and small tolerances, Surface Mountable Resistors are suitable for handling by automatic placement systems. Cylindrical placement can be on ceramic rods and printed-circuit boards (PCBs). Electrical connection to the circuit is by individual soldering condition. The end terminations guarantee a reliable contact. RECOMMEND LAND PATTERN Type 0207 0204 A (mm) 3.0 1.6 B (mm) 1.7 1.2 C (mm) 2.4 1.6 A B C
