Attention
This product high temperature coefficient. When measuring resistance, resistance value change Joule Heating. Therefore, measuring current shall very small order prevent resistance value from changing. (For example, when resistor used RCWV, temperature resistor rise about resistance value rise percents.) Resistance value also change ambient temperature. Resistance value measured
Recommended Land Pattern
case soldering, land width must smaller than Chip Resistor width control solder amount properly. Generally, land width should times width chip resistor. case reflow soldering, solder amount adjusted, therefore land width should times chip resistor width (W). Example

Safety Precautions
following precautions individual products. Please also refer precautions common Fixed Resistors shown page this catalog. Keep rated power ambient temperature within specified derating curve. When positioning mounting Metal Film Thermosensitive Chip Resistors (hereafter called resistors), make allowance effect heat generated through close contact between resistors neighboring components temperature rise adjacent heat-generating components. transient load (heavy load short time) like pulse expected applied, check evaluate operations resistors when installed your products before use. When applying pulses resistors, keep pulse peak within rated voltage. halogen-based other high-activity flux. Otherwise, residue impair resistors' performance and/or reliability. When soldering with soldering iron, never touch resistors' bodies with soldering iron. When using soldering iron with high temperature tip, finish soldering quickly possible (within three seconds max.). amount applied solder becomes larger, mechanical stress applied resistors increases, causing problems such cracks faulty characteristics. Avoid applying excessive amount solder. When resistors' protective coatings chipped, flawed, removed, characteristics resistors impaired. Take special care apply mechanical shock during automatic mounting cause damage during handling boards with resistors mounted. apply shock resistors pinch them with hard tool (e.g. pliers tweezers). Otherwise, resistors' protective coatings bodies chipped, affecting their performance. Avoid excessive bending printed circuit boards order protect resistors from abnormal stress. immerse resistors solvent long time. Before using solvent, carefully check effects immersion.
