Description:The resistors are constructed in a high grade ceramic body (aluminum oxide).
Internal metal electrodes are added at each end and connected by a resistive paste
that is applied to the top surface of the substrate. The composition of the paste is
adjusted to give the approximate resistance required and the value is trimmed to
within tolerance by laser cutting of this resistive layer.
The resistive layer is covered with a protective coat. Finally, the two external
end terminations are added. For ease of
The recommended land pattern for the MCWR06X1871FTL can be found in the IPC-7351 standard or in the manufacturer's application notes. It typically includes a rectangular pad with a size of around 1.5mm x 0.8mm, with a solder mask clearance of 0.1mm.
To handle thermal considerations, ensure that the PCB design includes a thermal relief pattern around the component's pads, and consider using thermal vias to dissipate heat. Additionally, ensure that the component is placed in a location with good airflow and minimal thermal obstruction.
The recommended soldering profile for the MCWR06X1871FTL is a standard reflow profile with a peak temperature of 260°C, a dwell time of 30-60 seconds, and a ramp rate of 1-3°C/second. However, it's recommended to consult the manufacturer's application notes or soldering guidelines for specific recommendations.
To ensure reliability in high-vibration or high-shock environments, consider using a component with a higher vibration rating, such as 20G or 30G. Additionally, ensure that the PCB design includes adequate mechanical support and strain relief for the component, and consider using underfill or potting compounds to enhance mechanical stability.
The recommended storage and handling procedures for the MCWR06X1871FTL include storing the components in their original packaging, away from direct sunlight and moisture, and handling them with anti-static wrist straps or mats to prevent ESD damage.
