SMR-8.000-B Frequently Asked Questions (FAQs)
-
Raltron recommends following the IPC-7351B standard for land pattern design and to keep the PCB layout as symmetrical as possible to minimize parasitic effects. A minimum of 2-layer PCB with a solid ground plane is recommended.
-
Impedance matching is critical for optimal performance. Raltron recommends using a 50-ohm transmission line and ensuring that the PCB layout and component selection are designed to maintain a 50-ohm impedance throughout the signal path.
-
While the datasheet specifies an operating temperature range of -40°C to +85°C, Raltron recommends derating the device for reliable performance above +70°C. Consult with Raltron's application engineers for specific guidance on temperature derating.
-
Raltron recommends following proper ESD handling procedures during assembly and installation. Additionally, consider adding ESD protection devices, such as TVS diodes or ESD suppressors, in the circuit design to protect the SMR-8.000-B from electrostatic discharge.
-
Raltron recommends following the IPC-J-STD-020D standard for soldering profile. A peak temperature of 260°C (500°F) and a dwell time of 10-30 seconds are recommended. Consult with Raltron's application engineers for specific guidance on soldering profiles.
