The recommended PCB layout and land pattern can be found in the CIT Relay & Switch application note AN-105, which provides guidelines for optimal relay mounting and PCB design.
To ensure reliable switching performance in high-vibration environments, it is recommended to use a relay socket or a relay with a built-in stabilizer, such as the CT11028.0F160-S, which is designed to reduce the effects of vibration and shock.
The maximum allowable voltage drop across the relay contacts is typically 100 mV to 200 mV, depending on the specific application and requirements. It is recommended to consult with CIT Relay & Switch or a qualified engineer to determine the suitable voltage drop for a specific design.
The CT11028.0F160 is rated for operation up to 85°C (185°F), but it can be used in high-temperature environments with derating. Consult with CIT Relay & Switch or a qualified engineer to determine the suitable operating temperature and derating factors for a specific application.
The recommended coil suppression method is to use a diode and resistor in parallel across the coil, also known as a snubber circuit. This helps to reduce EMI and voltage spikes when the relay is switched off.
