B551SE-2T Frequently Asked Questions (FAQ)
-
The B551SE-2T can handle surge currents up to 100A for 1 cycle (16.7ms) without damage.
-
To ensure fast turn-off, a pull-down resistor (e.g., 1kΩ) should be connected between the input pin and ground to quickly discharge the internal capacitance.
-
A heat sink with a thermal resistance of 10°C/W or lower is recommended. The PCB layout should ensure good thermal conduction and minimize thermal resistance. A minimum of 1 oz copper thickness is recommended.
-
Yes, the B551SE-2T is designed to withstand high vibrations. However, it's essential to ensure the relay is properly mounted and secured to prevent damage or malfunction.
-
To minimize EMI, use a shielded cable for the input signal, and ensure the relay is mounted in a metal enclosure with good electromagnetic shielding.
