CTS recommends a symmetrical PCB layout with a solid ground plane to minimize electromagnetic interference (EMI) and ensure optimal performance. A minimum of 2 oz copper thickness is recommended for the PCB.
The 204-121STR has a maximum operating temperature of 125°C. Ensure proper heat sinking and thermal management by using a heat sink with a thermal conductivity of at least 1 W/m-K and a thermal interface material with a thermal conductivity of at least 5 W/m-K.
CTS recommends a reflow soldering process with a peak temperature of 260°C and a dwell time of 20-30 seconds. Hand soldering is not recommended due to the risk of overheating the component.
CTS recommends using a secure mounting method, such as a screw or adhesive, to prevent the device from shifting or detaching during high-vibration conditions. Additionally, ensure that the PCB is properly secured to the chassis or enclosure.
The 204-121STR has a soft-start feature that ramps up the output voltage over a period of 10 ms to prevent inrush currents. During power-off, the device's output voltage decays exponentially with a time constant of 100 μs.
