The recommended land pattern for the 1945R-20J is a rectangular pad with a minimum size of 50 mils x 30 mils, with a non-solder mask defined (NSMD) pad to ensure proper solder flow and to prevent solder from flowing onto the component body.
To handle the 1945R-20J's sensitivity to moisture, it is recommended to store the components in a dry environment (less than 20% relative humidity) and to bake the components at 125°C for 24 hours before reflow soldering to remove any moisture that may have been absorbed.
The maximum allowable voltage for the 1945R-20J is 50V, exceeding which may cause damage to the component or affect its performance.
The 1945R-20J is rated for operation up to 125°C, but it's recommended to derate the component's current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation.
To ensure the 1945R-20J's magnetic shielding is effective, it is recommended to keep the component at least 5 mm away from any ferromagnetic materials and to use a shielding material with a high permeability, such as mu-metal, around the component.
