Bourns recommends a symmetrical layout with a central pad for the sensor, and a 1.5mm keep-out zone around the device. A recommended land pattern is available in the Bourns application note AN16.
The 3540S-1-501L is rated for operation up to 125°C, but its accuracy may degrade above 100°C. For high-temperature applications, consider using a thermally compensated version or consulting with Bourns' application engineers.
Bourns recommends a two-point calibration procedure using a calibrated magnet and a digital multimeter. The procedure is outlined in the 3540S-1-501L datasheet, and additional guidance is available from Bourns' technical support team.
The 3540S-1-501L is designed to reject external magnetic interference, but it's not completely immune. To minimize interference, use a mu-metal shield or a ferrite bead on the PCB, and ensure proper PCB layout and grounding.
The typical lead time for the 3540S-1-501L is 8-12 weeks, and the minimum order quantity (MOQ) is 1,000 pieces. However, these can vary depending on the region and distribution channel. Contact a Bourns authorized distributor or representative for the most up-to-date information.
