The recommended land pattern for ER1641-102KR is a rectangular pad with a size of 4.5mm x 2.5mm, with a non-solder mask defined (NSMD) pad and a 0.5mm keep-out area around the pad.
While the ER1641-102KR is rated for operation up to 125°C, it's essential to derate the inductor's current rating and consider the self-heating effect when operating in high-temperature environments. Consult with API Delevan or a thermal expert for specific guidance.
The ER1641-102KR has a shielded construction, which reduces electromagnetic interference (EMI). However, it's still important to follow proper PCB layout and design practices to minimize EMI and ensure optimal performance.
The ER1641-102KR has a DC bias tolerance of up to 1.2A, but it's essential to consider the inductor's saturation characteristics and ensure that the DC bias does not exceed the specified maximum current rating.
While the ER1641-102KR is designed for high-frequency applications, its performance may degrade above 10MHz. Consult with API Delevan or a high-frequency expert for specific guidance on using this inductor in high-frequency circuits.
