Additional Details

The 0402HP-8N2XGEW is typically constructed using ceramic materials and precision winding techniques to achieve its high performance characteristics. The operating temperature range is generally from -40°C to +125°C. The self-resonant frequency (SRF) should be significantly higher than the operating frequency to minimize parasitic effects. The DC resistance (DCR) is also an important parameter to consider as it impacts power loss. Proper soldering techniques and PCB layout practices are crucial for optimal performance and reliability. Always refer to the manufacturer's datasheet for detailed specifications, including inductance tolerance, Q factor at specific frequencies, SRF, DCR, and current rating. This inductor is an essential component in modern RF circuit design, enabling high performance in a small form factor.
