MA5281-BLD Frequently Asked Questions (FAQs)

Coilcraft recommends a land pattern with a pad size of 2.5 mm x 1.5 mm, with a non-solder mask defined (NSMD) pad and a 0.5 mm x 0.5 mm thermal pad in the center.
To minimize the impact of the SRF, use the inductor in a circuit with a resonant frequency below the SRF, or add a capacitor in parallel to the inductor to create a low-pass filter, which can help reduce the Q factor and minimize resonance.
The MA5281-BLD has an operating temperature range of -40°C to +125°C, with a maximum storage temperature range of -40°C to +150°C.
Use a soldering profile with a peak temperature of 240°C to 250°C, and ensure the soldering time is within 3-5 seconds. Also, use a solder with a melting point above 217°C to prevent thermal damage to the inductor.
Yes, the MA5281-BLD is designed to withstand high-vibration and high-shock environments, with a vibration rating of 10-2000 Hz, 10 G peak acceleration, and a shock rating of 100 G, 11 ms duration.
