Coiltronics recommends a pad layout with a diameter of 0.125 inches (3.18 mm) and a spacing of 0.05 inches (1.27 mm) between pads. A larger pad size can be used for improved solderability.
The DR127-470-R is rated for operation up to 125°C. However, the inductor's impedance and inductance may vary by ±15% at temperatures above 85°C. Consult Coiltronics for custom high-temperature designs.
Coiltronics recommends a soldering profile with a peak temperature of 240°C (464°F) and a dwell time of 3-5 seconds. Avoid exceeding 260°C (500°F) to prevent damage to the inductor.
Yes, the DR127-470-R is designed to withstand vibrations up to 10 G's. However, it's essential to ensure proper PCB mounting and secure the inductor to prevent movement during vibration.
The SRF of the DR127-470-R is approximately 250 MHz. This value may vary depending on the specific application and PCB layout.
