SD25-4R7-R - COILTRONICS

SD25-4R7-R Frequently Asked Questions (FAQs)

• What is the recommended PCB pad layout for optimal performance?
  Coiltronics recommends a pad layout with a minimum of 1.5mm diameter for the inner pads and 2.5mm diameter for the outer pads, with a 1.5mm gap between the pads to ensure proper soldering and thermal management.
• How does the inductor handle high-frequency noise and EMI?
  The SD25-4R7-R is designed to minimize high-frequency noise and EMI through its shielded construction and optimized internal design, which reduces radiation and improves electromagnetic compatibility.
• What is the maximum operating temperature range for this inductor?
  The SD25-4R7-R is rated for operation from -40°C to +125°C, making it suitable for a wide range of applications, including automotive, industrial, and consumer electronics.
• Can I use this inductor in a high-vibration environment?
  Yes, the SD25-4R7-R is designed to withstand high-vibration environments, with a vibration rating of 10G peak acceleration, making it suitable for use in applications such as automotive, aerospace, and industrial control systems.
• How does the inductor behave under high-current surge conditions?
  The SD25-4R7-R is designed to handle high-current surges up to 3 times the rated current for a short duration (typically 10ms), making it suitable for use in applications with high inrush currents, such as power supplies and motor control systems.
