PM2120-100K-RC - Bourns

PM2120-100K-RC Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  Bourns provides a recommended PCB layout and land pattern in their application notes. It's essential to follow these guidelines to ensure proper thermal management, minimize parasitic inductance, and optimize performance.
• How do I ensure the inductor's magnetic field does not interfere with nearby components?
  To minimize electromagnetic interference (EMI), keep the inductor at least 5 mm away from sensitive components. You can also use shielding techniques, such as copper tape or mu-metal shielding, to contain the magnetic field.
• What is the maximum allowable voltage stress for the PM2120-100K-RC?
  While the datasheet specifies a maximum rated voltage of 100 kHz, the inductor can withstand voltage stresses up to 1.5 times the rated voltage for short durations. However, it's essential to consult with Bourns' application engineers for specific guidance on voltage stress tolerance.
• Can I use the PM2120-100K-RC in a high-temperature environment?
  The PM2120-100K-RC is rated for operation up to 125°C. However, derating may be necessary for temperatures above 85°C. Consult Bourns' application notes for temperature derating guidelines and ensure proper thermal management to prevent overheating.
• How do I select the correct inductor value for my specific application?
  To select the correct inductor value, consider factors such as the target resonant frequency, desired impedance, and power handling requirements. Bourns provides inductor selection guides and application notes to help with this process.
