CD123D-B140LR - Bourns

CD123D-B140LR 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 note AN164, which can be found on their website. Following this layout ensures optimal performance and minimizes parasitic effects.
• How does the CD123D-B140LR behave in high-temperature environments?
  While the datasheet specifies an operating temperature range of -40°C to 125°C, Bourns recommends derating the current rating by 1.5% per degree Celsius above 85°C to ensure reliable operation. Consult Bourns' application notes for more information on high-temperature operation.
• What is the maximum surge current rating for the CD123D-B140LR?
  Although not explicitly stated in the datasheet, Bourns specifies a surge current rating of 100 A for 10 ms in their application note AN164. This rating is based on the device's internal construction and materials.
• Can the CD123D-B140LR be used in high-frequency applications?
  While the CD123D-B140LR is primarily designed for low-frequency applications, it can be used in high-frequency applications up to 100 kHz with some limitations. Consult Bourns' application notes for guidance on high-frequency operation and potential derating.
• What is the recommended storage and handling procedure for the CD123D-B140LR?
  Bourns recommends storing the CD123D-B140LR in a dry, cool place, away from direct sunlight and moisture. Handling should be done with anti-static precautions, such as using an anti-static wrist strap or mat, to prevent damage from electrostatic discharge.
