RFC1010B-474KE - COILCRAFT

RFC1010B-474KE Frequently Asked Questions (FAQs)

• What is the recommended land pattern for RFC1010B-474KE?
  Coilcraft provides a recommended land pattern for the RFC1010B-474KE in their documentation, which can be found on their website. The recommended land pattern is designed to ensure optimal performance and reliability of the inductor.
• Can I use RFC1010B-474KE in a high-temperature environment?
  The RFC1010B-474KE is rated for operation up to 125°C, but it's recommended to derate the current rating at higher temperatures. Coilcraft provides a temperature derating curve in their documentation, which can be used to determine the maximum current rating at a given temperature.
• How do I handle the RFC1010B-474KE during PCB assembly to prevent damage?
  To prevent damage during PCB assembly, it's recommended to handle the RFC1010B-474KE by the body of the inductor, rather than the leads. This will help prevent mechanical stress on the leads, which can cause damage or failure. Additionally, it's recommended to use a vacuum pickup or tweezers to handle the component, rather than touching it with bare hands.
• What is the equivalent series resistance (ESR) of the RFC1010B-474KE?
  The ESR of the RFC1010B-474KE is not explicitly stated in the datasheet, but it can be calculated using the impedance vs. frequency graph provided in the datasheet. Alternatively, Coilcraft provides an ESR calculator tool on their website, which can be used to estimate the ESR of the inductor.
• Can I use RFC1010B-474KE in a parallel configuration to increase the current rating?
  Yes, the RFC1010B-474KE can be used in a parallel configuration to increase the current rating. However, it's important to ensure that the inductors are properly matched and that the PCB layout is designed to minimize parasitic inductance and resistance. Coilcraft provides guidelines for parallel configuration in their documentation.
