Frequently Asked Questions
What are the main applications for DR type inductors?
DR type inductors are commonly used in power supplies, DC-DC converters, and noise filtering applications due to their compact size and high efficiency.
Can the inductance and DCR be customized?
Yes, custom designs are available for both Inductance and DC Resistance (Max) to meet your specific circuit requirements.
What material is used for the core?
These inductors utilize high-quality PC40 series ferrite, which is optimized for power applications and low losses.
What is the standard switching frequency for these specifications?
The standard design and testing specifications are based on a switching frequency of 100KHz.
How do I interpret the size dimensions in the table?
The dimensions refer to the Max diameter (CA), Height (B), and Lead spacing/length (C, CD, E) as illustrated in the technical drawing.
Are these inductors compatible with automated assembly?
Yes, the radial lead design is suitable for through-hole mounting, and the standardized dimensions facilitate efficient PCB assembly.
