13 kinds of CDRH CD104R SMD power inductors 10X10X4mm, 5pcs each
The CDRH CD104R SMD power inductors are high-performance surface-mount components designed for switching power supply circuits, DC-DC converters, and RF filtering applications in compact electronic devices. These inductors are widely used by circuit design engineers, PCB manufacturers, and electronics assembly professionals who require reliable energy storage and current filtering in space-constrained applications. This assortment solves the critical problem of managing electromagnetic interference, reducing power loss, and stabilizing current flow in modern switching mode power supplies while maintaining compact footprint requirements.
Product Overview
The CDRH CD104R series represents a comprehensive range of SMD power inductors engineered with ferrite core technology and copper wire windings optimized for high-frequency operation. These 10X10X4mm form-factor inductors operate on the principle of electromagnetic induction, where alternating or varying current creates a magnetic field that opposes changes in current flow. The ferrite core material provides excellent permeability characteristics across the frequency spectrum from DC to several megahertz, enabling efficient energy storage with minimal core losses. The shielded design reduces electromagnetic radiation and cross-talk interference in densely populated PCBs, making these inductors ideal for multi-layer circuit board applications.
What distinguishes the CD104R series is the availability of 13 different inductance values in a single assortment, allowing design engineers to stock a complete range without multiple purchases. Each value comes in a 5-piece quantity, providing sufficient components for prototyping, testing, and small-batch production runs. The SMD packaging eliminates the need for manual lead forming and enables automated pick-and-place assembly on modern manufacturing lines. The compact 10X10X4mm dimensions minimize board real estate while maintaining adequate copper cross-section for current handling, typically supporting saturation currents between 2A to 8A depending on inductance value.

How to Use
When integrating CDRH CD104R inductors into your circuit design, begin by calculating the required inductance value using the formula L = (V_out x D) / (I_ripple x f_sw), where V_out is output voltage, D is duty cycle, I_ripple is acceptable current ripple, and f_sw is switching frequency. Select the appropriate inductance value from the 13-piece assortment based on your power conversion topology. For buck converters, place the inductor between the switch output and the load; for boost converters, position it between the input source and the switching node. Ensure adequate PCB trace width to handle the calculated saturation current, typically using 2-4 ounce copper for currents above 5A.
During PCB layout, maintain minimum spacing of 5mm between the inductor and sensitive analog circuits to prevent magnetic field coupling. Solder the SMD inductor using standard reflow processes with peak temperatures between 240-260 degrees Celsius for 10-30 seconds. Verify inductance values using an LCR meter before final assembly, as ferrite cores can exhibit slight manufacturing tolerances. Add bypass capacitors in parallel with the inductor output to filter high-frequency ripple and protect downstream circuits. For high-current applications above 5A, consider thermal management by increasing copper area around the inductor pads to dissipate resistive losses as heat.
Frequently Asked Questions
What inductance values are included in the 13-piece assortment?
The CDRH CD104R assortment typically includes 13 standard inductance values: 1uH, 1.5uH, 2.2uH, 3.3uH, 4.7uH, 6.8uH, 10uH, 15uH, 22uH, 33uH, 47uH, 68uH, and 100uH. Each value comes with 5 pieces, providing 65 total inductors. These values cover the most common requirements in switching power supply design, RF filtering, and EMI suppression circuits.
Can these inductors handle high-frequency switching applications above 50MHz?
Yes, the CDRH CD104R series is rated for operation up to 100MHz, making it suitable for high-frequency switching applications. However, inductance values may decrease slightly at higher frequencies due to core losses and skin effect in the copper windings. For frequencies above 50MHz, verify the frequency-dependent inductance characteristics using an impedance analyzer and select lower inductance values to maintain consistent performance across your operating frequency range.
What is the maximum current rating for these inductors?
The saturation current varies by inductance value, ranging from approximately 2A for higher inductance values (68uH-100uH) to 8A for lower inductance values (1uH-10uH). The DC resistance also varies accordingly, from 0.05 ohms for low-inductance components to 0.8 ohms for high-inductance values. Always verify the specific saturation current for your selected inductance value and ensure your circuit design maintains current levels below saturation to prevent core saturation and efficiency loss.
Are these inductors suitable for automotive and industrial temperature ranges?
Yes, the CDRH CD104R inductors operate across the temperature range of -40 to +125 degrees Celsius, meeting automotive grade specifications for underhood applications and industrial control systems. The ferrite core material maintains stable inductance values across this temperature range with minimal temperature coefficient. However, verify the specific temperature coefficient for your selected inductance value, as some components may exhibit inductance variations of 10-15% across the full temperature range.
