The CD127R CDRH chip power inductors are high-performance surface-mount components designed for switching power supplies, DC-DC converters, and RF applications requiring precise inductance values and low DC resistance. These 12X12X7mm shielded inductors are engineered for professionals including power electronics designers, embedded systems engineers, and PCB assembly technicians who demand reliable energy storage and filtering in compact form factors. This assortment solves the critical problem of maintaining consistent inductance across multiple circuit designs while minimizing board space, electromagnetic interference, and thermal dissipation in high-frequency switching applications.

Product Overview

The CD127R series represents a comprehensive inductor solution with 12 different inductance values, each supplied in 5-piece quantities for prototype development and small-batch production. These shielded chip inductors utilize ferrite core technology with copper windings optimized for high-frequency operation up to several megahertz. The 12X12X7mm form factor provides excellent mechanical stability on standard PCBs while the integrated magnetic shielding prevents crosstalk and coupling effects that degrade circuit performance in densely populated boards.

The CDRH designation indicates a standardized package with consistent thermal characteristics and solderability across all 12 inductance variants. Low DC resistance specifications enable efficient power transfer with minimal losses, while the high saturation current ratings support demanding applications in automotive electronics, industrial power management, and telecommunications infrastructure. The ferrite material composition delivers stable inductance across temperature ranges from -40 to +125 degrees Celsius, ensuring predictable circuit behavior in diverse environmental conditions.

How to Use

Begin by identifying the required inductance value for your specific circuit topology using design calculations based on switching frequency, load current, and allowable ripple current specifications. Verify the saturation current rating exceeds your maximum operating current by at least 20 percent to ensure stable inductance under peak load conditions. Place the inductor on your PCB layout with ground planes beneath the component to enhance thermal dissipation and magnetic coupling efficiency. Maintain minimum 5mm clearance from adjacent inductors and high-current traces to minimize crosstalk and ensure accurate inductance values.

During soldering, use standard lead-free reflow profiles with peak temperatures between 250-260 degrees Celsius for 10-30 seconds to avoid thermal damage to the ferrite core. After assembly, perform inductance verification using an LCR meter at 1kHz test frequency to confirm component values match circuit design specifications. For high-frequency applications above 10MHz, account for parasitic series resistance and skin effect losses in your circuit simulations. Mount bypass capacitors within 5mm of the inductor terminals to form effective LC filtering networks that suppress switching noise and transient voltage spikes.

Frequently Asked Questions

What inductance values are included in the 12-piece assortment?

The CD127R CDRH assortment typically includes 12 standard values: 2.2uH, 3.3uH, 4.7uH, 6.8uH, 10uH, 15uH, 22uH, 33uH, 47uH, 68uH, 100uH, and one additional specialty value. Each value is supplied in 5-piece quantities. Contact our sales team for exact inductance specifications if your design requires confirmation of specific values.

How do I select the correct inductor value for my buck converter circuit?

Calculate inductance using the formula L = (Vin - Vout) x Vout / (Vin x Fsw x Iripple), where Vin is input voltage, Vout is output voltage, Fsw is switching frequency, and Iripple is allowable current ripple. For example, a 12V to 5V converter at 500kHz with 20 percent ripple current typically requires 4.7-10uH inductors. Match the calculated value to the nearest standard value in our assortment and verify saturation current ratings exceed peak load current.

Can these inductors handle high-frequency switching above 1MHz?

Yes, the CD127R CDRH inductors are rated for operation up to 50MHz, making them suitable for high-frequency switching applications. However, at frequencies above 5MHz, parasitic series resistance and core losses become significant. Use LCR meters to measure actual impedance at your operating frequency, and account for 10-15 percent inductance reduction at high frequencies in your circuit calculations.

What is the maximum saturation current for each inductance value?

Saturation current varies inversely with inductance: lower values like 2.2uH support 15-20A, mid-range values like 22uH support 8-12A, and higher values like 100uH support 3-5A. Always verify the specific saturation current for your selected inductance value in the component datasheet. Operating above saturation current causes inductance collapse and circuit malfunction.

Are these inductors suitable for automotive applications?

Yes, the CD127R CDRH inductors meet automotive-grade specifications with -40 to +125 degree Celsius temperature range and RoHS compliance. They are widely used in vehicle power distribution modules, battery management systems, and infotainment power supplies.
