Description
12x12x7 mm CD127 Shielded SMD Power Inductor (CDRH127 Series)
The 12x12x7 mm CD127 Shielded SMD Power Inductor is a wire-wound, magnetically shielded surface mount power inductor built for DC-DC converters, buck/boost regulators and switch-mode power supplies (SMPS). Its ferrite drum core with a ferrite shield ring keeps magnetic flux contained, giving low EMI, low noise and stable inductance even on densely packed PCBs.
The 12 x 12 x 7 mm footprint (industry code 127 / CD127 / CDRH127 / SRR1207) offers high saturation current and low DC resistance (DCR) in a compact, low-profile SMD package that is compatible with reflow soldering and automated pick-and-place assembly.
Key Features
- Magnetically shielded construction for low EMI and minimal crosstalk
- High current handling with low DC resistance (DCR) for better efficiency
- Wire-wound ferrite core for stable inductance and low core loss
- Compact 12 x 12 x 7 mm low-profile SMD package
- Suitable for reflow soldering and automated SMT assembly
- RoHS compliant

How to Read the Marking Code
The printed 3-digit code shows inductance in microhenry (uH): the first two digits are the value and the third is the multiplier. Example: 100 = 10uH, 470 = 47uH, 101 = 100uH, 221 = 220uH. "R" marks a decimal point, e.g. 4R7 = 4.7uH.
