In high-noise environments like industrial automation and telecom infrastructure, unstable Power Inductor performance can lead to system failures and costly downtime. Our LOH-S series solves this with ferrite-shielded construction—delivering up to 6A current rating (LOH2220S-R27M) and 0.007Ω ultra-low DCR while suppressing EMI by 20dB. Unlike conventional unshielded inductors, we integrate magnetic shielding directly into the SMD Inductor structure, eliminating the need for external EMI Filter components and reducing total BOM cost by 30%.
| Parameter | LOH1210S-1R0M | LOH2220S-R27M | Industry Average (Unshielded) |
|---|---|---|---|
| Inductance | 1.0µH ±20% | 0.27µH ±20% | ±30% tolerance |
| Max DCR | 0.02Ω | 0.007Ω | 0.05Ω+ |
| Rated Current (IDC) | 1000mA | 6000mA | 3000mA |
| SRF | 120MHz | 300MHz | Unspecified |
| Operating Temp | -25°C to +85°C | -25°C to +85°C | -40°C to +105°C |
| Shielding | Ferrite Shielded | Ferrite Shielded | Non-Shielded |
Testing Standards:
The ferrite shield reduces radiative noise by 20dB at 100MHz—critical for PLC control systems and automotive radar modules where external EMI Filter add-ons consume 15% more PCB space. This exceeds the performance of unshielded rivals like Sumida’s CDMC series.
Despite a miniature 1210 package (3.5×2.8mm), the LOH1210S handles 1A continuous current with ≤40°C temperature rise. Ideal for space-constrained designs like drone motor controllers and IoT gateways where cooling is limited.
Operates flawlessly from -25°C to +85°C with ≤10% inductance drop at rated current. The molded construction resists vibration-induced cracking—validated in 500-hour stress tests for automotive applications (exceeding AEC-Q200 benchmarks).
| | Recommended Model | Performance Result | Cost Savings vs. Alternatives |
|---|---|---|---|
| PLC I/O Modules | LOH2220S-1R0M | 40% lower noise vs. open-core inductors | $0.22 saved on EMI filters |
| xDSL Line Filters | LOH1210S-470K | Passed GR-1089 surge tests | 15% smaller than TDK SLF12565T |
| LED Drivers | LOH1210S-2R2M | 94% efficiency @ 2A load | 20% lower DCR vs. MOX-DAI-1310 |
Place inductor ≥3mm from Sensor or ADC traces to reduce coupling noise
Use guard rings around inductor pads if unshielded RF Inductor must be nearby
Thermal vias under thermal pads recommended for currents >3A
RoHS 3.0 / REACH SVHC
ISO 9001:2015 certified manufacturing
100% automated final test (Hi-POT, IR, LCR)
"The 0.007Ω DCR on LOH2220S-R27M cut our motor driver losses by 22% while the built-in shielding helped pass CISPR 32 Class B without extra filters."
