Overview
The UU9LFHNP-HB102 is a two-line common mode choke manufactured by Sumida America Components Inc. It features an inductance of 1 mH measured at 1 kHz and supports a maximum DC current of 700 mA. The component has a maximum DC resistance (DCR) of 350 mOhms. Designed for through-hole PCB mounting, it operates within a temperature range of -40°C to +85°C. The physical dimensions are 16.5 mm in length, 11 mm in width, and 16.5 mm in height.
Feature Summary
- Provides common mode noise suppression for two-line circuits
- Utilizes through-hole termination for printed circuit board integration
- Constructed with ferrite core technology for magnetic shielding
Applications
- AC line filtering in power supply inputs
- Noise suppression in data communication interfaces
- EMI reduction in consumer electronic devices
Procurement Notes
Verify the specific suffix HB against the manufacturer's official datasheet to confirm pinout and mechanical tolerances. Ensure the selected variant matches the required 700 mA saturation current and 350 mOhm DCR specifications for the target application. Cross-reference the RoHS compliance status with the latest regulatory documentation provided by Sumida before finalizing procurement orders.
Selection Notes
Select this component when a through-hole solution is required for low-frequency common mode noise attenuation. The 1 mH inductance value is suitable for standard AC line frequencies. Compare the 700 mA current rating against the peak load requirements of the circuit to ensure adequate headroom. Consider the 16.5 mm height constraint during PCB layout planning to avoid mechanical interference with adjacent components or enclosures.
Part Context
This part belongs to Sumida's UU9LF series of common mode chokes, designed for general-purpose EMI filtering. The series offers various inductance values and current ratings tailored for different power and signal integrity needs. The UU9LFHNP-HB102 specifically targets applications requiring robust through-hole mounting and moderate current handling capabilities for two-line configurations.
Replacement Considerations
Direct substitutes include the UU9LFNP-B102 from Sumida, which shares identical electrical parameters including 1 mH inductance, 700 mA current rating, and 350 mOhm DCR. Verify mechanical footprint compatibility before substitution.
