Overview
The BWCC00201208181M02 is a two-line common mode choke manufactured by Pulse Electronics. It features an impedance of 180 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 700 mA. The component has a maximum DC resistance of 400 mOhms and operates within a temperature range of -55°C to +125°C. Its physical dimensions are 2 mm in length, 1.25 mm in width, and 0.9 mm in height, housed in an 0805 surface mount package.
Feature Summary
- Designed for high-frequency noise suppression in differential data lines
- Utilizes Chilisin RF inductor technology for signal integrity
- Provides shielding to minimize electromagnetic interference
Applications
- USB 2.0 interface protection
- IEEE 1394 (FireWire) bus filtering
- LVDS signal line conditioning
- HDMI 1.4 port noise reduction
Procurement Notes
Verify the specific manufacturer designation on the datasheet, as some sources associate this part number with Chilisin RF inductors rather than Pulse Electronics directly. Confirm RoHS compliance status and exact packaging quantities before ordering. Ensure the supplier provides official documentation to validate the component's origin and specifications.
Selection Notes
Select this component for applications requiring compact EMI filtering on high-speed digital interfaces. The 0805 footprint suits space-constrained designs. Evaluate the 700 mA current rating against the system's operational requirements to ensure adequate headroom. Consider the 180 Ohm impedance profile for effective attenuation at target frequencies.
Part Context
This component belongs to the category of surface mount common mode chokes used in consumer electronics and computing peripherals. It addresses electromagnetic compatibility challenges in portable devices and energy-efficient systems where signal integrity is critical for reliable data transmission across standard communication buses.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material.
