Overview
The BWCU00231512261M02 is a surface-mount common mode choke manufactured by Pulse Electronics. It features an unshielded design with SMD/SMT termination for PCB mounting. The component operates within a temperature range of -40°C to +105°C and has physical dimensions of 2.3 mm length, 1.5 mm width, and 1.2 mm height. Key electrical specifications include an impedance of 260 Ohms at a test frequency of 100 MHz, a maximum DC current rating of 700 mA, and a maximum DC resistance of 600 mOhms.
Feature Summary
- Provides common mode noise filtering for high-speed data lines
- Designed specifically for USB 2.0, IEEE1394b, and LVDS applications
- Utilizes an unshielded construction suitable for standard PCB layouts
Applications
- USB 2.0 interface protection
- IEEE1394b (FireWire) signal integrity enhancement
- LVDS (Low-Voltage Differential Signaling) circuit filtering
Procurement Notes
Verify the specific impedance tolerance and DC current ratings against the official datasheet before integration. Confirm that the unshielded package style meets the electromagnetic interference requirements of the target application. Ensure the operating temperature range aligns with the environmental conditions of the final device assembly.
Selection Notes
Select this component when designing circuits requiring common mode rejection for differential signaling standards such as USB 2.0 or FireWire. Consider the 260 Ohm impedance value at 100 MHz for effective noise suppression without significant signal attenuation. Evaluate the 700 mA current capacity to ensure it exceeds the operational current demands of the protected lines.
Part Context
This part belongs to the BWCU series of common mode chokes from Pulse Electronics. It is functionally similar to other models in the series, such as BWCU00231512121M02, which offers different impedance characteristics. The series is designed for compact electronic devices requiring reliable EMI suppression in space-constrained environments.
Replacement Considerations
Direct substitutes may include other BWCU series parts with compatible impedance and current ratings. Verify pin compatibility and mechanical footprint equivalence before substitution.
