Applications
The Bourns SRF4532-110Y dual-function data line filter is designed for EMI suppression on USB 2.0, RS-232, RS-485, and Ethernet data lines in consumer electronics, industrial communication equipment, and embedded computing platforms. Its 11µH inductance and compact 4532 surface-mount form factor allow effective noise filtering without occupying significant PCB area in densely populated communication interface boards. The filter is also used in power line communication (PLC) systems and automotive infotainment data bus interfaces where reducing electromagnetic interference is critical for regulatory compliance with FCC and CE emission standards.

Frequently Asked Questions
What inductance value and DC resistance does the SRF4532-110Y provide for data line EMI filtering?
The SRF4532-110Y provides 11µH of inductance per function with a maximum DC resistance of 0.8Ω. The dual-function design filters both lines of a differential data pair simultaneously, while the low 0.8Ω resistance ensures minimal signal attenuation at DC and low frequencies in data bus lines carrying continuous 5V or 3.3V logic signals.
Which communication interfaces benefit most from the SRF4532-110Y data line filter in terms of EMI compliance?
The SRF4532-110Y is particularly effective on USB 2.0, RS-485, RS-232, and CAN bus data lines where common-mode noise generated by switching power supplies or adjacent digital circuits must be suppressed to meet FCC Part 15 Class B or CISPR 32 emission limits. Industrial equipment with serial communication ports and consumer electronics with USB interfaces commonly use this 11µH filter to pass radiated and conducted emission certification testing.
How does the 4532 package size and 2.8mm height of the SRF4532-110Y fit into compact PCB designs?
The 4532 surface-mount package measures 4.5mm in length by 3.2mm in width, with a 2.8mm maximum component height, making it a standard mid-size SMD inductor footprint widely supported by automated pick-and-place equipment. This compact form factor allows the dual-function filter to be placed directly adjacent to connector pins on densely populated I/O interface boards, minimizing the unfiltered trace length between the data connector and the filter for maximum EMI suppression effectiveness.
What is the minimum insulation resistance specification for the SRF4532-110Y, and why does it matter for safety-critical designs?
The SRF4532-110Y specifies a minimum insulation resistance of 10MΩ between its windings, which is critical for data line filters used in applications where the two filtered lines must maintain electrical isolation from each other or from ground. In medical devices, industrial instrumentation, and safety-rated communication interfaces requiring galvanic isolation characteristics, this 10MΩ minimum insulation ensures the filter does not create leakage paths that could compromise isolation barrier integrity or increase ground loop noise.
