Key Features
- 530µH common mode inductance provides effective suppression of high-frequency EMI noise on balanced signal lines
- Ultra-low DCR of 0.015Ω minimizes insertion loss, preserving signal integrity in high-speed data interface applications
- SMD (surface mount) form factor enables automated pick-and-place assembly in compact, high-density PCB layouts
Applications
The P0527NL common mode choke is used to suppress electromagnetic interference (EMI) on differential signal pairs in Ethernet, DSL, and industrial communication interfaces. Its high 530µH inductance and low 0.015Ω resistance make it ideal for line filtering in power over Ethernet (PoE) ports, RS-485 bus interfaces, and VDSL modem front-end designs requiring compliance with FCC and CISPR 22 emission standards.

Frequently Asked Questions
What inductance and DCR specification does the P0527NL provide for EMI filtering?
The P0527NL common mode choke offers 530µH of common mode inductance with a DC resistance of only 0.015Ω per winding. This combination delivers strong attenuation of common mode noise from kilohertz through megahertz frequencies while keeping resistive signal loss to an absolute minimum.
For which communication interface standards is the P0527NL filter best suited?
The P0527NL is optimized for Ethernet, DSL (including ADSL and VDSL), and Power over Ethernet (PoE) line interfaces where common mode EMI suppression is required. Its 530µH inductance meets the filtering demands of IEEE 802.3 and ITU G.992 front-end filter designs operating in the 100kHz to 30MHz frequency range.
How does the SMD packaging of the P0527NL benefit high-volume PCB manufacturing?
The P0527NL surface mount package eliminates manual through-hole soldering, enabling automated pick-and-place and reflow soldering at standard 260°C peak temperatures. This reduces assembly cycle time and per-unit manufacturing cost while supporting high-density board layouts with smaller PCB footprints than equivalent through-hole chokes.
Can P0527NL replace similar common mode chokes from competing manufacturers in Ethernet port designs?
The P0527NL is directly interchangeable with common mode chokes sharing a 530µH inductance, 0.015Ω DCR, and equivalent SMD footprint from vendors such as Bourns and Murata, provided the current rating (typically 350mA to 500mA) and impedance profile match the target application's EMC filter specification.
