The P0502NL from Pulse Electronics, a YAGEO Group company, is an HCCI-80 surface-mount common mode choke designed for high-current power-line noise suppression. It uses a dual-winding 1:1 ±2% configuration for attenuating common-mode EMI while carrying substantial DC current, making it suitable for DC/DC converters and power-input filtering applications.
The device provides a nominal 470µH inductance with ±35% tolerance and is rated for 12Arms in Pulse’s current P688.U datasheet. The rated-current specification corresponds to a typical 50°C temperature rise under free-air cooling conditions.
Maximum DC resistance is only 8mΩ per winding, helping minimize conduction loss in high-current circuits. Typical electrical characteristics include 5.7µH leakage inductance, 10.1pF capacitance, 2.5MHz self-resonant frequency and approximately 3.60kΩ impedance at SRF.
The P0502NL carries a 600VDC voltage rating. Pulse specifies 1500Vrms dielectric strength and functional insulation for the SMT common-mode-choke family, supporting use in higher-voltage power-conversion and EMI-filtering circuits.
The HCCI-80 package measures up to 31.0 × 25.8 × 12.7mm and weighs up to approximately 17.8g. Operating temperature is -40°C to +125°C. Pulse specifies optional tape-and-reel packaging by adding a “T” suffix to the base part number.
