DFC7045 Series

Common Mode Chokes

The DFC7045 Series automotive-grade common mode chokes feature a compact chip-style construction, manufactured with a highly automated process to ensure exceptional quality, reliability, and cost-effectiveness.
Optimized for high frequency common mode noise suppression, the DFC7045 offers a small footprint with high current capability, making it an excellent choice for EMI filtering in power lines.

Automotive-qualified, this series is ideal for automotive DC/DC converters and power supplies that require compact, high-performance EMI suppression in space-constrained designs.

Miniature, low-profile common mode choke; only 3.3 mm tall
Smaller footprint and higher current capability than typical parts on the market
Provides exceptional high-frequency common mode noise attenuation
Designed and fabricated for systems mounted in harsh automotive conditions
AEC-Q200 qualified

메모

When ordering, please specify termination and packaging codes: e.g. DFC7045-502RC
Inductance is measured at 100 kHz, 0.1 Vrms, 0 ADC on an Agilent 4263B (or equivalent).
Leakage Inductance LL is measured at 100 kHz, 0.1 Vrms on an Agilent 4263B (or equivalent) with pins 3,4 shorted.
Irms: Current that causes a 40°C temperature rise from 25°C.
DCR is measured on a Keithley 580 Micro-ohmmeter (or equivalent). For other operating temperatures, use this DCR at Temperature calculator.
1500 VDC / 1060 Vrms, one minute isolation (hipot) measured between primary and secondary.
