Overview
The B82746S6702A040 is a three-line common-mode choke from the EPCOS B82746 series, designed for power line filtering. It features an inductance of 6.2 mH at 10 kHz and supports a maximum current rating of 8 A. The component has a typical DC resistance of 18 mOhm and is rated for AC voltages of 440 V and 250 V. Constructed for through-hole mounting, it operates within a standard temperature range to ensure reliable noise suppression in industrial and automotive applications.
Feature Summary
- Provides effective common-mode noise attenuation for three-phase power lines
- Supports high current loads up to 8 amperes with low impedance loss
- Engineered for robust performance in demanding industrial and automotive environments
Applications
- Three-phase motor drive systems
- Industrial power supply units
- Automotive electronic control modules
Procurement Notes
Verify the specific ordering suffix against official TDK documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with existing board layouts and thermal management requirements before finalizing procurement decisions.
Selection Notes
Select this component when three-phase noise suppression is required alongside high current handling capabilities. Evaluate the 6.2 mH inductance value against system frequency requirements and confirm that the 8 A current rating exceeds peak operational loads to prevent saturation.
Part Context
This component belongs to the B82746 series of common-mode chokes manufactured by EPCOS, now part of TDK Electronics. The series is widely recognized for providing reliable electromagnetic interference filtering in power electronics, serving both industrial machinery and automotive sectors with standardized through-hole solutions.
Replacement Considerations
Consult official TDK cross-reference lists for verified substitutes. Ensure any replacement maintains identical three-line configuration, 6.2 mH inductance, and 8 A current rating to preserve circuit integrity.
