Overview
The B82725S2253N40 is a current-compensated ring core double choke manufactured by EPCOS (TDK Electronics). It features a common mode inductance of 1 mH and supports a rated current of 25 A. The component operates at a rated voltage of 250 V AC (50/60 Hz) with a test voltage of 1500 V AC or 2100 V DC for two seconds. Designed for through-hole mounting, it utilizes a horizontal package configuration with four pins. The unit measures 44.00 mm in length, 42.40 mm in width, and has a maximum height of 25.00 mm.
Feature Summary
- Provides effective common mode noise suppression for power line applications
- Engineered for high current handling capabilities up to 25 A
- Constructed with a ring core design for stable electromagnetic performance
Applications
- Power supply input filtering
- Industrial equipment EMC protection
- Consumer electronics power lines
Procurement Notes
Verify the complete part number including the suffix N40 to ensure correct packaging specifications. Confirm that the required operating temperature range aligns with the component's rated thermal limits. Ensure the mounting hole pattern matches the horizontal four-pin layout dimensions provided in the official datasheet before finalizing procurement orders.
Selection Notes
Select this component when a 1 mH inductance value is required for common mode interference reduction in circuits carrying up to 25 A. The 250 V AC rating suits standard mains frequency applications. Consider the physical dimensions of 44.00 mm x 42.40 mm x 25.00 mm for adequate PCB space allocation and mechanical clearance during installation.
Part Context
This component belongs to the B82725 series of current-compensated ring core double chokes from EPCOS (TDK Electronics). These chokes are designed for robust performance in filtering applications where high current capacity and reliable noise suppression are critical requirements for maintaining signal integrity in power systems.
Replacement Considerations
Cross-reference with other B82725 series variants such as B82725S2123N40 for different inductance values. Verify pin compatibility and physical footprint alignment before substituting any alternative components to ensure proper integration into existing circuit designs.
