Overview
The Bourns Inc. 7406-RC is a through-hole common mode choke designed for power line filtering applications. It features two lines with an inductance of 2 mH measured at 1 kHz. The component supports a maximum current rating of 1.8A and has a maximum DC resistance (DCR) of 110mOhm. It operates within a temperature range of -55°C to 105°C and is rated for an AC voltage of 250V.
Feature Summary
- Provides common mode noise suppression for dual-line power circuits
- Constructed for reliable through-hole mounting on printed circuit boards
- Engineered to handle high current loads with low DC resistance
Applications
- Power supply input filtering
- Industrial control equipment EMI suppression
- Medical electronic device noise reduction
Procurement Notes
Verify the exact part number 7406-RC against official Bourns documentation to confirm specifications such as inductance, current rating, and package type. Ensure compliance with RoHS3 standards if required by your design. Cross-reference datasheets from authorized distributors to validate technical parameters before procurement.
Selection Notes
Select this component when designing circuits requiring common mode chokes for power lines with currents up to 1.8A. Consider the 2 mH inductance value for effective noise attenuation at 1 kHz. Ensure the PCB layout accommodates through-hole mounting and that the operating environment stays within the specified -55°C to 105°C temperature range.
Part Context
This component belongs to Bourns' series of common mode chokes, which are passive electronic components used to suppress electromagnetic interference. These devices typically consist of windings on a magnetic core, designed to block high-frequency noise while allowing differential signals or power to pass unaffected.
Replacement Considerations
Consult official Bourns substitution guides or distributor cross-reference tools for verified equivalent parts. Ensure any substitute matches the 2 mH inductance, 1.8A current rating, and through-hole package dimensions.
