Overview
The EH20-0.3-02-33M is a current compensated common mode choke manufactured by TE Connectivity / Schaffner. It features a ferrite core and is designed for PCB mounting via through-hole termination. The component provides an inductance of 33 mH with a tolerance of 15%. It supports a maximum DC current of 300 mA and has a maximum DC resistance of 1.25 Ohms. The device operates within a temperature range of -25°C to +100°C. Its physical dimensions are 21 mm x 21 mm x 17.8 mm, and it is unshielded.
Feature Summary
- Provides common mode noise suppression for power lines
- Utilizes a ferrite core for magnetic performance
- Designed for through-hole printed circuit board installation
Applications
- Power supply input filtering
- Electromagnetic interference suppression in electronic equipment
- Common mode choke applications in low current circuits
Procurement Notes
Verify the manufacturer part number EH20-0.3-02-33M against official TE Connectivity or Schaffner documentation to ensure authenticity. Confirm that the specific order matches the required electrical parameters, including the 33 mH inductance and 300 mA current rating. Check for any specific RoHS compliance details provided in the latest datasheet before finalizing procurement.
Selection Notes
Select this component when a through-hole common mode choke with 33 mH inductance is required for low current applications up to 300 mA. Ensure the PCB layout accommodates the 21 mm x 21 mm footprint and 17.8 mm height. Verify that the operating environment stays within the specified -25°C to +100°C temperature range and that the unshielded design does not interfere with nearby sensitive components.
Part Context
This component belongs to the EH series of common mode chokes from Schaffner, now part of TE Connectivity. The EH series is characterized by its use in RFI suppression and EMC filtering for power lines. These chokes are typically used in conjunction with other filter components to meet electromagnetic compatibility standards in various electronic devices.
Replacement Considerations
Cross-reference with similar Schaffner EH series parts such as EH20-0.5-02-18M for different current or inductance requirements. Ensure any substitute maintains the same through-hole package dimensions and voltage ratings.
