Overview
The C201388A-102 is a two-line common mode choke manufactured by ITG Electronics, Inc. It features an inductance of 1 mH measured at 10 kHz and supports a maximum current rating of 4.4 A. The component exhibits a direct current resistance (DCR) of 19.5 mOhm. Designed for through-hole mounting, it operates within a temperature range of -40°C to 125°C and carries an AC voltage rating of 250 V. Its physical dimensions are 0.650 inches in length by 0.394 inches in width.
Feature Summary
- Provides common mode noise suppression for two-line circuits
- Supports high current operation up to 4.4 A
- Designed for reliable performance across extended temperature ranges
Applications
- EMI filtering in power supply inputs
- Noise suppression in data communication lines
- Common mode interference reduction in industrial equipment
Procurement Notes
Verify the specific part number suffix against official ITG Electronics documentation to ensure correct inductance and current ratings. Confirm that the through-hole package dimensions match the target PCB layout requirements. Check for RoHS compliance status if required by assembly specifications. Ensure the operating temperature range meets the environmental conditions of the final application.
Selection Notes
Select this component when a 1 mH inductance at 10 kHz is required for common mode noise attenuation. Ensure the circuit current does not exceed the 4.4 A rated limit to prevent saturation or overheating. Verify that the 19.5 mOhm DCR aligns with efficiency constraints. Confirm that the through-hole mounting style is compatible with the manufacturing process.
Part Context
This component belongs to the C201388A series of common mode chokes from ITG Electronics, Inc. The series includes variants with different inductance values and current ratings, such as the C201388A-802 and C201388A-351. These components are designed for EMI filtering applications requiring robust magnetic performance in a standard DIP package format.
Replacement Considerations
The C201388A-802 offers 8 mH inductance with a 1.8 A rating. The C201388A-351 provides 0.35 mH inductance with a 6.5 A rating. Substitution requires verification of inductance, current capacity, and physical footprint compatibility.
