Overview
The C201021A-103NHF is a two-line common mode choke manufactured by ITG Electronics, Inc. It features a through-hole mounting style and operates within an ambient temperature range of -40°C to +125°C. The component provides an inductance of 10 mH at a test frequency of 10 kHz with a tolerance of ±30%. It supports a maximum current rating of 1 A and exhibits a DC resistance (DCR) of 345 mOhm. The device is rated for an AC voltage of 250 V and complies with RoHS and HF standards.
Feature Summary
- Provides common mode noise suppression for two-line circuits
- Utilizes a through-hole package design for PCB insertion
- Operates reliably across a wide industrial temperature range
Applications
- LED lighting applications
- Switch mode power supply input filtering
- General EMI suppression in electronic equipment
Procurement Notes
Verify the specific part number suffix against official manufacturer documentation to ensure correct inductance and tolerance specifications. Confirm that the through-hole footprint matches the target PCB layout. Check for RoHS compliance requirements if operating in regulated environments. Ensure the current rating meets the circuit's peak load demands without saturation.
Selection Notes
Select this component when designing circuits requiring common mode noise attenuation for low-current applications. The 1 A rating suits LED drivers and small power supplies. Consider the 345 mOhm DCR impact on efficiency. The wide temperature range allows use in harsh environments. Verify pin spacing compatibility with assembly processes.
