Overview
The Würth Elektronik 744821201 is a 2-line common mode choke designed for effective EMI suppression in power delivery systems. Its primary function is to attenuate differential mode noise while allowing common mode currents to pass with minimal impedance. A critical design consideration for chokes of this inductance value (1 mH) is the trade-off between noise filtering effectiveness and potential saturation under high DC bias currents; engineers must carefully assess the expected operating current against the 2A rating to prevent performance degradation. This through-hole component offers robust filtering for demanding applications.
Key Features
- Inductance: 1 mH @ 10 kHz
- Current Rating: 2A maximum
- DC Resistance: 45 mOhm maximum
- Voltage Rating: 250V AC
- Operating Temperature: -40°C to 125°C
- Dimensions: 15.00mm (L) x 7.50mm (W) x 18.00mm (H)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Suppression of conducted EMI on AC power input lines
- Filtering for switching power supply output stages
- Noise reduction in motor drive control circuits
- Signal integrity enhancement in data acquisition systems
