Overview
The PMCU-4100 is a common mode choke from Premier Magnetics designed for EMI/RFI suppression in data line applications. It features a low-profile horizontal construction suitable for through-hole mounting. The component provides an inductance of 10 mH at 1 kHz with a DC resistance (DCR) of 1.4 Ohms. It supports a rated RMS current of 450 mA and operates within a temperature range of -40°C to +80°C. The device handles a rated voltage of 250Vac at 45/400Hz and offers 3750Vrms isolation.
Feature Summary
- Low-profile horizontal construction for compact board integration
- High isolation rating of 3750Vrms for safety compliance
- Designed for effective EMI/RFI noise suppression in data lines
Applications
- Data line filtering
- EMI/RFI common mode line filters
- Power line signal conditioning
Procurement Notes
Verify the specific package type and pin configuration against the official datasheet before integration. Confirm that the 450mA current rating meets the operational requirements of the target circuit. Ensure compatibility with the 250Vac voltage specification. Check for RoHS compliance status if required by project standards. Validate supplier authenticity to guarantee component integrity.
Selection Notes
Select this component when high inductance is required for low-frequency noise attenuation in data lines. The 1.4 Ohm DCR should be evaluated against power loss constraints. Consider the 450mA current limit for load capacity. The low-profile design is advantageous for space-constrained enclosures. Verify thermal performance under continuous operation within the specified temperature range.
Part Context
This part belongs to the PMCU-XXXX series of EMI/RFI common mode line filters manufactured by Premier Magnetics, Inc. The series includes various models with different inductance and current ratings, such as PMCU-4015 and PMCU-4470. These components are generally used for signal conditioning and power conversion applications requiring robust noise suppression.
Replacement Considerations
Cross-reference with other PMCU series models like PMCU-4015 or PMCU-4220 if different inductance values are needed. Ensure any substitute maintains the 3750Vrms isolation and similar physical dimensions for mechanical compatibility.
