Common Mode Chokes datasheet and documents for PA2742NL

PA2742NL

Common Mode Chokes Overview

The PA2742NL is a surface-mount common mode choke manufactured by Pulse Electronics. It features an inductance of 397 µH and supports a maximum DC current of 1 A. The component has a maximum DC resistance of 92 mΩ and an impedance of 1.4 kΩ at 100 MHz. Its self-resonant frequency is 2.5 MHz. The device operates within a temperature range of -40°C to +125°C. Physical dimensions are 9.1 mm x 8.9 mm x 7.9 mm.

Common Mode Chokes Feature Summary

Provides common mode noise suppression for two-line circuits via surface mount technology.
Utilizes a toroidal core design for efficient magnetic field containment.
Engineered for high reliability with RoHS compliance.

Common Mode Chokes Applications

Signal line filtering in electronic equipment
Noise suppression in data transmission interfaces
EMI reduction in power supply input stages

Common Mode Chokes Procurement Notes

Verify the specific datasheet revision, as Pulse Electronics issues Product Change Notifications (PCNs) that may alter physical or electrical characteristics. Confirm package orientation and pinout compatibility during integration. Ensure storage conditions adhere to moisture sensitivity level requirements before reflow soldering. Cross-reference manufacturer part numbers with distributor codes to avoid sourcing errors.

Common Mode Chokes Selection Notes

Select this component when a 397 µH inductance and 1 A current rating are required for common mode noise attenuation. Compare the 92 mΩ DCR against system loss budgets. Evaluate the 9.1 mm x 8.9 mm footprint against PCB space constraints. Consider the 125°C operating limit for thermal management in enclosed environments.

Common Mode Chokes Part Context

The PA2742NL belongs to the Pulse Electronics SMT Common Mode Chokes series, which offers various package sizes and current ratings from 1 A to 20 A. This specific model is categorized under High Shasta packages, distinguishing it from Low Shasta variants like the PA2741NL. The series targets applications requiring robust EMI filtering in compact surface-mount designs.

Common Mode Chokes Replacement Considerations

Direct substitutes include other 397 µH, 1 A common mode chokes with compatible footprints. Verify inductance tolerance, current saturation levels, and impedance curves match original specifications. Check for equivalent RoHS compliance and operating temperature ranges before substitution.
