LPTC-V-42.5-2-200

Common Mode Chokes Overview

The LPTC-V-42.5-2-200 is a two-line common mode choke manufactured by Signal Transformer, designed for through-hole mounting. It features an inductance of 42.5 mH measured at 1 kHz and supports a maximum DC current of 2 A. The component has a maximum DC resistance (DCR) of 200 mOhms. It operates within a temperature range of -55°C to a specified upper limit, utilizing a toroidal core structure.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression for dual-line circuits
• Utilizes a toroidal core design for efficient magnetic coupling
• Supports high current handling up to 2 A with low DC resistance

Common Mode Chokes Applications

• Power line filtering in electronic equipment
• EMI suppression in AC/DC power supplies
• Signal integrity protection in data transmission lines

Common Mode Chokes Procurement Notes

Verify the specific datasheet version for precise thermal ratings and insulation specifications. Confirm that the through-hole footprint matches the target PCB layout dimensions. Ensure the 2 A current rating aligns with the operational requirements of the circuit to prevent saturation or excessive heating during continuous use.

Common Mode Chokes Selection Notes

Select this component when high inductance values are required for effective low-frequency noise attenuation. The 200 mOhm DCR minimizes voltage drop across the choke. Consider the physical size constraints as the toroidal package requires adequate clearance on the printed circuit board for proper installation and heat dissipation.

Common Mode Chokes Part Context

This part belongs to the LPTC-V series of common mode chokes from Signal Transformer. The series offers various inductance options tailored for different filtering needs. The LPTC-V-42.5-2-200 specifically addresses applications requiring robust noise rejection with moderate current capacity in a standard through-hole configuration.

Common Mode Chokes Replacement Considerations

Direct substitutes include other 42.5 mH common mode chokes with similar current ratings. Verify pin compatibility and mechanical dimensions before substitution. Alternative models from the same manufacturer may offer adjusted inductance or current capabilities.
