70070K

Power Transformers Overview

The Talema Group LLC 70070K is a toroidal power transformer with a 35VA rating. It features dual 115V primaries for parallel or series connection at 115V or 230V respectively. The secondary offers dual 7V windings, providing 7V at 5A in parallel or 14V at 2.5A in series. Designed for through-hole PCB mounting, this low-profile component ensures compact integration.

Power Transformers Feature Summary

• Toroidal core construction for efficient magnetic coupling
• Dual primary windings supporting flexible voltage input configurations
• Low profile design minimizing vertical space requirements
• Through-hole termination for secure PCB attachment

Power Transformers Applications

• General purpose AC power supply units
• Audio equipment power stages
• Industrial control systems requiring isolated power
• Test and measurement instrumentation

Power Transformers Procurement Notes

Verify the specific ordering suffix to confirm exact lead times and packaging details. Ensure the procurement channel provides original manufacturer documentation. Confirm that the received unit matches the 70070K designation and physical dimensions. Check for any regional compliance certifications required for your target market before finalizing the order.

Power Transformers Selection Notes

Select this model when a 35VA capacity is required within a constrained vertical envelope. The dual secondary configuration allows flexibility between higher current/lower voltage or lower current/higher voltage outputs. Ensure the application supports through-hole mounting techniques and operates within standard frequency ranges compatible with toroidal designs.

Power Transformers Part Context

This component belongs to the 70000K series of low-profile PCB mounting toroidal transformers from Talema Group LLC. The series spans ratings from 1.6VA to 50VA, offering various voltage combinations. The 70070K specifically addresses mid-range power needs where space efficiency and robust isolation are prioritized over surface-mount convenience.

Power Transformers Replacement Considerations

Direct substitutes must match the 35VA rating, 115/230V primary options, and 7V/14V secondary outputs. Verify footprint compatibility for through-hole pins. Alternative models from the same series may offer different voltage taps but require verification of electrical equivalence.
