Overview
The 14A-30-28B35 is a split bobbin power transformer manufactured by Pulse Electronics, designed for through-hole mounting on printed circuit boards. It features a laminated core construction and delivers a total power rating of 30 VA. The unit provides an output voltage range of 14 to 28 volts with a secondary current rating of 1.06 amps. This component is RoHS compliant and lead-free, suitable for applications requiring reliable low-frequency power transformation in industrial or commercial electronic systems.
Feature Summary
- Split bobbin design for enhanced isolation and reduced electromagnetic interference
- Laminated core construction optimized for low-frequency power efficiency
- Through-hole mounting configuration for secure PCB integration
Applications
- Industrial control systems requiring isolated power supplies
- Commercial equipment needing stable low-voltage AC outputs
- General-purpose power conversion in electronic assemblies
Procurement Notes
Verify the specific datasheet version for the 14A-30-28B35 to confirm exact electrical tolerances and thermal characteristics before integration. Ensure that the procurement channel provides official documentation from Pulse Electronics to guarantee authenticity. Cross-reference the pinout and physical dimensions against your PCB layout requirements to avoid mechanical mismatches during assembly.
Selection Notes
Select this transformer when a 30 VA capacity with a 14-28V output range is required for through-hole implementations. Consider the split bobbin architecture if improved isolation between primary and secondary windings is necessary for safety compliance. Evaluate the laminated core performance against your specific frequency and efficiency needs compared to alternative toroidal or E-core options.
Part Context
This component belongs to Pulse Electronics' line of split bobbin power transformers, which are engineered for robust performance in demanding environments. The series typically offers various voltage and wattage configurations to suit diverse power supply designs. These transformers are widely used in sectors where reliability and regulatory compliance, such as RoHS standards, are critical for product certification.
Replacement Considerations
Consult official Pulse Electronics substitution guides for direct equivalents. Verify that any alternative part matches the 30 VA rating, 14-28V output, and through-hole footprint to ensure functional compatibility without redesigning the host circuit board.
