Overview
The SPT-204 is an audio transformer manufactured by Prem Magnetics, Inc., designed for driver applications. It features a primary impedance of 10KCT and a secondary impedance of 2KCT. The component utilizes a through-hole mounting type with PC pin termination style. Its physical dimensions are specified as 0.598 inches in length by 0.472 inches in width (15.20mm x 12.00mm). The device is classified as an economical open-type transformer.
Feature Summary
- Provides specific impedance transformation between primary and secondary windings for audio driver circuits
- Utilizes through-hole mounting technology with PC pin terminations for board integration
- Constructed as an economical open-type design suitable for standard audio applications
Applications
- Audio driver transformer circuits
- Impedance matching in audio signal paths
- Through-hole PCB assembly for audio equipment
Procurement Notes
Verify the specific impedance ratio configuration matches the target circuit requirements before procurement. Confirm that the through-hole package dimensions align with the printed circuit board layout constraints. Ensure the supplier provides documentation confirming RoHS compliance status if required by the manufacturing process specifications.
Selection Notes
Select this component when a dedicated audio driver transformer with a 10KCT to 2KCT impedance ratio is required. Consider the through-hole form factor and open construction type against available surface-mount alternatives. Evaluate the physical size constraints of the enclosure to ensure the 15.20mm x 12.00mm footprint fits within the designated area without interference.
Part Context
The SPT-204 belongs to the audio transformer product line from Prem Magnetics, Inc. This series includes various transformers such as the SPT-304 and SPT-403, catering to different audio impedance needs. The SPT-204 specifically addresses driver stage requirements, distinguishing it from general-purpose power or signal transformers offered by the manufacturer.
Replacement Considerations
Cross-reference with other Prem Magnetics audio transformers like the SPT-304 for alternative impedance ratios. Verify compatibility with equivalent components from other manufacturers offering similar 10KCT:2KCT audio driver transformers.
