Overview
The BV020-5427.0 is a laminated core power transformer manufactured by Pulse Electronics. It features a primary voltage rating of 230V and a secondary voltage output of 18V. The unit provides an apparent power capacity of 0.35VA, supporting a maximum secondary current of 19mA. Designed for through-hole mounting, this component utilizes a laminated core construction to facilitate efficient energy transfer in standard AC power applications.
Feature Summary
- Laminated core construction for stable magnetic flux
- Through-hole termination style for board integration
- Step-down voltage conversion from 230V primary to 18V secondary
Applications
- Low-power AC signal conditioning circuits
- Isolation stages in consumer electronic devices
- Power supply input stages requiring 18V output
Procurement Notes
Verify the specific datasheet version for insulation class and safety certifications prior to integration. Confirm that the 0.35VA rating meets the load requirements of the target circuit. Ensure through-hole footprint compatibility with the printed circuit board design. Check for any RoHS compliance status updates if environmental regulations apply to the final assembly.
Selection Notes
Select this component when a fixed step-down ratio from 230V to 18V is required at low power levels. The 0.35VA rating limits suitability to small loads; higher power needs require larger transformers. Through-hole mounting dictates PCB layout constraints compared to surface-mount alternatives. Verify frequency compatibility with the source AC line.
Part Context
This part belongs to the Power Transformers category within Pulse Electronics' portfolio. It serves as a specialized component for low-voltage isolation and conversion tasks. The laminated core design distinguishes it from toroidal or planar variants, offering a cost-effective solution for standard industrial and consumer power applications where space is not severely constrained.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. When replacing this obsolete item, engineers must match the 230V primary, 18V secondary, and 0.35VA power ratings. Through-hole pin spacing and physical dimensions should be verified against potential alternative manufacturers' offerings.
