Import Encapsulated Pcb Power Transformer 0.35va - 20va — Buy in Bulk from Supplier in China

The Aiia Transformer encapsulated PCB power transformer operates at 50/60Hz with rated power ranging from 0.35VA to 20VA, designed for surface-mount or through-hole PCB integration. Core materials are cold-rolled silicon steel, with copper windings wound automatically to maintain consistent turns ratio and low leakage inductance. Output voltages are customisable within standard ranges such as 3.3V, 5V, 12V, or 24V AC secondary, with primary inputs matching common line voltages like 110V or 230V AC.

Each unit is encapsulated in UL-certified epoxy resin, providing moisture resistance, vibration damping, and electrical insulation without the need for external housing. The encapsulation process ensures compliance with IPC-A-610 Class 2 tolerances for solder joint integrity and component alignment. Typical no-load current is under 15mA at rated voltage, and temperature rise is limited to 55°C maximum under continuous full-load conditions, aligning with IEC 61558-2-1 standards for low-voltage transformers.

These transformers are commonly used in consumer electronics including smart home devices, medical monitors, security systems, and small appliance control boards. Buyers include OEM manufacturers sourcing for high-reliability, compact power solutions in mass-produced electronics. Trade terms are typically FOB Dezhou Port, with packaging in anti-static trays inside corrugated cartons. Minimum order quantity is not specified in the listing and should be confirmed directly with the supplier.

Aiia Transformer operates from Jintian Pioneering Park in Dezhou, Shandong Province, China, with manufacturing facilities focused on automated winding and resin encapsulation of low-power transformers. The company is verified as a harbor-tier supplier, indicating active trade history and documented export compliance, though no certifications such as ISO or CE are stated in the listing. Response metrics show no recorded communication activity, suggesting buyers should initiate direct inquiry for technical confirmation.

The supplier does not claim years in business, revenue figures, or client names. Its production process is described as fully automated with 100% testing prior to shipment, but no data on yield rates, testing equipment, or quality audits is provided. Buyers should request test reports for individual batches, particularly for parameters like insulation resistance and dielectric strength, which are not listed but critical for safety-critical applications.
