High Frequency Transformers

📊 KATOY High-Frequency Transformers

A high-frequency transformer is a type of transformer designed to operate at frequencies higher than the standard 50/60 Hz, typically in the kHz to MHz range. These transformers are key components in switch-mode power supplies (SMPS), inverters, and various modern electronic circuits.

Katoy can manufacturer high-frequency transformerss to any specification required for your application.

⚙️ Key Features of High-Frequency Transformers

Core Material: Usually made from ferrite to reduce eddy current losses at high frequencies.
Compact Size: Much smaller than low-frequency transformers of the same power rating.
Lightweight: Less core material is needed because of higher frequency operation.
Efficient: Better power transfer with reduced size and losses.
Fast Response: Suitable for high-speed switching and regulation.

🔩 Physical Characteristics

Encapsulation: Most are enclosed in rectangular plastic casings.
Windings: Visible yellow insulation tape wrapping around the coil areas.
Terminals: Multiple pin terminals on the bottom, designed for PCB mounting.
Lead Types:
- Some have through-hole pins.
- A few have wire leads (suggesting higher current applications or off-board mounting).
Core Types:
- Likely EE, EI, or EC ferrite core shapes inside (common in SMPS designs).
- A few might be EFD or PQ cores which are optimized for flat profiles.

📏 Variety

We manufacture a range of sizes, including different voltage and power ratings.
Larger units with more winding separation may handle higher power or multi-output configurations.
Smaller units are likely used for signal isolation or low-power supplies.
