Frequently Asked Questions

Q: What is an EI14 audio isolation transformer used for?

A: An EI14 audio isolation transformer is a passive electronic component used to electrically isolate two audio circuits while allowing the audio signal to pass through. It is commonly used in radio communication systems, broadcast equipment, amplifier circuits, and automatic control systems to prevent ground loops and reduce electromagnetic interference (EMI).

Q: What does 600:600 ohm 1:1 mean for this transformer?

A: A 600:600 ohm impedance ratio means the primary (input) and secondary (output) windings have equal impedance — 600 ohms each — making this a 1:1 transformer. This is a standard balanced audio line impedance, ideal for connecting two audio stages without signal loss or impedance mismatch. The 1:1 voltage ratio means the output voltage mirrors the input voltage.

Q: Are these transformers lead-free and RoHS compliant?

A: Yes. These EI14 audio isolation transformers are manufactured with lead-free compliant electronic components, making them suitable for use in products that must meet RoHS (Restriction of Hazardous Substances) standards.

Q: How many transformers come in one order?

A: Each order includes a pack of 50 EI14 audio isolation transformers. This bulk quantity is perfect for electronics engineers, hobbyists, and prototypers who need a reliable supply of consistent components.

Q: What voltage range is this transformer rated for?

A: These transformers are rated for low-voltage applications: below 50V AC or 75V DC. They are not intended for use in high-voltage circuits.
