Pin count
Sets the number of winding taps and the board footprint. Parts with different pin counts are not drop-in replacements for each other.

6 PIN Audio Transformers
Six pins expose taps on both windings, so a balanced input and a balanced output can share one part. That flexibility costs board area and makes the layout more sensitive, so confirm the pinout and keep the balanced pairs symmetric before you commit.

By pin count
Choose an audio transformer by pin count
Pin count sets the winding taps and the board footprint, so start from the circuit you have.
選定方法
Selecting an audio transformer in four steps
Work from the source and load impedance outward to the mechanical constraints.
- 01
Fix the impedance on both sides
State the source impedance, load impedance, signal level and frequency range, and whether the stage has to convert balanced to unbalanced.
- 02
Derive the turns ratio
The impedance ratio is the square of the turns ratio. A 600:600 part is 1:1; stepping 600 down to 150 ohm needs a 2:1 turns ratio.
- 03
Check level and isolation
Confirm the maximum signal level the core can carry without saturating, then confirm the dielectric strength the safety case demands.
- 04
Confirm the footprint
Match pin count, pin pitch and height against the board, then verify insertion loss and frequency response on your own hardware.
Parameters
What the audio transformer datasheet values mean
Each figure is measured under stated conditions; read the conditions with the number.
AC impedance
Quoted for a stated frequency, commonly 1 kHz. Read the test frequency with the value; the same part reads differently elsewhere in the band.
Turns ratio
Fixes the impedance transformation and the voltage relationship between windings. Impedance ratio equals turns ratio squared.
DC resistance
Winding copper loss. It adds to insertion loss and matters most when the winding also carries a bias current.
Dielectric strength
The isolation the barrier withstands under the stated test. Choose against the safety requirement, not against the working voltage alone.
Insertion loss
Signal lost through the transformer at the stated frequency. Compare candidates at the same frequency or the numbers do not mean the same thing.
比較
Audio transformer families side by side
Pin count and impedance separate the families more than package size does.

用途別確認
Where audio transformers are used
Confirm line level, balanced wiring and the impedance ratio the circuit expects.
Professional audio and broadcast
- Confirm line level, balanced wiring and the impedance ratio, then check insertion loss and frequency response across the audio band.
Intercom and paging systems
- Long runs pick up ground noise. Verify the isolation rating and that the core handles the maximum drive level without saturating.
Industrial and instrumentation audio
- Check the dielectric strength against the safety case, and confirm the operating temperature range covers the enclosure.
Consumer audio interfaces
- Height and footprint usually decide. Confirm the pin pitch and that frequency response holds at the levels the interface actually uses.

カテゴリー概要
What an audio transformer does, and why 600 ohm
Two questions come up on almost every audio transformer enquiry: what the part is actually for, and why so many datasheets quote 600 ohm.
型番が決まっている場合は、サンプルまたは見積もりを依頼。
What it does
An audio transformer couples a signal magnetically between two windings. Nothing conducts across the barrier, so a ground loop between two pieces of equipment cannot push current through the signal path. That is what removes hum. The second job is impedance matching, so a source drives a load it can actually deliver power into.
Why 600 ohm keeps appearing
600 ohm is a telephone and broadcast line convention rather than a law of physics. It became the reference impedance for balanced audio lines, so parts and equipment were built around it. A 600:600 transformer is a 1:1 isolation part; a 600:150 part steps impedance down by four, which is a 2:1 turns ratio.
How to wire and verify it
Identify the primary, secondary and any centre tap from the datasheet pinout, not from the physical symmetry of the package. Keep the balanced pair symmetric on the board. Then measure insertion loss and frequency response on your own hardware, because the published curve is taken under the datasheet's stated source and load.
よくあるご質問
Audio transformer questions engineers ask
Answers cover function, the 600 ohm convention, wiring and interchange limits.
What does a 6 PIN audio transformer let me do?
Six pins can bring out both ends plus a tap on each winding, so one part serves a balanced stage on the input side and a balanced stage on the output side. It also allows winding halves to be used separately where the datasheet permits it. Read the pinout before assuming any particular arrangement.
Is a 6 PIN part always better than 5 PIN?
No, it is more flexible, which is not the same thing. More pins mean a larger footprint and a layout that is more sensitive to asymmetry between the balanced legs. If the circuit only needs one tap, a five-pin part is easier to lay out and easier to route cleanly.
How do I keep a balanced stage balanced?
Keep the two legs of each pair the same length and route them as a pair with a continuous reference plane underneath. Asymmetry between the legs converts common-mode noise into differential noise, which is exactly what the transformer was fitted to avoid. Verify on the board, not on the schematic.
Can I use only part of a winding?
Only if the datasheet says so. Using half a winding changes the effective turns ratio and the level at which the core saturates, and the impedance figure quoted for the full winding no longer applies. Where a part supports it, the datasheet states the ratio for each tap combination.
How do I request samples or a quote?
With a complete part number, send the part number, quantity, delivery region and the date you need it. If you are still selecting, send the source and load impedance, signal level, frequency range and whether both stages must be balanced, and a sales engineer will confirm candidates.
