Hi-pot class
WHTT6010 lists 4,600 VAC hi-pot, WHTT6033 3,880 VAC and WHTT6016 3,750 VAC, for products whose standard asks for a high test voltage across the barrier. WHTT6017 lists 1,500 VAC, WHTT6001 1,250 VAC and WHTT14131 1,200 VAC.

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.

Series overview
Comparing 6-pin audio transformers
A 6-pin audio transformer has six connections on one isolating part, enough for a tap on each winding, for circuits that need a reference point on both sides. It is also listed as a dual center tap transformer or dual tap audio transformer. The parts here span hi-pot ratings from 1,200 VAC to 4,600 VAC and heights from 4.4 mm to 7.5 mm, in SMD and DIP mounting. For simpler stages, compare 4-pin audio transformers or 5-pin audio transformers with a single tap.
Height and body
WHTT6010 and WHTT14131 measure 14 × 8 × 4.4 mm, the low-profile options. WHTT6016, WHTT6033 and WHTT6017 stand 7.5 mm tall, so check enclosure clearance; WHTT6016 is 13.5 × 10.0 × 7.50 mm overall.
SMD or through-hole
WHTT14131 is the through-hole (DIP) part, with a rated impedance ratio of 600:316 listed in the selector and 1,200 VAC hi-pot. The others are SMD; WHTT6001 lists the same 600:316 rating in a 13.2 × 8.2 × 5 mm body.
Winding resistance
WHTT6016 is the high-impedance part, listed with a rated impedance ratio of 10000:10000 in the selector. WHTT6016 lists 1,620 Ω of DC resistance per winding, against 30 Ω and 38 Ω for WHTT14131 and 50 Ω per winding for WHTT6017.
Applications
Applications for 6-pin audio transformers
Taps on both windings earn their place when the signal is balanced on both sides.
Balanced in, balanced out
Broadcast, studio and conferencing interfaces keep a balanced line balanced through an audio isolation transformer. WHTT6001, 1:1 at ±1% with 1,250 VAC hi-pot, suits balanced line-level paths of this kind.
Lines that leave the equipment
Where a line runs outside the product, such as telephone, intercom or public address wiring, the higher hi-pot parts add isolation margin: WHTT6010 lists 4,600 VAC and WHTT6033 3,880 VAC.
Wave-soldered and legacy boards
Boards built with through-hole parts, or older designs kept in production, can use WHTT14131 in DIP form. Its datasheet is the only published file, so plan the footprint from it.

FAQ
6-pin audio transformer FAQ
Manufacturing, turns ratios and hi-pot ratings against the 4-pin range.
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.
Is VOOHU a 6-pin audio transformer manufacturer?
Yes. VOOHU manufactures 6-pin audio transformers in its own magnetics factory in Mianyang, China. The range includes higher-isolation parts such as WHTT6010, rated 4,600 VAC hi-pot, and a through-hole option, WHTT14131, for mixed SMD and through-hole boards.
Which 6-pin parts list a 1:1 turns ratio?
WHTT6016, WHTT6001 and WHTT6033 are 1:1 audio transformers at ±1%, and WHTT6017 is 1:1 at ±2%. WHTT6010 and WHTT14131 show no ratio in the selector, so take it from their datasheets before relying on a signal level or termination.
Do 6-pin audio transformers reach higher hi-pot ratings than 4-pin parts?
In the current selector data, yes. WHTT6010, WHTT6033 and WHTT6016 list 4,600 VAC, 3,880 VAC and 3,750 VAC. 4-pin audio transformers are listed from 1,000 VAC to 1,650 VAC, so ask our FAE team if you need high isolation without taps.
