MeLphi 8Ω: 32Ω / 32Ω: 32Ω Dedicated Audio Transformer for Headphones Mobile Phone Loudspeaker Isolation Protection Headphones (Color : Z9 32 ohm to 32ohm)

Audio TransformersThe iron core is made of Z9 material, the thickness is 0.24mm, the iron core size is EI41X33X20mm, and the high-purity oxygen-free copper enamelled copper wire. Transparent nylon frame. Transformer dimensions: 42x34x40mm. The 12 pins are soldered firmly to the circuit board. Support double panel size is 77x65mm. There are two transformers welded on the board, weighing 0.42KGThe power of the EI41X20mm core is about 5W, and the efficiency is calculated as 3W at 60%. For headphones with a power of only a few tenths of a watt, there is still a margin of 10 times.32:32 Parameters:Impedance: 32:32 (8+8:8+8), 1+1:1+1, the transformer has a center tap for the first time, it can be connected to 8:8 or 8:32, and vice versa.Primary DC resistance: approximately 34 ohmsSecondary DC resistance: about 14 ohmsPrimary inductance: about 3.1H measured at 100HZSecondary inductance: about 3.1H measured at 100HZOver signal current 60mADC withstand voltage: 500VFrequency response: 10HZ-27KHZ -1DB, 41K -2DB***************************************************** ****************************************There are also 8:32 headphone/power amplifier digital audio isolation transformers with the same specifications and sizes, and DC isolation protection headphone transformers specially produced for general power amplifier 32 headphones.Ordinary power amplifiers have a 4 ohm or 8 ohm output, the output is connected to an 8 ohm transformer, and the transformer output is connected to a 32 ohm headphone. If the AC and DC impedances of the two are the same, the transformer can obtain the best matching effect.8:32 Transformer parameters:Impedance: 8:32 (2+2:8+8), 1+1:2+2, the transformer has a center tap for the first time, it can be connected to 2:8 or 8:32, and vice versa.Primary DC resistance: approximately 4.5 ohmsSecondary DC resistance: approximately 2.1 ohmsPrimary inductance: about 3
