Digi key transformer11/12/2023 Check stock and pricing, view product specifications, and order online. If you want to match a Hi-Z 50k ohm audio circuit to a Low-Z 600 ohm audio circuit you better buy a transformer that specifies 50k and 600 for the impedances.ĪFAIK, percent impedance is a specification that is typically only used for large power distribution transformers. Order Signal Transformer 10-100 (10-100-ND) at DigiKey. ![]() Pricing and Availability on millions of electronic components from Digi-Key Electronics. Usually that is all you need to successfully design it into a circuit.įor impedance matching transformers the impedance specs for the primary and secondary windings are essential. Order Signal Transformer DU-1 (595-1920-ND) at DigiKey. NA0069R LF 350µH LAN 1000 Base-T Pulse Transformer 1:1CT Transmitter, 1:1CT Receiver Surface Mount from Pulse Electronics. Often with power transformers impedances are not specified at all, only the voltage/current ratings of the primary and secondary windings and operating frequency range are given. Also, below is a snip of the dimensions from Signal Transformer’s datasheet ds-st-241-series.pdf () for reference. Scroll down the page to see the substitute options. We do have possible substitutes through Signal Transformer that have similar dimensions and specs with the same mounting hole spacing. ![]() Discontinued at Digi-Key: Autotransformer (Non-Isolated) 347V, 480V: 277V. Design Tools and Resources kits Nathan2268 July 20, 2023, 7:32pm 1 This Product Selection Guide contains information to help select products in the Transformer Kits category on Transformer Kits are groupings of transformers of different values and quantities. We currently do not carry MCI Transformer. As far as I understand transformers have no impedanceĪll types of electronic components have an impedance, often the AC and DC impedances are different, they can be difficult to measure/calculate, and/or they are not needed for using the component in an ordinary design. Isolation Transformers and Autotransformers, Step Up, Step Down are in stock at DigiKey.
