The oscillator coil is intended to tune from 990 to 2070 kHz using a 65pF variable capacitor for reception frequencies of 525 to 1605 kHz in transistor super-heterodyne receivers. Internal resonant capacitors are present in the IFTs. The centre pin on the IFT primaries is usually connected to +V supply, with the longer tank winding being left open circuit and the shorter winding being connected to the transistor collector. You can identify the tank and collector pins by checking the D.C. resistance readings in the sketch diagram in the pictures, where the longer tank winding has the higher resistance. As is usually the case, the pins are not on a 0.1\" pitch. The screening can tabs are 1.6mm wide. The can outer dimensions are 10 x 10 x 12.5mm. These types have some advantages in that the internal construction makes them inherently magnetically screened, and they can be adjusted without a special trimming tool.\u003c\/p\u003e\n\u003cp\u003eCare should be taken during adjustment not to wind the core in too far, as this can crash against the internal core or break the winding connections.\u003c\/p\u003e\n\u003cp\u003eYou could use these in a radio project such as that seen at the following link:\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.interestingelectronics.com\/old\/henrys_interesting_electronics\/mediumwave_radio\/mediumwave_radio.htm\" title=\"Making A DIY Superheterodyne AM Radio Like Those You Buy\"\u003eMaking A DIY Superheterodyne AM Radio Like Those You Buy\u003c\/a\u003e\u003cbr\u003e\u003cbr\u003eMore Information:\u003cbr\u003e\u003cbr\u003eCoil Type Core Colour\u003cbr\u003e\u003cbr\u003eMW OSC Red\u003cbr\u003eIFT1 Yellow\u003cbr\u003eIFT2 White\u003cbr\u003eIFT3 Green\u003c\/p\u003e","brand":"HJW Electronics","offers":[{"title":"MW OSC - Red","offer_id":58793351905664,"sku":null,"price":2.8,"currency_code":"GBP","in_stock":true},{"title":"IFT1 - Yellow","offer_id":58793351938432,"sku":null,"price":2.8,"currency_code":"GBP","in_stock":true},{"title":"IFT2 - White","offer_id":58793351971200,"sku":null,"price":2.8,"currency_code":"GBP","in_stock":true},{"title":"IFT2 - Green","offer_id":58793352003968,"sku":null,"price":2.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2136\/1280\/files\/ift_group_top_s.jpg?v=1787847726","url":"https:\/\/shop.usefulcomponents.com\/products\/465-khz-ifts-and-mw-oscillator-coil-intermediate-frequency-transformers","provider":"HJW Electronics","version":"1.0","type":"link"}
