The \u003cstrong\u003e48.250 MHz Crystal Oscillator\u003c\/strong\u003e provides a highly stable clock signal tailored specifically for high-speed microcontrollers, telecom equipment, and wireless communication modules.\u003c\/p\u003e\n\n\u003cp\u003eAvailable at Tomson Electronics, this crystal is housed in the \"Big\" \u003cstrong\u003eHC-49\/U\u003c\/strong\u003e package. This traditional, taller metallic can features longer radial leads and a larger body, making it exceptionally easy to handle, plug into standard prototyping breadboards, and solder onto through-hole perfboards. Operating at 48.250 MHz, it is an essential timing component for repairing specific RF receivers or building custom high-frequency digital logic boards.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAlso searched as:\u003c\/strong\u003e 48.25mhz quartz crystal, hc-49\/u tall crystal, big crystal oscillator, rf timing component, 48.250 clock.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch5\u003eTechnical Specifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Frequency:\u003c\/strong\u003e 48.250 MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Type:\u003c\/strong\u003e HC-49\/U (Tall \/ Large profile)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Through-Hole (2-Pin Radial)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Tolerance:\u003c\/strong\u003e Typically ±20ppm to ±30ppm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Capacitance:\u003c\/strong\u003e Typically 18pF to 20pF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOscillation Mode:\u003c\/strong\u003e Often 3rd Overtone (Typical for frequencies above 30MHz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e -20°C to +70°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eCommon Applications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRF Communications:\u003c\/strong\u003e Providing precise oscillation for radio transmitters, receivers, and custom wireless transceiver modules.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Speed Microcontrollers:\u003c\/strong\u003e Acting as the external clock source for advanced processors that require a fast, stable timing signal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTelecom Equipment:\u003c\/strong\u003e Repairing or designing specific telecommunication and networking hardware that relies on the 48.250 MHz frequency band.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrototyping:\u003c\/strong\u003e Easily plugging into breadboards for testing custom high-frequency logic circuits.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eFrequently Asked Questions\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does it matter which way I plug this in?\u003c\/strong\u003e\u003cbr\u003e\nA: No. Quartz crystals are completely non-polarized components. You can insert the two pins in either direction into your circuit without causing any damage or affecting the oscillation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Do I need to use external capacitors with this?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes. In standard Pierce oscillator configurations, you will need to add two small ceramic load capacitors connected to ground—one on each pin of the crystal—to ensure the oscillator starts up reliably and maintains the correct frequency.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between this \"Big\" crystal and the \"Short\" ones?\u003c\/strong\u003e\u003cbr\u003e\nA: The difference is physical. This is the older, taller HC-49\/U package, while the \"short\" version is the low-profile HC-49\/S package. Electrically they perform the exact same function, but this taller version is generally preferred for breadboarding due to its size.\u003c\/p\u003e\n\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × 48.250 MHz Crystal Oscillator (HC-49\/U Large Package)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TOMSON ELECTRONICS","offers":[{"title":"Default Title","offer_id":49516484460782,"sku":"OSC-02010","price":9.24,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/48.250MHzBIGCRYSTAL.jpg?v=1788114869","url":"https:\/\/www.tomsonelectronics.com\/products\/48-250-mhz-crystal-oscillator-hc-49-u-large-package","provider":"Tomson Electronics ","version":"1.0","type":"link"}
