        低成本高品質的Bomar Quartz Crystal

        低成本高品質的Bomar Quartz Crystal,Bomar was founded in 1963, as a manufacturer of quartz crystals to the commercial and two-way radio industries. The nature of the business required tight tolerance and high stablility crystals over a wide frequency range, in order to meet stringent FCC specifications. The need to be produced quickly was important to our growing base of customers. Many of our customers were local, state and federal police and surveillance agencies. Bomar soon became not only the leading supplier in this market, but was consistently recognized for quality of product, quick turnaround times and unsurpassed customer service.

        In 1988 Bomar began to build an OEM customer base. Customers from the telecommunications, computer, medical, security, commercial and industrial markets began to use not only crystals, but also clock oscillators, VCXOs and TCXOs. To meet this change in product requirements we redesigned our manufacturing processses and added new manufacturing equipment to produce crystals and oscillators in smaller packages with higher frequencies, low phase noise and low jitter. With these changes and the addition of state of the art test equipment, Bomar's domestic manufacturing facility continues to provide frequency control products with the same quick turnaround, high reliability, tight tolerance and stability that it has since 1963.

        During the strong growth years in the early 90's, Bomar developed close working relationships with a few select Asian factories to manufacture products to Bomar specifications. These relationships were established only after Bomar qualified their processes and products. Today, Bomar has low cost sources for high volumes of crystals, clock oscillators, VCXOs and TCXOs continuing our 50 year commitment to providing high performance frequency control solutions that meet or exceed customer expectations in terms of price, quality and customer support.


        Bomar成立于1963年,是商業和雙向無線電行業的SMD石英晶體制造商。業務性質要求在寬頻率范圍內具有嚴格的容差和高穩定性晶體,以滿足嚴格的FCC規范??焖偕a的需求對我們不斷增長的客戶群非常重要。我們的許多客戶是當地、州和聯邦警察和監控機構。Bomar不僅很快成為該市場的領先供應商,而且在產品質量、快速周轉時間和無與倫比的客戶服務方面也獲得了一致認可。

        1988年,Bomar開始建立OEM客戶群。電信、計算機、醫療、安全、商業和工業市場的客戶不僅開始使用晶體,還開始使用時鐘振蕩器、VCXOs和TCXOs。為了滿足產品需求的這一變化,我們重新設計了制造工藝,并增加了新的制造設備,以生產更小封裝、更高頻率、低相位噪聲和低抖動的晶體和振蕩器。隨著這些變化和最先進的測試設備的加入,Bomar的國內制造工廠繼續提供頻率控制產品,具有自1963年以來相同的快速周轉、高可靠性、嚴格的公差和穩定性。低成本高品質的Bomar Quartz Crystal.

        在90年代初的強勁增長期間,博瑪與一些精選的亞洲工廠建立了密切的工作關系,生產符合博瑪規格的產品。這些關系是在Bomar對其工藝和產品進行認證后才建立的。今天,Bomar擁有大量石英晶振、時鐘振蕩器、VCXOs和TCXOs的低成本來源,繼續我們50年來的承諾,提供高性能頻率控制解決方案,在價格、質量和客戶支持方面滿足或超過客戶的期望。

        晶體(XTAL)-正確切割和安裝的石英晶體成為高質量的計時設備,通過向貼片石英晶振附近或晶體上的電極施加電壓,可以使其在電場中彎曲。這種特性被稱為壓電性。當磁場消失時,石英會產生一個電場,因為它恢復到原來的形狀,這可以產生一個電壓。石英晶體就像一個由電感、電容和電阻組成的電路,具有精確的諧振頻率。

        石英晶體可用于標準微處理器頻率或定制頻率,具有緊密的穩定性,采用金屬或陶瓷支架,并提供通孔或表面貼裝封裝。

        單片晶體濾波器采用通孔封裝,適用于各種應用。

        Bomar晶振提供幾種不同的音叉晶體,包括表面貼裝和通孔。雖然通常音叉晶體是32.768千赫,其他頻率是可用的。
