  • 封装/外壳: TO-226-3,TO-92-3(TO-226AA)(成形引线)
  • 供应商器件封装: TO-92-3

电气性能

KSC1845FTA 的电流增益 (hFE) 最小值为 300,这使得它在低电流(如1mA)情况下仍能保持良好的放大能力。这一特性非常适合用于信号处理电路,能够有效提升微弱信号的强度。此外,该晶体管具有 50mA 的集电极电流限制,使其在设计时具备一定的灵活性。

频率响应

该器件的跃迁频率高达 110MHz,能够支持高频信号的放大和开关应用。这对于需要高频率响应的 RF 设计和其他高速电路来说,KSC1845FTA 是一个理想的选择。

耐压能力

KSC1845FTA 的集射极击穿电压最大可达 120V,这意味着它在高压应用中具有相对较高的稳定性。此外,其集电极截止电流(ICBO)高达 50nA,表明该器件在关闭状态下漏电流极小,适合用于低功耗设计。

功率与散热

另一个值得关注的特点是其最大功率阈值为 500mW,允许器件在一定功率水平下正常工作。这对于电源管理和功率放大应用也是一个重要的考虑因素。由于该器件的工作温度上限为 150°C,设计者在设计散热方案时需考虑到这一点,以确保晶体管在高温条件下的可靠运行。

应用领域

KSC1845FTA 可广泛应用于多种电子产品中,例如:

  • 音频放大器: 在音频信号处理中,KSC1845FTA 可以用作前置放大器,提高信号的可识别性。
  • 开关电路: 由于其较低的 Vce 饱和压降,该器件适合用于开关电路,可以有效地控制电流和电压。
  • 射频应用: 其高跃迁频率使其在 RF 射频领域也具有一定的应用,如无线通信设备中的信号调制与放大。

封装与安装

KSC1845FTA 采用 TO-92-3 封装形式,适合多种 PCB 设计,具有成形引线,便于通孔安装。该封装小巧且结构简单,方便在高密度电路板上使用,提高了整体设计的灵活性。

结论

综上所述,KSC1845FTA NPN 三极管凭借其高增益、高频率和适中的功率处理能力,成为了众多电子设计中的优先选项,无论是消费者产品还是工业应用,均能满足广泛的电气性能需求。对于追求高效、稳定和优良信号处理的电路设计者而言,KSC1845FTA 无疑是一个值得推荐的电子元件。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
