  • 电源纹波抑制比(PSRR): 45dB @ 120Hz
    • 在 120Hz 的频率下,电源纹波抑制比达到 45dB,这意味着该稳压器能够有效地抑制输入电源中的噪声和纹波。
  • 输出极性: 正极
    • 输出为正极,这是大多数电子系统所需的标准配置。
  • 输出电压: 8V
    • 固定输出电压为 8V,适用于需要此特定电压的应用。
  • 输出电流: 150mA
    • 最大连续输出电流为 150mA,足以满足中小型电子设备的需求。
  • 输出类型: 固定
    • 输出电压是固定的,不需要外部调整元件。
  • 输出通道数: 1
    • 该稳压器具有单个输出通道。

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.
