XL-DA3161SRBC 产品概述

一、产品简介

XL-DA3161SRBC 是成兴光(Xinglight)推出的一款单位数红色 7 段 LED 数码管,字符高度 0.36 英寸(约 9.1 mm),采用共阴(共阴极)构型,适合面板指示、仪表读数和各类嵌入式显示场合。封装为 DIP,外形尺寸约 14 × 7.5 mm,结构紧凑、视角和亮度适中,便于通用电路板安装与批量生产。

二、主要参数

  • 显示类型:7 段单位数(1 位)
  • 字符尺寸:0.36 英寸(约 9.1 mm)
  • 发光颜色:红色
  • LED 极性:共阴(共阴极)
  • 发光强度:20 mcd(典型)
  • 正向压降(Vf):约 2.0 V(典型)
  • 最大耗散功率(Pd):36 mW(单段)
  • 工作温度:-30 ℃ ~ +70 ℃
  • 封装:DIP,外形约 14 × 7.5 mm,14 引脚设计(常见 2.54 mm 间距兼容 PCB 插针安装)

三、典型电气特性与驱动建议

  • 建议驱动电流:一般以 10–20 mA 为常规范围;根据 Pd = Vf × If,可从 Pd=36 mW 与 Vf≈2.0 V 推算出 If_max ≈ 18 mA,因此建议常用电流不超过 18 mA,以保证可靠性与寿命。
  • 限流电阻计算示例(以单段直流点亮为例):
    • 5.0 V 电源、目标 If = 15 mA:R = (5.0 − 2.0) / 0.015 ≈ 200 Ω(取 200 Ω)
    • 3.3 V 电源、目标 If = 12 mA:R = (3.3 − 2.0) / 0.012 ≈ 108 Ω(取 110 Ω 或 100 Ω)
  • 多路扫显(共阴结构适合阵列多路扫描):在多位动态驱动时可适当提高峰值驱动电流,但需注意平均功耗与 Pd 限制,避免单段过热。建议在数据手册允许范围内并考虑占空比调整。

四、机械与封装说明

  • 封装形式为 DIP,便于直插焊接或插座安装。外型尺寸 14 × 7.5 mm,14 引脚布局适配常见 PCB 针脚间距(通常为 2.54 mm),具体引脚配置与孔位建议参照厂方详细机械图纸以保证正确安装与锡焊工艺。

五、应用场景与选型建议

  • 典型应用:小型仪表、便携式检测设备、时钟计时器、家用电器指示、教育与 DIY 项目等。
  • 选型要点:若空间受限且需单字符显示,XL-DA3161SRBC 提供稳定的红色指示;若系统驱动为 3.3 V,请确认限流与亮度需求并选择合适电阻;若进行多位扫描驱动,需设计好驱动时序与最大峰值电流保护。

六、使用注意事项

  • 遵循最大耗散功率与最大正向电流限制,避免长时间超规格驱动以延长寿命。
  • 高环境温度下亮度会有所下降,且器件热量需通过 PCB 散热设计合理释放。
  • 安装时避免机械应力作用于引脚与封装,焊接温度与时长应符合通用 LED 焊接工艺以防内部损伤。
  • 具体引脚功能与更多详细参数建议参照成兴光官方完整数据手册或向供应商索取样品及验证资料。

如需我为您提供限流电阻精确选型、驱动电路参考或 PCB 封装建议图,可告知系统供电电压及驱动方式(静态点亮或多位扫描),我将按具体工况给出更详尽建议。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
