XL-DB5261SRBC 产品概述

一、产品简介

XL-DB5261SRBC 是成兴光(Xinglight)出品的 0.56 英寸双位 7 段 LED 数码管,红色发光、共阳极封装(DIP)。字符高度为 0.56"(约 14.2mm),单颗发光强度典型值 20 mcd,适用于仪表、家电面板、计数器、显示模块及各种状态指示场合。器件结构紧凑(外形尺寸约 25 × 19 mm),便于通用 PCB 插装与批量生产装配。

二、主要技术参数

  • 显示位数:2 位(双位 7 段)
  • 字符尺寸:0.56"(约 14.2 mm)
  • 显示类型:7 段(含小数点)
  • LED 极性:共阳(Common Anode)
  • 发光颜色:红色
  • 发光强度:20 mcd(典型)
  • 正向压降(Vf):约 2.0 V(红色 LED)
  • 最大耗散功率(Pd):36 mW(单段)
  • 工作温度范围:-30 ℃ 至 +70 ℃
  • 封装形式:DIP,外形约 25 × 19 mm
  • 品牌:Xinglight(成兴光),型号:XL-DB5261SRBC

三、功能特点与优势

  • 共阳设计,便于采用低端驱动(下侧开关)或 MCU/驱动芯片进行段选控制。
  • 0.56" 字号在可读性与板面占用间取得平衡,适合中小型面板显示。
  • 红色发光对比度高,夜间和弱光环境下辨识度好。
  • DIP 插装工艺兼容常见手工焊接和波峰/回流插装设备,可靠性高。

四、驱动与应用建议

  • 推荐工作电流(每段):5–15 mA;因最大耗散功率约 36 mW,按 Vf=2.0 V 计算,单段连续最大电流约 18 mA,应避免长期超过此值以延长寿命。
  • 限流电阻计算:R = (VCC − Vf) / I
    • 例如 VCC=5V,I=10mA:R ≈ 300 Ω
    • VCC=5V,I=18mA(近最大):R ≈ 167 Ω(可取 180 Ω)
  • 共阳极驱动要点:共阳脚连接至正电源,段选由下端(低电平)或下侧开关器件(NPN 或 N-MOSFET)完成。进行多位扫描(静态或动态)时,注意占空比对单段平均电流的影响,动态驱动时需适当提高峰值电流但不得超过器件限值。
  • 若采用多位多路复用,建议在驱动器端加入短路保护及限流电阻,防止瞬态过流。

五、安装、可靠性与注意事项

  • 焊接:推荐遵循常规 DIP 元件焊接工艺,避免在高温下持续加热,手工焊接应尽量缩短加热时间。
  • 储存:避免潮湿、高温及强光直射,长期储存建议防潮包装。
  • 使用环境:适用于室温及工业级常见温度范围(-30 ℃ 至 +70 ℃),不建议在极端环境(高温高湿或强腐蚀气氛)长期使用。
  • ESD 保护:LED 芯片对静电敏感,使用过程中注意静电防护。

六、典型应用场景

  • 仪表仪器、计数器、数字钟表、家用电器面板、工控设备状态显示、教育与开发板演示等需要可视化数字显示的场合。

XL-DB5261SRBC 以其通用的 0.56" 字号、易于驱动的共阳结构和可靠的 DIP 封装,适合作为多数点阵/段式数字显示方案中的标准元件。选型时请依据系统电源、电流预算及散热条件合理配置限流与驱动电路,确保长期稳定运行。若需完整引脚图与详细电气特性曲线,请联系供应商获取完整数据手册。

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
