XL-DA2481SRBC 产品概述

一、产品简介

XL-DA2481SRBC 是成兴光(Xinglight)推出的一款 4 位 7 段 LED 数码管,字符高度 0.28 英寸(约 7.11 mm),红光显示,采用共阴(common‑cathode)结构,封装为通孔 DIP,外形尺寸 32.2 × 10.2 mm。产品设计面向一般显示与指示类应用,兼顾可读性与可靠性,适用于仪表、计数器、时钟、家电与消费电子等场合。

二、主要参数

  • 显示位数:4 位 7 段
  • 字符尺寸:0.28 英寸(约 7.11 mm)
  • 显示类型:7 段,红色 LED
  • 极性:共阴(各位管阴极共用)
  • 发光强度:20 mcd(出厂标称)
  • 正向压降 Vf:约 2.0 V(典型)
  • 最大耗散功率 Pd:36 mW(单个发光单元)
  • 工作温度:-30 ℃ ~ +70 ℃
  • 封装:DIP,外形尺寸 32.2 × 10.2 mm(具体引脚排列请参照产品机械图)

三、电气与热特性说明

  • 单段最大耗散功率 Pd 与正向压降 Vf 联合决定了单段允许的最大直流电流。理论上 If_max ≈ Pd / Vf,按给定数值 If_max ≈ 36 mW / 2.0 V ≈ 18 mA(此为近似值,请以最终数据手册中的绝对最大额定值为准)。
  • 在高温环境下,应考虑功耗降额和亮度变化,长期工作接近上限温度时建议降低驱动电流以延长寿命并保证均匀性。
  • 共阴结构说明:所有位的阴极脚并联,便于单独对位进行位选驱动(位选脚接地以点亮相应位)。

四、驱动与应用建议

  • 串联限流电阻计算公式:R = (Vdrive − Vf) / If。示例:若 Vdrive = 5 V,目标 If = 15 mA,则 R = (5 − 2) / 0.015 ≈ 200 Ω;若 Vdrive = 3.3 V,If = 15 mA,则 R ≈ 87 Ω(可选 82 Ω 标准值)。
  • 多位扫描(动态刷新)常用于 4 位数码管,典型占空比 1/4。为保持视觉亮度,可在保证不超过器件绝对最大脉冲或热限制的前提下适度提高峰值电流,但需参考完整数据手册并留有安全裕量。
  • 推荐使用限流电阻与驱动晶体管或专用驱动芯片(带电流限制和防短路保护)以确保稳定驱动与保护元件。

五、封装、安装与可靠性建议

  • 封装为通孔 DIP,便于手工装配和波峰焊。焊接时应遵循厂方推荐的温度曲线与时间,以免损坏 LED 或造成引脚氧化。
  • 防静电、防潮存放;装配过程中避免用力挤压发光窗或直接接触发光面。
  • 若用于振动或户外环境,请在设计时考虑机械固定、胶封或遮光罩以提高耐久性与可视性。

六、典型应用场景

  • 工业与实验室仪表、数字电表、计数器、温湿度显示单元。
  • 家用电器面板、厨房秤、厨房定时器等需要四位数显示的设备。
  • 教育与开发板、原型设计中作为可视化数值显示模块。

注:本文为基于给定参数的产品概述。用于最终设计或量产前,请以成兴光正式数据手册与机械图纸为准,并在关键应用(如脉冲驱动、高温长期工作)中与厂方技术支持确认具体绝对最大额定与推荐驱动条件。

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
