XL-302SURC 产品概述

一、产品简介

XL-302SURC 是成兴光(Xinglight)推出的一款直插式 3mm 圆头红色发光二极管(LED),俗称 F3 白发红(短脚)插件LED。该器件采用透明无色透镜和小角度发光设计,适合需要高指向性与较高亮度的指示与显示场合。结构稳定、封装成熟,便于通孔安装与自动插件生产线应用。

二、主要参数

  • 型号:XL-302SURC
  • 封装:插件,D = 3mm(圆形灯头)
  • 发光颜色:红色(白体发红)
  • 波长:615 nm ~ 620 nm(典型);峰值波长 625 nm
  • 发光角度:30°(高指向性)
  • 发光强度:1200 mcd(典型)
  • 正向电流(IF):30 mA(额定)
  • 正向压降(Vf):2.2 V(典型)
  • 功率:70 mW(上限或相关额定)
  • 工作温度范围:-25 ℃ ~ +85 ℃
  • 透镜颜色:无色透明透镜
  • 品牌:Xinglight(成兴光)

三、电气与光学特性

  • 光谱:该器件在可见红光区域发射,主观呈鲜明红色。供应商给出波长区间为 615–620 nm,峰值测量处可见 625 nm 的谱峰,表明光谱稍偏长波端但仍属红色范围。
  • 亮度与角度:1200 mcd 的发光强度配合 30° 的半角(或全角视差小),适合需要集中、远距可见的指示灯或光点显示。
  • 驱动电气特性:典型正向压降约 2.2 V,在接近额定电流工作时应考虑 Vf 的变化并配置限流措施。额定正向电流 30 mA 为器件最大连续工作电流,建议在应用中根据可靠性与亮度需求进行合理取舍。

四、封装与外形

  • 直插式 (Through-hole) 3mm 圆头设计,透明透镜利于光学一致性与视觉效果。
  • 短脚设计(F3 白发红 短脚)便于在 PCB 上低轮廓安装并减少机械应力。
  • 常见于面板指示、仪表盘与传统插件工艺产品的替换件。

五、驱动与使用建议

  • 串联限流:推荐使用串联电阻限流,计算公式 R = (Vcc − Vf) / If。为延长寿命和保证稳定性,实际工作电流通常建议在 10–20 mA 之间,尽量不要长期满额定 30 mA。
    • 例:Vcc = 5 V,若 If = 20 mA,则 R = (5 − 2.2) / 0.02 ≈ 140 Ω,阻器功率 P ≈ I^2 × R ≈ 0.056 W,选择 1/4 W 即可。
    • 例:Vcc = 3.3 V,If = 20 mA,则 R ≈ 55 Ω。
  • 脉冲驱动:若采用脉冲驱动以达到更高瞬时亮度,须严格控制占空比与峰值电流,避免超过器件极限。
  • 散热与环境:工作时注意周围环境温度上升会影响 Vf 与光输出,建议在高环境温下降低工作电流以保障长期可靠性。

六、储存、焊接与可靠性

  • 储存:建议置于干燥、避光、常温环境,避免潮湿与强紫外线直接照射,长时间存放应防止氧化与膜层损伤。
  • 焊接:遵循插件元件常规焊接工艺,避免对 LED 透镜施加机械应力。若采用波峰或手工焊接,控制加热时间与温度,避免长时间高温。
  • 可靠性:在推荐工作电流与温度范围内使用能获得稳定的光输出和长寿命;超出额定条件会加速寿命衰减或造成失效。

七、典型应用场景

  • 仪表指示灯、面板状态指示
  • 家电与消费电子指示灯
  • 工业控制面板、信号指示
  • 精密设备或仪器的指示点光源
  • 教育、示教板及装饰性照明点阵

总结:XL-302SURC 以其小巧的 3mm 圆头封装、高指向性(30°)和较高的发光强度(1200 mcd)适合各类需要集中特定指示光点的应用场景。使用时应注意限流、温度管理与合理的焊接工艺以保证长期稳定性与可靠性。若需详细的电气特性曲线、光学分布图或封装尺寸图,请提供需求以便获取完整数据手册。

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
