AR05BTCW2502 产品概述
一、概述
AR05BTCW2502 是 Viking（光颉）系列高精度薄膜贴片电阻，封装0805（约2.0 × 1.25 mm），阻值为25 kΩ，额定功率125 mW，精度达±0.1%。该器件以优良的温度稳定性和长期可靠性为特点，适用于对阻值精度与温漂有较高要求的精密电路。
二、主要规格
- 阻值：25 kΩ
- 精度：±0.1%
- 功率：125 mW（额定功率）
- 工作电压：150 V（最大）
- 温度系数（TCR）：±25 ppm/℃
- 工作温度范围：-55 ℃ ~ +155 ℃
- 封装：0805（贴片）
- 类型：薄膜电阻
三、产品特点
- 高精度：±0.1% 阻值公差，适合精密分压、参考网络及增益设定。
- 低温漂：±25 ppm/℃ 的小温度系数，保证温度变化下阻值稳定，利于测量和校准精度。
- 小型化：0805 封装在有限板上提供良好密度与可布局性，兼顾体积与性能。
- 稳定可靠：薄膜工艺带来低噪声、良好的长期稳定性及抗环境变化能力。
- 宽温工作：-55 ℃ 至 +155 ℃ 的工作温度范围，满足工业级及部分汽车电子环境需求。
- 贴片工艺兼容：适用于常规 SMT 回流焊装配工艺，便于自动化生产。
四、可靠性与注意事项
- 在实际应用中需关注功率与温升，遵循制造商的功率降额曲线以避免过热。
- 最大允许工作电压为150 V，电路设计时应确保器件两端电压不超过该值。
- 尽量避免在极端冲击或强腐蚀环境长期使用，焊接和清洗工艺应符合器件制造商推荐流程。
- 建议在电路板布局时考虑散热和过孔布局，以利于功率散发与环境温度控制。
五、典型应用与选型建议
- 精密测量仪器、数据采集与传感器接口
- 基准电路、分压器与放大器反馈网络
- 工业控制、通信设备及要求高稳定性的模拟电路
- 在选型时，若电路存在较高功率或高电压，应选择更大功率或更高电压等级的封装/型号；若对噪声或长期漂移有更严苛要求，可与厂家确认长期稳定性与批次一致性。
六、包装与订购
AR05BTCW2502 由 Viking（光颉）提供，常见为卷带（reel）包装，便于 SMT 贴装。订购时请注明阻值、精度、封装及数量，若用于关键应用，建议索取并参照最新数据手册与可靠性报告以确认工艺与环境适配。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
